I've had some works done, where the electrician pulled the main fuse, and connected in a new fuse box off an existing Henley block.
There will be further works to remove the old fuse box once the first floor of the house has been refurbished, so will need to be able to isolate the henley block to remove redundant tails.
For info, i currently have three consumer units - one rewireable, one with mcb's and a main RCD in a plastic box, and the new one split RCD, with mcb's in a metal box.
In the future, i'll be looking at having the rewireable and plastic units removed and possibly a new metal one installed in another part of the house (loft).
I have called Npower to arrange to have the economy 7 meter removed and replaced with a standard one, question is will they install an isolator at the same time? Should i have one available so they can fit it? or would they fit their own? if i have one available is there a certain standard it must meet or is any mains (100A) isolator suitable?
