Data cable is structured cable. It does matter how you position the cables. The blue and green pairs are wound tighter than the brown and orange. This is critical in longer runs. Data reflection in the cable is important. Also you can't just stick 90° bends, they have to be sweeping bends etc. Over simplifying greatly here. But its not T&E!
as Tom said, it may not be standard but if you 568A on both ends but put the terminator on upside on both ends too, the net result is exactly the same from a functionality. the blue/white and green white pairs will still be pins 4/5 and 3/6 respectively - it's just to colour codes will be reversed.
It depends. I understood what he was saying was that the order was the complete opposite, ie Bn where WhGn should be. This means that when you plug a patch cord in you will have impedance mismatch at the sockets due to the change in twist rates. If you test this for certification you might find it fails for return loss (have personally seen this occur). For gigabit ethernet it probably won't care, but if you are running something fancy that pushes the MHz to the limit of the class it might have problems. At the end of the day if the customer is asking for certification and you can't provide it, well, the apprentice will be busy re-terminating. Technically if you run T568A in the walls your patch cords (at least during the test) should match, vis-a-vis for B.
I was coming here to make somewhat the comment. As long as you get the right wires in the right spot they work is it to the standard no. Unless the pars are split ( combining a wire from from 2 colors) you shouldn't have issues but if they put it in backwards spliting the pairs there's no guarantee something else is it messed up. To some extent flipping the two wires of the same color shouldn't matter but then you're more likely to get flipped polarities. Thankfully a lot of the equipment these days is able to adjust to most situate most of the time except for that one time you need it to work.

Those batteries are wet cell lead acid and vent a lot of acid vapor to the atmosphere while charging especially when there flat, the lid up while charging is for ventilation and heat dissipation
Lead acid cells do require ventilation. But should not produce any significant gassing until they approach being fully charged. And unless damaged, they should not normally vent acid. As they get close to being fully charged, they will start gassing, and release hydrogen gas.
Use a 3 gang plate and get a non dimming module push on/off. As for under cupboard just use a kinetic module and put the receiver/relay under the cupboard. No need for any new cabling to switch then. Kinetic now make modules to go into grids as well.
It is good to help people and give them opportunities and they are more likely to stay. But that will only work for so long. You need to think of how that person can progress in your business and different ways they can add value and profit to your business.

This can be done in a number of ways but only you can choose the most appropriate for your business.
Burgess Ceilings are used in almost every supermarket in the UK. Had many near misses over the years with them. Normally damaged by removing them with screwdrivers rather than the correct tool (looks like a bottle opener)
I'd pop back to Selco, tell her you have a position open and pass your number on. If she takes the initiative to call and find out more you know she's keen.
A big reason for the batteries is that, especially in large warehouses, you have charging rooms where you swap the batteries. I'll try and snap some pictures of the room at work next time I get the chance. Also, it's not open to touch unless somethings broken. That's why there's plastic caps on all the terminals. I'm curious about the voltage on that truck battery. The little grey square on the connector is a key and should have the voltage listed on it.
I have old Rocla forklift, it has 24v battery. I charge it with 24v "smart charger", instead of original powerhog, what generates heat more than charge.
Charging with the lid/seat open is a necessity as gas could accumulate when charging, so it's to went it out, at least for older Lead-Acid batteries, the same goes for electric work platforms, you should always be careful around those when they have been charged. Li-Ion doesnt have that issue and AGM as well I think.
34:59 Tom, write into their contract that if they do bugger off they must pay all the costs you've paid out on them within a set period of time. The set period of time usually being how long it takes them to work the cost back if that makes sense.
For example trainee bus driver, get all your training, theory and practical tests BUT if you leave within 2 years your liable for all the costs of the training.
Make sure you tell your insurance company that you have changed the wheels, if not, then they can legally void your cover. You have to tell them the slightest change from standard now.
I can actually picture them doing that. Write off your van and they're like "you didn't tell us you put fluffy dice on the windscreen this is a completely different vehicle" 😅
If you just put in the colors of a CAT6 randomly (but the same on both ends) the cheap tester will show a correct cable but it will not work with more than 10 Mbit. For full speed the twisted pairs need to be in the correct place.
@@kmcat The insulation colours on the wires don’t matter, but being paired up correctly does, especially as cable length and speed increase. I’m sure for a single short cable it’s not that important, but equally a reliable working Gigabit Ethernet connection at 80m+ running in a bundle from a cabinet to an office is going to need the right grade of cable with the correct termination to work reliably. Doubly so at 10G.
Here are the results. Tested in a live datacentre environment next to other data cables. CAT6 over 40m in T568B tested out at just under 9Gb/s, the same speed was achieved with colours randomly placed - there was a slight increase in late collisions nothing major for 10Gb CAT6 over that distance. CAT6 over 90M in T568B 1Gb/s, with colours randomly placed no to little difference CAT6a over 40m was very much the same as above, using the T568B layout but now was able to achieve around 10Gb/s upto 90m. With colours randomly placed I noticed that 10Gb/s could be achieve but our SFP+ transceiver module did bug out a little.
@@kmcat There are hundreds of different combinations you could end up with, some works and others do not. For a correct cable the following numbers must be from the same colour pair: 1&2, 3&6, 4&5, 7&8. If you want to try a really slow cable do this: 1 white/orange 2 white/green 3 orange 4 green 5 white/blue 6 white/brown 7 blue 8 brown
We have modular switches here in australia where you can pop out individual switches and swap in dimmer modules wherever and however many you need. Schneider make them so you should be able to order them in
Having more APs with smaller coverage areas will have less congestion and therefor higher bandwidth as long as they are operating on different channels, if they are using a proper WiFi mesh controller Unifi/Meraki etc then these will handle handoff, auth etc etc.
I was about to comment on that aspect. Comms, like power, may be superficially simple but there's often considerations beyond what may be "common knowledge". We've had to upgrade networking (wired and WiFi) that was specced by the installing sparky.
That radiator is straight out of the Olympic Village in Sochi 😂 also Marbo were made by a company called Marbourn, the factory was about 5 minutes from my house. They shut down about 20 years ago.
Good for you, man. It's clear you're a genuine good guy with that story about maybe hiring someone to give them a boost. I wish more people, especially electrical business owners LOL, were that way...
I wouldn't say nest vs ring is personal preference as they function different. The Nest can do 24x7 recording so it doubles up as a full on CCTV device. The Ring only records when it detects motion and both can be a little hit or miss when they detect motion enough to record even when adjusting their sensitivity. The obvious advantage being the Nest will capture anything happening regardless if motion was detected or not. Multiple times with Ring i'd have it start recording 5-10s after detecting someone on the drive making it useless. I also found the video quality superior on the Nest but this might of changed in the last couple of years with both brands having product refreshes.
@@thomasnagy it's been a long time since I last drove one and I think they are mainly lead acid batteries so when they charge they can create hydrogen.

Be careful rolling CAT6. The pairs are different twist sizes and therefore each pair is a different length. This means you need to wire CAT6 correctly.
25:25 The forklift we use (Hyster) has the battery connections covered with an isolating material. You have to open the lid to prevent buildup of hydrogen gas while charging. I guess the reason why forklift batteries are charged that way is because in intensive use scenarios (distriubution centres) often the whole battery pack is changed for a charged one to keep the forklift or reach truck running. Downtime must be kept to a minimum.
Also Tom, just incase you weren’t aware (which I’m sure you are) it does matter how cat6 is terminated. Each pair is twisted at a different rate which enables no distortion between the pairs. for the most part it should be fine but I have been told that equipment such as cctv cameras might not work and will need to be terminated correctly. I’m sure you knew all this but just for anyone else out there!
Although you will get a link up so long as you match both ends over Catx, if the colour pairs weren't correctly matched they will likely experience problems at 1000BASE-TX from alien cross-talk and environmental EMI. The point of twisted pair is to provide some cancellation of signal noise on +ve and -ve signal pairs. This would be compounded by other demands, like POE or 802.3bz-2016 data rates like 2.5GBASE-T and 5GBASE-T which are supported at reasonable distances on correctly terminated Cat5e and are becoming attractive for existing commercial installations that need higher data rates.
I'm pretty sure the order of the wires in Ethernet cables does matter. Sure, it works as long as you replicate the order on either side but twisted pair is twisted into unique pairs for a reason, it is an interference mitigation technique. If you order the pairs wrong, you have the potential for unintended/unaccounted-for crosstalk. It works but it may not certify at super high data speeds.
Forklift question. While it is dangerous, these are often managed by professionals. There is value in seeing the battery and having access to water ports. Some batteries have plastic guards to protect contacts. Being fully visible allows for easy inspection. If it was fully enclosed, catching an issue would require removal of guards and would often be overlooked as forklifts are often production sensitive. I could go deep in this but suffice it to say, Things can be dangerous. Safety third.
A “Chint” board is the last board in the wholesalers and you need one right now! I fitted one just to try one. I liked the solid neutral cables as well that’s why decided to try one. Don’t think I’ll ever fit another!
Loved the chair at the end. I have a hammock in my van when I'm on nights and not on a call out. I know that sounds bad sleeping in work but it's a job that is unpredictable for emergency calls.
Hi To - I would like to offer a suggestion to your mention that any combination of wire colors can be used as long as it is consistent at the other end. That might have easily been true with CAT-3, though with the higher speeds it is quite important that the -A or -B wiring standard is followed. The impedance, frequency response, etc. of the cable and connection relay on which wire/pair in the four pairs carry the signal.
The earth wire being longer is what I got taught in electrical school in Finland. Applies to all plugs. Three phase is the normal in homes here, but my main fuses are only 20A*3. 25A and 32A is quite common also. And the batterypack is lead-acid, so you get explosive gasses while charging, the new with lithium have a "external" socket. At least the Toyota forklifts at my work have it this way.
I know Varilight do dummy dimmer modules which act like push on/off switches. Most dimmer modules fit a standard hole, so probably would work on a Schneider plate. Alternatively you can get dual dry line boxes to mount two single gang accessories side by side (subject to plate size - doesn’t work with some decorative accessories). Failing that, you can join two single dry-lining boxes together with a small wooden spacer so that the accessories butt up together neatly; slightly faffy, but have done it myself a few times.
Also if you hire very experienced people it's likely that all you will ever hear is "oh, at my old place we didn't do it like that, we did it like this" and finding that they're basically completely disregarding everything you say and doing things however they like... think of a 25 year old chef trying to tell 65 year old nana how to cook roast potatoes...

Forklift batteries are designed to be changed. Some places run forklifts 24/7 so when the battery is flat, you switch it for another battery. This is why they are unpluggable. Some forklift batteries can be plugged into the charger without opening up the battery cover. Still is one manufacturer that comes to mind. Also, you are supposed to top up the water in the batteries daily as well. You need access to the cells to do this, although some manufacturers have a quick release fitting on the charging lead so the water is topped up when you plug it into the charger.
Hi forklift battery's a 72V 480ah someone forgot to lift the seat cover up for the gases to escape. next morning seat was by the side of truck, gas had exploded sent the steal battery cover with the seat attached 8M up smashed a hole in the roof. Just glad no one was sat on it.
I love stuff like that radiator , when the game is trying to work out exactly what was going through the head of the person who would do something like that. Dont label up cable like that , just patch them all in to the panel and re label after , saves loads of time. Room that size , 4 APs One in each corner. But please dont do direct runs like that , put a socket in the celling and put a patch cable. You are not supposed to put sloid cable into glass ends like that. Its also better for servicing when its time to upgrade the AP.
When i worked for a council doing cctv, fire alarms, emergency lighting etc when working in the civic centre, the ceiling was very similar, it had a little lip on each panel that would slide into, no lock, it meant get it wrong and it would fall, taking all other ceiling panels with it. This was so bad that you could only work on the ceilings when there was nobody in at the weekends
I have seen it before with the half radiator but usually its landlords halving all the rooms to get as many tenants in as possible regardless of rads windows etc. Same with a wall splitting a large window and its clearly one large room split into two.
Regarding the forklift. That battery setup looks exactly the same as the 2 in my workshop. They are not maintenance free batteries and have to be checked/topped up after every charge. I believe they are also a lead acid battery which shouldnt be charged in enclosed spaces (?). I'm sure it comes down to cost, and when these were first installed Lithium batteries cost an arm and a leg? It might also be max current draw and Lithium can't deliver. Someone more or less qualified then me knows more I'm sure. Just my 2 cents from the Land Down Under.
Definitely agree with your idea of taking someone on and helping them. I think they would more than likely stay with the business also because of your kind attitude. Do it nagy
In australia we have plates for swithces, dimmers etc that range from 1 gange to 6 gangall in an approx 125x85mm. YOu can also get blanks to cover up any extra holes and you can pull switch mechs out and put them straigh into a new plate making it nice and easy to add and extra switch (assuming there is space behind it)
Another great video I've been watching you for a long time and lately I've been thinking about starting my own company the company I work for does not looks so secure as used to in the past. Your inspiration to electricians and I quite enjoy watching your videos be safe and have a great day
I think, that they do the forklift charging designs because there can be gasses etc coming from the batteries when charging, and this forces you to have it open, not 100% sure tho
Lead acid batteries need ventilation when charging and are a pain to charge take a full day to charge, places like screw fix have a battery room loads of ventilation and shelves for charging batteries to sit on, you swap your battery and off you go.
Server rooms are usually restricted because of sensitive info on the servers, and the importance of keeping servers online. They could let you in escorted, but that's a huge waste of the escorts time. Cable order is important for equipment interoperability. The Type B wiring standard is the most common, you might find Type A in US government installs. Good call on the service loops! Second access point for redundancy!
wait... ferrules and cutting the PE longer is an option? here in germany its mandatory. But therefore we don´t have to fit a 30mA RCD above 32A as its either industrial equipment or will likely be sub-distributed. btw, you can´t just change the pinout of an RJ45. It´s a twisted pair wire for capacitance reasons, so splitting a "signal"pair across "wire"pairs impacts performance. It won´t affect you if you are only pushing 100mbits, but 10gbits on a CAt.7 will have problems.
You have seen the light…… it is at the top of pole next to a road I would have thought being in a bucket while it is pissing down in February around 4pm when the day seems to go on forever a house rewire with many pubes may be seem bliss? 😉
They make push button switches that look like dimmers. You unscrew the dimmer from the face plate and replace with the push button. Had exactly this in my old house. It wastes a dimmer module but probably cheaper than grid.

As for under cupboard just use a kinetic module and put the receiver/relay under the cupboard.
No need for any new cabling to switch then.
Kinetic now make modules to go into grids as well.
15:20 - If you prefer bars move to the U.S. We've got bars for ground, bars for neutral, and up to 3 of them for the different phase lines. :)
It is good to help people and give them opportunities and they are more likely to stay. But that will only work for so long. You need to think of how that person can progress in your business and different ways they can add value and profit to your business. The only way to retain employees who work with passion and motivation is through making them invested in your business. This can be done in a number of ways but only you can choose the most appropriate for your business.
Burgess Ceilings are used in almost every supermarket in the UK. Had many near misses over the years with them. Normally damaged by removing them with screwdrivers rather than the correct tool (looks like a bottle opener)
I'd pop back to Selco, tell her you have a position open and pass your number on. If she takes the initiative to call and find out more you know she's keen.
A big reason for the batteries is that, especially in large warehouses, you have charging rooms where you swap the batteries. I'll try and snap some pictures of the room at work next time I get the chance.
Also, it's not open to touch unless somethings broken. That's why there's plastic caps on all the terminals.
I'm curious about the voltage on that truck battery. The little grey square on the connector is a key and should have the voltage listed on it.
Forklift batteries are typically 48V, some more recent lithium ones 90V
I have old Rocla forklift, it has 24v battery. I charge it with 24v "smart charger", instead of original powerhog, what generates heat more than charge.
Charging with the lid/seat open is a necessity as gas could accumulate when charging, so it's to went it out, at least for older Lead-Acid batteries, the same goes for electric work platforms, you should always be careful around those when they have been charged.
Li-Ion doesnt have that issue and AGM as well I think.
34:59 Tom, write into their contract that if they do bugger off they must pay all the costs you've paid out on them within a set period of time. The set period of time usually being how long it takes them to work the cost back if that makes sense.
For example trainee bus driver, get all your training, theory and practical tests BUT if you leave within 2 years your liable for all the costs of the training.
Make sure you tell your insurance company that you have changed the wheels, if not, then they can legally void your cover. You have to tell them the slightest change from standard now.
I can actually picture them doing that. Write off your van and they're like "you didn't tell us you put fluffy dice on the windscreen this is a completely different vehicle" 😅
If you just put in the colors of a CAT6 randomly (but the same on both ends) the cheap tester will show a correct cable but it will not work with more than 10 Mbit. For full speed the twisted pairs need to be in the correct place.
I'm sure that's not correct, but I will try it on a 10Gbit run tomorrow at work
@@kmcat The insulation colours on the wires don’t matter, but being paired up correctly does, especially as cable length and speed increase. I’m sure for a single short cable it’s not that important, but equally a reliable working Gigabit Ethernet connection at 80m+ running in a bundle from a cabinet to an office is going to need the right grade of cable with the correct termination to work reliably. Doubly so at 10G.
Here are the results.
Tested in a live datacentre environment next to other data cables.
CAT6 over 40m in T568B tested out at just under 9Gb/s, the same speed was achieved with colours randomly placed - there was a slight increase in late collisions nothing major for 10Gb CAT6 over that distance.
CAT6 over 90M in T568B 1Gb/s, with colours randomly placed no to little difference
CAT6a over 40m was very much the same as above, using the T568B layout but now was able to achieve around 10Gb/s upto 90m. With colours randomly placed I noticed that 10Gb/s could be achieve but our SFP+ transceiver module did bug out a little.
@@kmcat There are hundreds of different combinations you could end up with, some works and others do not. For a correct cable the following numbers must be from the same colour pair: 1&2, 3&6, 4&5, 7&8.
If you want to try a really slow cable do this:
1 white/orange
2 white/green
3 orange
4 green
5 white/blue
6 white/brown
7 blue
8 brown
We have modular switches here in australia where you can pop out individual switches and swap in dimmer modules wherever and however many you need. Schneider make them so you should be able to order them in
Having more APs with smaller coverage areas will have less congestion and therefor higher bandwidth as long as they are operating on different channels, if they are using a proper WiFi mesh controller Unifi/Meraki etc then these will handle handoff, auth etc etc.
I was about to comment on that aspect. Comms, like power, may be superficially simple but there's often considerations beyond what may be "common knowledge". We've had to upgrade networking (wired and WiFi) that was specced by the installing sparky.
That radiator is straight out of the Olympic Village in Sochi 😂 also Marbo were made by a company called Marbourn, the factory was about 5 minutes from my house. They shut down about 20 years ago.
Absolutely crying at the ceiling tile rant, well done
32:17 If you short the ends, the tone will go completely silent and you know you got the right cable👍
I always fit Click Mode dimmer and switch on the same plate, doesn't look like your typical MK grid.
Good for you, man. It's clear you're a genuine good guy with that story about maybe hiring someone to give them a boost. I wish more people, especially electrical business owners LOL, were that way...
At 23 minutes "Long Earth" Yes, good idea. In my private stuff at home, I have been following that ethic for years.
Data cable connection to 568-A or 568-B. 568-B commonly used in UK.
@thomas nagy i believe the idea behind opening the seat cover is because when charging the battery`s they create a gas that can be explosive/flammable
Fitted a chint board once, had to get a pry bar to straighten the lid out! 😬
Have a look at Clipsal C2000 in Australia for the switches. you buy a plate and inserts of what ever you want
I wouldn't say nest vs ring is personal preference as they function different. The Nest can do 24x7 recording so it doubles up as a full on CCTV device. The Ring only records when it detects motion and both can be a little hit or miss when they detect motion enough to record even when adjusting their sensitivity. The obvious advantage being the Nest will capture anything happening regardless if motion was detected or not. Multiple times with Ring i'd have it start recording 5-10s after detecting someone on the drive making it useless. I also found the video quality superior on the Nest but this might of changed in the last couple of years with both brands having product refreshes.
27:36 probably it's a different business above the charity. Which has been security tested (Penetration test).
Forklift charging is to vent any hydrogen gas that might come out while it's charging.
I had no idea !
@@thomasnagy it's been a long time since I last drove one and I think they are mainly lead acid batteries so when they charge they can create hydrogen.
@@jerryuk93 like I said it's been a while since I last drove one and even long since I last did the training course. :)
I've seen the radiator through a wall in a commercial premises as well!
8ft fluorescent (on jack chains) through a partition in a place I did some work in.
That was fun changing the tube!
Dampåa ceeling, developed originaly for shipping industry...
There is a smalle metal clip for taking them down... Doesnt make the clicking system as lose as using loads of different handtools...
Volex are owned by Siemens group, but are very much still in operation.

Damn you know Thomas is back and as his grown business wise so has his content laavvvv it keep on bringing them 🌡️
One of the best videos you have done methinks. Long and varied. Thanks for taking the time to share, appreciate it ;-)
Thanks you, really appreciate it :)
Be careful rolling CAT6. The pairs are different twist sizes and therefore each pair is a different length. This means you need to wire CAT6 correctly.
25:25 The forklift we use (Hyster) has the battery connections covered with an isolating material. You have to open the lid to prevent buildup of hydrogen gas while charging. I guess the reason why forklift batteries are charged that way is because in intensive use scenarios (distriubution centres) often the whole battery pack is changed for a charged one to keep the forklift or reach truck running. Downtime must be kept to a minimum.
Seriously impressed with a 41 minute video. Have you ever been approached by a TV production company?
Also Tom, just incase you weren’t aware (which I’m sure you are) it does matter how cat6 is terminated. Each pair is twisted at a different rate which enables no distortion between the pairs. for the most part it should be fine but I have been told that equipment such as cctv cameras might not work and will need to be terminated correctly.
I’m sure you knew all this but just for anyone else out there!
Why not use those batteryless wireless switches instead of running a cable (Quinetic I think)
If you're a landlord, you do your best to avoid tech like that. (edit) Haha then he goes fit's a Ring doorbell!
a lot of people prefer hard wired stuff to all the smart technologies coming out
He'd struggle with putting the switch in with the lath and plaster. It'd also not match the rest of the property which would be an issue in this case.
Schinder Lisse do grid switch which can install 2x dimmer snd 1x standard switch I’ve done it
Although you will get a link up so long as you match both ends over Catx, if the colour pairs weren't correctly matched they will likely experience problems at 1000BASE-TX from alien cross-talk and environmental EMI. The point of twisted pair is to provide some cancellation of signal noise on +ve and -ve signal pairs. This would be compounded by other demands, like POE or 802.3bz-2016 data rates like 2.5GBASE-T and 5GBASE-T which are supported at reasonable distances on correctly terminated Cat5e and are becoming attractive for existing commercial installations that need higher data rates.
I'm pretty sure the order of the wires in Ethernet cables does matter. Sure, it works as long as you replicate the order on either side but twisted pair is twisted into unique pairs for a reason, it is an interference mitigation technique. If you order the pairs wrong, you have the potential for unintended/unaccounted-for crosstalk. It works but it may not certify at super high data speeds.
Great video as always 👍 That radiator was absolutely ridiculous - but very funny 😁😁😁😁
Glad you enjoyed it
To change the pendant in the stairwell, knock a hole in the wall and stick your bucket truck in.
The plasterer can skim it when you're done 😆
Forklift question. While it is dangerous, these are often managed by professionals. There is value in seeing the battery and having access to water ports. Some batteries have plastic guards to protect contacts. Being fully visible allows for easy inspection. If it was fully enclosed, catching an issue would require removal of guards and would often be overlooked as forklifts are often production sensitive. I could go deep in this but suffice it to say, Things can be dangerous. Safety third.
A “Chint” board is the last board in the wholesalers and you need one right now! I fitted one just to try one. I liked the solid neutral cables as well that’s why decided to try one. Don’t think I’ll ever fit another!

Mr Nagy, you get a 3gang dimmer switch on a 2gang plate and use a dummy dimmer for lights that can’t be dimmed
Loving all the content
Worked in a lathe and plaster house with 3m ceilings, and no consistency with dwang heights.
You can get dummy dimmers that look just like a dimmer but are push switches
Loved the chair at the end. I have a hammock in my van when I'm on nights and not on a call out. I know that sounds bad sleeping in work but it's a job that is unpredictable for emergency calls.
I do love that chair. I have another one set up in the office, you'll see in next weeks video ;)
They do dummy dimmer modules that are switches, gets around the non dimmable lighting on a shared plate
Exactly what I was going to say.
I would have put the WiFi above the false ceiling but good job. Its good to see your regular vids now.
Hi To - I would like to offer a suggestion to your mention that any combination of wire colors can be used as long as it is consistent at the other end. That might have easily been true with CAT-3, though with the higher speeds it is quite important that the -A or -B wiring standard is followed. The impedance, frequency response, etc. of the cable and connection relay on which wire/pair in the four pairs carry the signal.
The earth wire being longer is what I got taught in electrical school in Finland. Applies to all plugs. Three phase is the normal in homes here, but my main fuses are only 20A*3. 25A and 32A is quite common also. And the batterypack is lead-acid, so you get explosive gasses while charging, the new with lithium have a "external" socket. At least the Toyota forklifts at my work have it this way.
I know Varilight do dummy dimmer modules which act like push on/off switches. Most dimmer modules fit a standard hole, so probably would work on a Schneider plate. Alternatively you can get dual dry line boxes to mount two single gang accessories side by side (subject to plate size - doesn’t work with some decorative accessories). Failing that, you can join two single dry-lining boxes together with a small wooden spacer so that the accessories butt up together neatly; slightly faffy, but have done it myself a few times.
You don't need to join two 1g dry lining boxes. You can buy a dual (2 x 1g) box.
@@gadgetman36 indeed, yes - as I noted in my comment ! But sometimes they won’t suit decorative accessories!
That radiator OMG. - brilliant 🙈😁
I always go with “hire the person , train them to do the work “ hasn’t failed me yet !
Also if you hire very experienced people it's likely that all you will ever hear is "oh, at my old place we didn't do it like that, we did it like this" and finding that they're basically completely disregarding everything you say and doing things however they like... think of a 25 year old chef trying to tell 65 year old nana how to cook roast potatoes... "NOPE I've always done it like this, it's the best way and I'm not gonna change it now" lmao 😅
@@Camberwell86 It's a balance.. Sometimes you hired the person for the improvements they bring; but yes nothing worse then hearing "That's not how I did it" lol
Hi Tom great content, just something to bare in mind with some of these budget fittings is that they don’t always have a UGR
Its like watching a new season of top gear ( However Electricians in action! ) superb top notch content ! One day this will be on Netflix or Amazon prime lol
I appreciate that a lot mate!
@@thomasnagy Mate I really miss the intro… Please bring it back, doesn’t need to be in every video but every now and again just surprise us with the good old intro… I’m sure the other Original followers like myself would really love you for it !! But you know we’d still love you anyway mate but still, please add the good old intro every now and again 😜
Forklift batteries are designed to be changed. Some places run forklifts 24/7 so when the battery is flat, you switch it for another battery. This is why they are unpluggable. Some forklift batteries can be plugged into the charger without opening up the battery cover. Still is one manufacturer that comes to mind.
Also, you are supposed to top up the water in the batteries daily as well. You need access to the cells to do this, although some manufacturers have a quick release fitting on the charging lead so the water is topped up when you plug it into the charger.
Hi forklift battery's a 72V 480ah someone forgot to lift the seat cover up for the gases to escape. next morning seat was by the side of truck, gas had exploded sent the steal battery cover with the seat attached 8M up smashed a hole in the roof. Just glad no one was sat on it.
I love stuff like that radiator , when the game is trying to work out exactly what was going through the head of the person who would do something like that.
Dont label up cable like that , just patch them all in to the panel and re label after , saves loads of time.
Room that size , 4 APs One in each corner. But please dont do direct runs like that , put a socket in the celling and put a patch cable. You are not supposed to put sloid cable into glass ends like that. Its also better for servicing when its time to upgrade the AP.
When i worked for a council doing cctv, fire alarms, emergency lighting etc when working in the civic centre, the ceiling was very similar, it had a little lip on each panel that would slide into, no lock, it meant get it wrong and it would fall, taking all other ceiling panels with it. This was so bad that you could only work on the ceilings when there was nobody in at the weekends
I have seen it before with the half radiator but usually its landlords halving all the rooms to get as many tenants in as possible regardless of rads windows etc. Same with a wall splitting a large window and its clearly one large room split into two.
Only Mr. Nagy would end a video lying on a hammock hanging off of a bucket truck, love it 😂😂😂👌
Regarding the forklift. That battery setup looks exactly the same as the 2 in my workshop. They are not maintenance free batteries and have to be checked/topped up after every charge. I believe they are also a lead acid battery which shouldnt be charged in enclosed spaces (?).
I'm sure it comes down to cost, and when these were first installed Lithium batteries cost an arm and a leg? It might also be max current draw and Lithium can't deliver.
Someone more or less qualified then me knows more I'm sure. Just my 2 cents from the Land Down Under.
Definitely agree with your idea of taking someone on and helping them. I think they would more than likely stay with the business also because of your kind attitude. Do it nagy
In australia we have plates for swithces, dimmers etc that range from 1 gange to 6 gangall in an approx 125x85mm. YOu can also get blanks to cover up any extra holes and you can pull switch mechs out and put them straigh into a new plate making it nice and easy to add and extra switch (assuming there is space behind it)
Another great video I've been watching you for a long time and lately I've been thinking about starting my own company the company I work for does not looks so secure as used to in the past. Your inspiration to electricians and I quite enjoy watching your videos be safe and have a great day
With the tone and probe you can touch the 2 wires together to short it out making the tone stop so you can confirm the cable
10:36 is there anything in the regs that stops you mounting a socket upside-down?
I think, that they do the forklift charging designs because there can be gasses etc coming from the batteries when charging, and this forces you to have it open, not 100% sure tho
Lead acid batteries need ventilation when charging and are a pain to charge take a full day to charge, places like screw fix have a battery room loads of ventilation and shelves for charging batteries to sit on, you swap your battery and off you go.
Server rooms are usually restricted because of sensitive info on the servers, and the importance of keeping servers online. They could let you in escorted, but that's a huge waste of the escorts time. Cable order is important for equipment interoperability. The Type B wiring standard is the most common, you might find Type A in US government installs. Good call on the service loops! Second access point for redundancy!
That and change control.
wait... ferrules and cutting the PE longer is an option? here in germany its mandatory. But therefore we don´t have to fit a 30mA RCD above 32A as its either industrial equipment or will likely be sub-distributed. btw, you can´t just change the pinout of an RJ45. It´s a twisted pair wire for capacitance reasons, so splitting a "signal"pair across "wire"pairs impacts performance. It won´t affect you if you are only pushing 100mbits, but 10gbits on a CAt.7 will have problems.
You have seen the light…… it is at the top of pole next to a road
I would have thought being in a bucket while it is pissing down in February around 4pm when the day seems to go on forever a house rewire with many pubes may be seem bliss? 😉
They make push button switches that look like dimmers. You unscrew the dimmer from the face plate and replace with the push button. Had exactly this in my old house. It wastes a dimmer module but probably cheaper than grid.
