[email protected]hi lads just noticed the post I do have a digital form of the proper candidate pack for the nvq3 please pm me with your email address if you want it thanks...I must point out this pack is blank and for your own use to build your portfolio
Cheers Buzz, I'll check that out.read first and work out how you are going to install it simples .
Cheers Tim, thanks for the info, very clear thank you.Not necessarily. See below.
You need to check whether it is looped supply. If so, stop, and apply to connect.
You need to know existing max demand. If the house routinely pulls more than 60 amps (and it has an 80 or 100 amp service fuse) then stop, and apply to connect..
Otherwise you can crack on and install a charger that will throttle the charger if the grid limit exceeds 60 amps, and then tell the DNO you've done it.
Choosing a charge point that has built in double pole RCD protection including 6ma DC leakage protection makes this simple as at the CU it can just be an MCB in an existing consumer unit and armoured cable (so impact protection rules are met).
You'll need a CT clamp around the meter tails, so will need data cable to the charger too, or use one of the products such as EV ultra that has data within it.
Assuming it's TNCS earthing, you basically have a choice between isolating the earth at the charger and sticking an earth rod in, or connecting the CPC as usual and using a charger with PEN fault protection.
A PEN fault is when the combined Neutral and Earth supply conductor get's broken. This can create a very dangerous condition where all metalwork becomes live, and a person completes the circuit to earth. It's generally not so serious inside a house (vast simplification) but as cars live outside, it would obviously be pretty lethal to have a car body at a potential of 230v. Hence the PEN fault protection issue.
I've not done many of them myself but believe the above summarises most of the pertinent points.
Hi mate do you still have the copy thanksI tried the link and downloaded a 206 page PDF, is this all of it?? this alone is a great help thanks so much!!!!
