Hi all,
Testing question for you.
I'm currently testing an existing domestic installation. The wiring is about 20-25 years old.
We have rewired some of the older circuits and added newer circuits too. During my insulation resistance test, over two-thirds of my results were coming out at...
Objective: allow fast charging of EV (22 KW)
DNO cutout has 3 100A fuses, but all 3 turned out to be on the same single phase
How to still obtain 22 kW for fast charging of EVs?
Rotary phase converter? Switched on only when needed?
Other approaches?
Hi
A client wants a EV type 2 charger but she lives in a end of terrace. There is a pathway in front of her house and a front garden but no driveway yet. Can she have one installed?
No Olev grant but I thought you couldn’t if they didn’t have a car driveway to stop a possible trailing lead.
thanks

A plastic conduit is laid under the floor ready for a cable. I want to use 25mm tails rather than armoured. Previously I’ve fitted 100amp SP&N fused switch with 25mm armoured but they are tight to make off in the mains electrical meter box and some providers don’t want you in there box! If you...

Hi all,

The obvious answer is, it's somewhere someone lives. Using that definition however, a hotel could be classed as a dwelling because sometimes people...
