Hi just wondered if I could have some advice please without having my head bitten off about having power installed I'm my garage, I have posted on another well known forum and have had allsorts of abuse without actually getting any advice so is this forum for DIY or is it just for " qualified electricians to chat to each other " as I have been told on the other forum !?
Home charge units are 32 amps. The circuit usually is 32A as well, but doesn't have to be - the MCB is for protection of the cable, not the charge unit. Larger ratings of both are possible.I think its more this 40 or 50amp mcb in the main CU and the A type rcd that I'm worrying over that's all
Should do those things - don't assume anything.so basically the electrician will do all the required stuff,
You don't claim the grant, it's done by the OZEV approved installer.The price off the shelf at trade basically works out the same as what it would be if I was to claim the money back
Main switch, 32A MCB EV, 20A RCBO sockets, 6A RCBO lights.smaller CU in garage that has a 40,32,16,6 mcbs and a A Type RCD the 32 for car 16 for sockets and 6 for lights, 40 won't be used
Most manufacturers of EVSEs recommend a 40A device with a 7kW charge point so that it's not running at its nominal rating the whole time.Home charge units are 32 amps. The circuit usually is 32A as well, but doesn't have to be - the MCB is for protection of the cable, not the charge unit. Larger ratings of both are possible.
Type A RCD is the minimum required for most installations, assuming one is actually required at all.
Some charge units may need a particular type of RCD externally, others have it all in the unit.
The cable supplying it may require an RCD depending on the type of cable used, how it's installed and what type of supply the property has got. It may not need any RCD.
