Thanks for another interesting video lads!
Cheers Jim
Have to say I would take the fly lead straight through the wall and connect in the Wiska box on the inside. Neater and out of the weather.
Yeah so would we. But customer is always right and this is how they wanted it.
@@electrician247 In this case the customer is obviously wrong. I can't think of ANY reason why the install wouldn't look neater with the connection box on the inside of the garage. Maybe the customer prefers to look at a nice neat interior garage rather than an untidy exterior wall!
Will be looking to have an EV charger installed myself in a couple of months, so this video has been useful to understand the process. I have a similar CU, but I'm seriously thinking about having it upgraded (it is 10 years old) to use RCBO's and surge protection. Not sure I would want the EV charger potentially tripping a number of circuits on the new Type A RCD.
@@paulhill9132 you can no longer install EV equipment on shared RCDs due to regulation changes. I would say the customer has different wants/tastes than yourself rather than they are wrong. The customer is always right. I would always encourage updating older switchgear to modern standards. You also have the option of a small additonal EV consumer unit with SPD integration. It doesnt hurt even if the EVSE chargers such as the product shown here have both technolgies built in. I would consult a local reputable installer for advice to help fill in the blanks for you.
Hi Mark, good videos!
would the clamp for the CT be able to go to the Live going in to the Main fuse feeding whichever side of the split board that the EV charger is installed? Inside the DB rather than in the meter box?
Just getting a level should never be a problem, even for a spark. I`d be watching this young guy like a hawk.
You would be wasting your time. But nice of you to knock a young kid out doing the do from the comfort of your keyboard.
@@electrician247 No mate all to do with proper training, being a `time served tradesman` and common sense, nothing else.
@@TheMilford99 as is Matthew. But thanks for the unkind assessment from watching a single video. They maybe didn't teach you that during your time served. But you won't ever catch Mattie critiquing someone on the Internet he doesn't know. Peace.
Thank you.
Thanks
Today,, we install EV charge points
Tomorrow (plus 10 years) ,, we are hooking up 3 phase
I fit black screws myself on the hyper volt holsters, it’s lot nicer on the eye👌 haven’t installed an ohme yet but there’s one in the unit waiting to be installed. Hello from Ireland 🇮🇪
We do the same. Makes for a nicer finish I think
@@electrician247 It's called finesse Mark.
Nice video, thanks. Just about to install an Ohme for the first time, they look really neat units.
Is the cable from the Wiska to the Ohme ev ultra? I can’t see the cat5 there outside the JB so assuming you just used a short length of ev ultra (or similar) between JB & Ohme?
Sorry, since realised the pro has a fixed flying lead, but the epod doesn’t. So in effect yes the cable between the jb and the ohme is an ev ultra type integrated cable. I guess that’s the neatest way to do it for the epod too without a fox flying lead.
It's supplied like that. Cable comes with the ohme but yes carries rs485 and power
@@electrician247 yes I see that now, I hadn’t looked at the pro until now. Thanks. Keep up the good work
It would of been neater to install the JB off the charge point inside, there’s more than enough cable to have run it inside and do the connection there. Best to keep JB,s inside where possible.
I don't disagree but the customer gets what they want and as discussed in the video was worried about hitting it with ride on mower.
Nothing wrong at all with using IP JBs outside installed by professionals. It's what they are for.
@@electrician247 Nice video, shame about the JB on the outside, makes it look a bit messy but if that's what the customer wanted fair enough. What about all the other stuff on the walls he could crash into! ;-)
@@EssKayTee1 with the ride on mower he parks there? The concern for someone else’s wants is bizarre bordering embarrassing 😂😂😂
Nothing as strange as people on the internet it seems lol
Hi Mark, I don't suppose you would have the model number for the CT clamp would you ??? 🙂 Pleeeeeeease
How did you get round the ADMD on the application form to the DNO? My DNO says they won't authorise an EV charger unless it's no more than the cut out fuse.
You have to keep within your service supply limits. Load limiting is an option and most DNOs will accept this. Most charge points have this built in now. That said if you have a 100A head likely to be fine unless you have an especially high consumption
Cheers for your reply. I'll have a chat with the DNO tomorrow. I specifically went with the Ohme Home Pro for that reason. The ADMD came out over 200A on one ive just looked at😱😱
Keep up the good work and videos👍
Good job Mark, Matt likes the one glove approach? I just try to get the majority of the screws and anchors straight and level, and if one is off, no big deal, the other screws keep it level.
Agree John. I will have to ask him why only 1 glove 🤭
I misplaced my other glove😂
@@xmoodymattiex let's not get started on the things you have misplaced over the years 🤣
I had the same EV charger fitted and didn’t want the junction box on outside of my garage, the main cable had to go in to a dug out 30 metre trench from outside main house supply due to distance and not wanting it clipped along bottom of my house. I was having the EV charger put on centre brick post between a double garage but can understand why they couldn’t do it . Here you could have avoided having junction box on outside garage wall and kept inside from where you placed it , you could have made a U turn with supply cable was there any reason you didn’t ?.
Yes the customer didn't want the junction box in the garage as was worried they would bump into it with stored ride on mower. Horses for courses and the customer is always right.
When the Ohme Pro is fully fitted how far will the cable stretch to? Yes, it says 5 metres but for a comfortable reach I would really need just over 5 metres rather than just under when allowing for a vertical drop against the wall. The optional 8 metre length would probably be too much and I presume it has to be fully unwound when in use.
Also, can it be installed alongside the meter cupboard (100A) with an additional EV consumer unit rather than through the wall and into the house to reach the main consumer unit?
I would advise against external consumer units the lead is exactly 5m no stretch or play in it.
nice video, he didn't use the wall plugs for the screws, would it be strong?
Concrete fixings that self cut the brick. Much stronger than plugs ain’t ever coming off the wall lol
Hi, I'm looking at different ev chargers at the moment, I have a TT earth on my system, does this matter? thanks
I’m looking to install this charger but will need to extend the 4G antenna due to poor signal. Do you know if this is possible, don’t mind having to crack it open if need be. Thanks.
I'm not sure tbh.
Good video.. With regards to connection inside the outside JB, whats the best to use for this? Wago 221-613s? Or crimps?
Either works mate tbh. 👌
Hmm, was also thinking with regards to this charger, I guess you’ve run shielded Cat5e cable and earthed the drain wire? As it’s in the same JB, or would you not earth the shielding?
@@jimborland5412 just need ti make sure the cable is rated for the maximum voltage present which it is. You can earth the screen if you wish but not required in this application.
@@electrician247 thanks Mark, but on screened Cat5e, the sheath is rated to 300 volts but this is stripped off at the JB on a Ohme, and the twisted pairs insulation isn’t rated to this, it is much lower voltage rating? If there was a fault in JB, aka loose line connection, mains voltage could touch the twisted pair, or does the sheath being rated to 300/600 volts cover it? Sorry for all questions, EV is a bit of a minefield haha.
@@jimborland5412 You have to get specific cable for the job. This cable is rated to carry 300V not just the insulation. With the EV ultra style cables they all approach it differently. Procell/Eland have individual screened cores while doncaster cables screen only the whole bunch as one. Great question though
You wouldn't happen to know the wall bracket mounting hole spacing/dimensions for this charger? I want to make a mounting post for it.
Sorry I don't know that. I would drop ohme a message on the website of socials. I am sure they will help you out. Thanks
Why not use the length of cable supplied to get in side the garage, then terminate in side the garage.
On to a different question I have a BP pulse charger installed how much would need to be changed to install a ohme pro instead?
Read the comments and contact a local electrician to answer question 2. Thanks
Great video as always Mark.
Can I just check something you said about using the main switch as the point of isolation?
On my EV course I was always told you need a double pole RCBO. Are we saying that’s incorrect if the main switch complied with reg 537.2
In terms of RCD protection both poles need to open. In terms of safe isolation to work that can be achieved via the main switch of any install or by removing neutral links.
Note this install was pre amd2 of bs7671 and we would now be fitting rcbos rather than a shared RCD
@@electrician247 fab thanks for the reply Mark so on that split load board. The RCD’s were dual pole hence it complied at the time.
Perfect that makes sense. 👍
I would have put the long lead plug cable at the other side of the ohme box the car side and is the JB not better fitted inside the garage for the weather cheers
Customer choice. We all like different things and have different wants. Who knew
Regards installing Ohme pro ev do you still require surge protection device on this issue
Yes
Hi. Can I ask what the ethernet cable is used for?
Ct load monitoring
Surprised the junction box isn’t on the inside of garage. Just a thought. Saves bend radius problems though I guess
It's always an option but not necessary. In this case lots of stuff stored internally so keeping it external made sense. Either or, same result.
Personally I don't like plastic boxes/switches/sockets in garages. Too much risk of damage from all the crap people keep in them.
Is your Cat5e cable rated to the highest voltage present?
Covered in lots of videos already. But of course. Basics.
@@electrician247ah right cool, what brand is that and where from for Cat5e that’s rated to mains voltage? Don’t see many that are rated to this, normally use EV ultra.
its says nice job, i would ask the electrician to redo the supply cable and box to have a bottom entry or put a loop in the cable , rain will at the moment hit the cable and run into the junction box !!!
Ip68 cable gland, side entry, professionally done, 1 year post install, dry as a bone. Short story your wrong and thats okay. No need to waste the clients job redoing what is a nice job.
How do you connect the cat cable in the JB and at the consumer unit and what is it for
Load monitoring. Your electrician will know how to install it
Can you wire up an ohme to be fed by the house solar panels as well as the electricity from the meter
No they are not solar compatible.
@@rufus_6946 According to Ohme it is solar compatible
Now we have to use Double Pole or Single Pole RCBO with Switched Neutral and SPD upstream the EV Charger installation.
We know. Funny thing time and regs. Once we never even had RCDs 🤭
Great video...
I have an Ohme Home charger and it's been giving me lots of trouble. And now that Ohme said the log charger (installed less than 9 months ago) shows some faults, they want me to pay for the replacement.
I had it connected it to the car and to the Agile Octopus tariff and saw that it often ignores it and charges the battery to 100% at whatever price.
A reboot fixes it, but when I contacted Ohme, they tend to easily blame it on the mobile network and on the car manufacturer API. But... the same mobile network works for the car app and how could an API issue result in the Ohme app showing different battery charge levels on different tabs at the same time?
My verdict: Unreliable charger
All of the API link ups for EV and PV are the same. Glitchy at best. I manually control mine.
Was that a 6mm or 10mm cable mate?
To long ago to remember tbh lol!
Couldn't the 1M ohme tail go through the wall with the junction box inside the garage then it'sneater and out the weather? ?
Read the prior comments anything can be done. Perspective and perception
cant see how you have made off the armoured cable ? seems like you didnt gland it off ?
The drama and mystery of the Internet 🤭. This isn't a step by step and parts are deliberately missed out so as not to instruct. Hard balance as get complaints both ways lol
@@electrician247 sure 😉
@stevekennoy5576 trust is something hard won but if you seriously believe this isn't glanded off I can't help you.
Perhaps judging others by your standards maybe?
The truth is I get complaints often for showing to much instruction and at others not enough detail.
Doing www.apprentice121.co.uk leaves me a bit stuck sometimes as I want to help trainee electricians but equally don't want to enable have a go diyers. Which is why the EV videos often leave elements outside the video.
If you want to make an instructional video start to finish or already have point me at it and I will give you support and share it further.
If you want to make more sly and underhand insinuations perhaps reevaluate things. Your wrong
@@electrician247 sure 😂
@@SsKk558 mate you just got owned and you dont even know it lol. Go and listen to around 11:50 on the video and you will understand why the "SWA" isnt a factor pahahahaha.
Its NYY lol.
So back at you my friend lol. Sure......
Boxes never fix straight,, that’s why Orbix found a market
Why didn't they put the junction box inside the wall. Run the cable from the Ohme through the wall not the feed cable.
Read the prior comments and watch the video fully. Customer didn't want it that way due to ride on mower stored in the garage area. Not that it makes a bit of difference anyway.
For the CT Clamp, which cable is the positive {+} ? Black or grey?
I can't be 100% as can't remember but black is generally positive and white negative on CTs.
Pretty sure they aren't polarity sensitive
@@Adam-Electrical this is true to a point. On all CTs tbh. If you swap the cores over you also need to swap the direction the CT points.
@electrician247 I did find it odd. When we do commercial energy monitoring if we've got the cores the wrong way around to the meter we will get negative readings.
Since installing the ohme chargers it doesn't seem to matter which around you put the cores or the cts it seems to work. So I'm not sure if the software in the charger will recognise the negative reading and change it to a positive reading. Works both ways I guess. Might give ohme a ring cause if that's the case then its very clever for what they cost
@@Adam-Electrical Ohme have confirmed that is doesn't matter which way round the CT clamp is installed.
I don't think I have known it mention the default if the CT clamp is disconnected even on Jordan's channel.
Yep the ohme defaults to a safe state. Nice touch I think
Why did you not put that ugly junction box on the outside?
Ohme chargers always need the junction box and that is where the customer wanted it.
Have a great day
@@electrician247 Thanks for the explanation, Strange choice, but each to there own, sorry didn’t see the answer to that observation apologies 😊
I'll be giving that a miss. The connector hook and cable looks an absolute mess.
The beauty of choice. I would advise speaking with a reputable local installer before making any rash decisions. Have a great day
Ohme is pronounced Ohm ee, not Ohm!
You know what I meant though. 🤣🤣🤣.
Says who and does it matter 😊
