During my rewire, I plan to move my consumer unit to a new position. Currently, it is in a room with a concrete floor, I propose to move it to allow me to get cables into the crawlspace easier.
My supply is an overhead TT supply. Would it be acceptable to simply run 25mm sqr metre tails from the metre in the old position to the new consumer unit, or would I have to contact the power company to move the metre beside the consumer unit?
Also, is it fine to have earth rods driven from the crawlspace, rather than have them taken outside? And must I use a "whole-house" RCD, if I can get the earth fault loop impedance low enough?
And, is it acceptable to use a flush consumer unit in domestic situations, as it'd help keep everything neat?
And, is it acceptable to run cables in the crawl space without clipping them to the joists, or running them through the joists?
Finally, where the cables leave the consumer unit, do the cable grouping de-rating factors take effect for 1-2metres down the wall?
