I want to fit an RCBO in my consumer unit and because I'm using 16mm wire because it is a 10.5Kw shower with a long length of cable. I forsee some peroblems manovering the cable ends. I want to disconnect the suply completely from the consumer unit, however I may not get the job done straight...
I have an RCBO to install in my Consumer Unit to run my electric shower. Should it be in the busbar that is protected by the original RCB, i.e the rail that supplies the sockets and cooker or should it be in the busbar that supplies the lights etc.
