Just had a new consumer unit fitted it has 5 MCB and 1 RCD the electrician said it is 17th edition but someone has told me it should have 2 RCDs and the MCB should be split between them who is right.
Can a 2 pipe central heating system be split into 2 loops the reason Im asking is at the moment it starts at 22mm then down to 15mm were it has 1 radiator come off then does the rest of the radiators.What i would like to know is if you can add more radiators to the first radiator.
