Hello, I want to install a secondary consumer unit so that I can do some outdoor wiring. I'm happy with the technicalities of how to wire from the consumer unit.
But,can anyone tell me in practical terms how to connect the secondary unit to the incoming mains and what parts to use. I thought I would simply be able run some wires from primary CU to the secondary by inserting some new wires into the same terminals as the incoming supply on the primary CU but of course 2 wires this size won't fit into the terminal holes.
Can I fit a terminal box and tap into the incoming wires?
Any help and advice on what parts to use and buy would be greatly appreciated. I am assumming I have to 25mm sq cable for the new consumer unit incoming supply.
How much would it cost apporxiamtely to get the electricity board to come and connect the secondary unit? Thanks.
