Evening all,

Does anyone now what the correct arrangement for a temp building supply is these days. I am just about to start first fix a new build and am going to have to provide temp supply .

Dno can then connect to the switch fuse /dp isolator etc. One of my colleagues suggested that they now would
Like an s type rcd before the consumer unit as it is a TT. Does anyone know what they like these days as I have tried to get in contact with power networks but I am still waiting for a reply

up front RCD 100ma S type, then into consumer unit 30ma RCD protection at that point, earth rod & tested with results would be good.

3 phase definitely wont connect you without the 100ma trip
