Hi guys
Sorry to go over old ground but having read the older posts on sizing the cpc for a 16mm distribution cable I just thought I'd check to see if I've got it.
On one floor of a converted warehouse there are five bedsits, each has a five way board supplying a cooker, lights, a ring and a couple of 20a radials. The building is about 30m long, there is no gas, oil, etc and the water is all new and entirely in plastic. The distribution cable for each one is 16mm T&E with a 6mm cpc.
The main supply hasn't been connected yet so fault current can't be measured for any adiabatic calculations, there is nothing to bond to so there's no need for main bonding within the bedsits or going back to the main board at the entrance to the floor.
They asked me whether they need to upgrade the earth to each bedsit and I don't think that they do.
Am I right or have I missed something?
