I'm formulating my plans for May workshop (20' x 20‘ double garage), and have some questions regarding 16amp sockets.
The garage power is fed from the main house CU and 32A MCB with SWA cable. There is a second CU in the garage with plenty of spare breaker slots and also a 30mA trip.
I'm getting my electrician out to do some wiring in our bathroom and would
Inke him to install two 16amp sockets and isolators for me. My question is, should I have these done on a ring with a 32A type C breaker, or two separate radial circuits with smaller breakers?
There are also 4 double sockets (not enough), fed on a 20A radial, think there was only one socket when it was built. Want to have a few more installed. Should I have a 32A ring installed or a couple of 20A radial circuits. In the event of an overload, I don't want the MCB to disconnect in the house before the garage one.
I want to fit all the boxes and conduit ahead of the electrician - he's a good sparky, but can't install anything level or plumb
Cheers in advance
