Hi all. An electrician when inserting a new Meter noticed that my consumer box did not have a RCB in it. He advised me to remove the red isolation switch and replace it with a RCD. Is this correct or do I need both in situ.The consumer box is a GE 8 way. (Not split). I purchase the RCD 80a 30mA
but my builder handyman says their is not enough room to put all the wires in.
Any advise would be grateful.
Thank you in advance. :)
