Hi all. I am after some advice just to allow my planning of a new CU to replace the current setup I have. I know the possible comments that could come about getting a qualified sparkie in, the issue is my go to man is currently on holiday for the next 2.5 weeks and I want to get some planning in place. I am knocking two rooms into one and building regs have to be considered so I cannot do the work myself anyway as itwill have to be certificated etc. I am only after information to satisfy my brain. So if you can give me any guidance I am after is how I can combine the following two CU's into a one new CU. I already have a new 21 way Metal Clad unit with a 63a and 80a RCD. Consumer Unit 1 Running direct off main switch Boiler - 16a MCD Water Heater - 16a MCB Lights Up - 6a MCB Lights Down - 6a MCB Cooker - 32a MCB Running off 63a RCD Shower - 45a MCB Sockets Kitchen - 32a MCB Sockets Ring - 32a MCB Pond - 16a MCB Consumer Unit 2 Running off 40a RCD Sheds - 32a MCB Rear Outdoor Socket - 16a MCB Electric Car Charger - 32a MCB As I say my go to man is away and, yes I could wait until he comes back, I just wanted to understand the layout that would be best.
