Members any questions on anything please ask ... if you would like to talk with me direct , WhatsApp etc , that is available on the memberships. Please note that hand to foot resistance is higher than hand to hand resistance with shoes and socks on and floor type also plays a factor ..

Looks like a bodge and leg it⚡😳
So you will use an insulated compression gland instead of the brass swa gland for the incoming armoured supply cable or just a brass compression gland that is not in contact with the armouring?
40mm plastic compression
@@Mainly_Electrical Thanks for the quick reply 👍.
Anytime thanks for tuning in Rich
What would you do about that first one, put a quote in to fix the work, an estimate?
Rewired this place in the end mate .. well beyond repair it was
Looks like it was TN-S then some years of "something" happened and they added a newer head after the original and it's all TN-C-S now. I don't think this is a new-build property. Lol. Maybe a flat conversion ?
C3!
Very clever bloke, fair play to you mate . It’s all well over my head this
@@eddiepearson9423 we're getting there Ed... appreciate the comment thanks 👌
Eart CSA calcs
Looking forward to this classroom skooling Mainly. Great way to learn especially when you put the question up first. 👍👍
Morning B .. looking forward to it 👍
Current runs round circuits not voltage
Functional test, failed. Must be replaced!
How caught out with this yesterday
Thank you sir for sharing this 🙏
Welcome ibzy 👌⚡️
Right, thats it! Im getting membership!
Different level video, thank you.
Really considering joining
Tns. But maybe im missing something. It doesn't look earthed at all....... Unless the MI is the incoming power.
Another brilliant video mate. Haven't thought about the safe touch voltage for a while! like you said,we all tend to go for the zappi etc.
Cheers Carl hope all is well your end ❤️
BG…a Builder’s board for a builder install
(35/63) ÷2 = 0.27 max for c63 So no 👉
Still see this type of lash up in London, madness where do our up dated amended regs come in 🤠😎👍 keep up the good work
No due to the low impedance, refer to the regs the formula is there.
Cut outs and fuseboard need being inside a cupboard for any arcing and the paint spraying igniting
Supplier’s paying for whatever that pyro’s connected to 😂
Yah the tails arent identified brown & blue - shocking 😂😂
Wheres peppercorn sauce y'all 😂
do love a bit of peppercorn but she can't remember everything mate 🙄😂
Reading trough the load, 👌
🤙❤️
Very nice explanation and nice to see people are learning from all this. It should wise people up as to why it's so critically important to have correct bonding in wet areas with the much reduced body resistance.
Your videos are quality mate
Appreciate it mate thanks for tuning in 👌
Doesn't look like pyro to me
Looks fair mate, enjoy 😋
Best cut by a stretch for me, Unreal Dom
Enjoy the meal
Quality information.⚡Thankyou👊
No probs martin thank you 🤝
whiteboard in a classroom, been a while since i looked at one of those
😅 you keeping well retro all good your end ?
@@Mainly_Electrical All good here mate. Getting stuck into repainting the hallway today. Quite a lot to it, torch out and skim all the bumps, then fill the dings. Same as with with all things, the effort put in directly proportional to the end results.
Absolutely brilliant video, thanks mate!
All good mate thanks for tuning in 👌
That mic is blowing my mind 😂
Why do we not just put pen fault protection at the source for new pme installations.?
Issues with under/over voltage knocking the whole house off .. mainly over voltage
@@Mainly_Electrical ah fair play . The site we are based at is 250v so you could possibly get nuisance tripping
@@darrenjeffes7030exactly that .. I often go to property's at 3 4 5 am and the voltage is cracking on for 255 as nothings in use
Very informative good video
Thanks Derek 👍
What about if ground conditions change as in Summer when it dries out and the Earth loop impedance increases?
Makes very little difference in places like this
Wow wow wow 10/10
Cheers G ❤️
I put the measured reading on verification of test results next to my calculated ?
I put the calculated end to end reading on am2s test sheet waiting back for my result will that fail me ?
What ring r1r2 x 4 for calculating end to ends ?
@@Mainly_Electrical so on the test sheet for R1+R2 result I put the r1 and r2 end to ends /4 but should of been the highest measurment? Would I fail on that because if I had put the measured value wouldn’t of complied with Zs for the circuit
The 1 one is to do with calculating the size of earthing conductors must meet Regulation 543.1.3 Adiabatic Equation 👍
Nice adi 👌
I presume it’s a 60898, so max dis for a TN, @5s,C63 for a distribution circuit,0.35. So no, doesn’t comply, correct me if I’m wrong 👍🏻
Correct 👍
218.5 divide by the 63x10 = 0.34 than x 0.80 final answer is 0.27ohms.
Why calculate with 218.5 ok so 230 minus 5% ? I guess because that would be worse case ? Why put a c curve on distribution or sub man though and who gave a mouse the enclosure to chew on !
On Amendament Number 3 17 edition Start changing to the way measurement values of Zs is to assessed The value as 0.95 added to a his Table in the addition the formulae in Appendix 3 and 14 with explanation Note it allows worst -case conditions 👍
