I want to cut about 2" of the top of the board that holds an electricity meter and the company fuse. To do this I need to remove the board. I can see how to unscrew the meter, but there are no visible screws for the company fuse. Will these become visible if I remove the fuse itself, and can they be safely removed to release the fuse holder from the board?
At the moment the electric oven and hob are fed from a 30 amp fuse using what I would call a thick cable.
I have found that MK sell a consumer unit populated with RCBOs. This has two 32A RCBOs presumably for two ring mains and one 40A RCBO which I assume is intended for an oven and hob (cooker).
If I want to use a 40A RCBO what is the minimum size of cable I need to have to be sure that it is good for the 40A.
