I need to replace a rewirable consumer unit but there is not enough room to fit a new metal unit, what are my options?
What size is the space available, how many circuits you covering,domestic I presume. A bit vague with your info.
It is a 12 way Wylex board existing but there is no physical possibility of fitting a amendment 3 box in the space available.
It's as niggled me for years domestic CU & their shape, a lot to be said for the commerical distubution board shape for domestic CU use. Done jobs years ago, were a narrow width CU would make job easier due to restricted space.
