I have just installed a new electric shower circuit and light circuit to a bathroom. No space in existing CU so installed extra CU for shower. As per regs new circuits to bathrooms must be on rcds. So I have 63A 30ma main switch, 40A mcb for shower and 6 for light, both circuits under the rcd control. As all circuits should be installed to cause min inconveniance if a fault occurs, would you consider this arangement a min or max inconveniance. When LABC came for the first fix they never had a problem but I have been pondering over it. I could simply just reconect the light back on its old lights up circuit and remove the new mcb, but as an added safety feature I see my way as an acceptable incoveniance. The old way would see the accupier going down the stairs in complete darkness to the CU if a fault occured on the lights up. A fault on the shower would cause the light to go out in the bathroom and visa versa but the rest of the house would still be lit. Should I leave it as it is or disconect new light circuit? LABC inspecting and testing Tuesday so Monday is the crunch day. The cheap option is remove light mcb and have shower only, the expensive option is redo it with RCBOs.
