Really helpful king of person. Thanks.
Two quotes. You don't know what you don't know.
And don't judge someone on their worst day to you on your best.
Now rather than criticising either help my understanding or go away. You hold the 2396 so you are perfectly capable of explaining.
I...
TJ Anderson thanks for response. My response you highlighted doesn't read well. I will try to explain better for discussion. That's what it is discussion not criticism.
When meter tails are over 3m an isolator is normally needed to satisfy the dno.
If the tails were split with say swa cable...
No not at all. But when your only option is the meter cupboard space you start to have issues. My concern was for future car charging capacity when he has two cars but since having looked at the xlpe cable I will go for 16mm. 10mm would most probably be ok but why ---- about for 20 pound...
15 meters about. I understand its large but as time goes by probably not large enough when.people have two electric cars. For few pounds seems better to be safe than sorry. I changed size because 25 will be a nightmare to terminate.
Obviously it needs a cpc it will be a TT?
Car charger outside and all car chargers can go on TT but not all can go on a pme due to issues with breaks in neutral conductor potentially causing the car to become live.
No extraneous conductive parts but floor is concrete therefore my understanding...
Hi thanks for reply.
I don't fully understand your isolator point. The current tails are 15 hence they are on the isolator seen in the picture. They do not require fused switch? So why would my swa require one.
I see your point but not entirely sure I agree otherwise all meter tails would...
Hi ok here we go.
Friend has asked if can rewire his garage as he is turning it into a gym. I said ok no problem.
He the put the spanner in. Ok I want
1 circuit for a car charger. 7.4kw.
2 x 3kw heaters
1 x ring main for gym equipment. From what i can tell running machine is most power...

Ok. I went and purchased a clamp meter today. For a little test I clamped my main live and neutral 10ma. Out of interest I clamped the main earth. Same reading. 10ma.
So I opened up my board and only cable in that I could easily clamp was my alarm cable. So I...
Thanks for reply again. I underatand what you are saying and before today i have never really considered it because i have never clamped a sole main earth.
My conclusion is the leakage is as you say because my RCDs are fully operational. So this 225 to 400ma i think is incoming.
To try to...
I will do. I borrowed it as i didnt have one.
Could you explain with little more detail why if i clamp mine at home either live and neutral or just main earth i get the same 14ma. Trying to improve my understanding.
