My First Post
My existing Consumer Unit has 8 MCBs and the main isolator is an RCD. Off of one of the MCBs is a circuit to the kitchen sockets and there is a spur off of the kitchen ring that goes to the garage. In the garage there is a CU unit with an RCD protecting the load. Along with the garage sockets and lights there is connected all my garden stuff, pond lights spot lights etc. At the moment I have a problem with something in the garden which is tripping not only the garage RCD but the house RCD so when the problem occurs in the garden the whole house goes off.
I know my first job is to change the main house isolator to an MCB and then protect the rest of the supply with dedicated RCDs. However all the CU units I've researched have a split system i.e.. a split unit with typically 2 RCDs protecting 4 MCBs each. If I connected my kitchen ring with the garage spur to one of these split units I would still have the situation where if I had a problem in the garden I would lose half my circuits. So my question is what do I need to do to protect my house with RCDs but protect the garage and garden the same way without losing supply to the house.
