Two high-power appliances on a single 40A RCD
Former Community Member
I have an electric shower installed on a 40A RCD, in a room adjacent to my kitchen. The shower is only used in an emergency - i.e. when our gas boiler is unable to provide hot water to our main bathroom. I would like to take a spur from this 40A connection to use for a new double oven, which is rated at 32A. Can anyone advise on a safe and legal way to do this, ensuring that only one of the two appliances can be connected at any one time?
Yes I have a 40A circuit breaker in the consumer unit. Presumably an MCB changeover switch is something which sits in the consumer unit? I would actually need a switch downstream of that - i.e. in the kitchen/bathroom - as I would want to switch the supply between two appliances on the same circuit?
A 40 Amp M.C.B. is a miniature circuit breaker. You referred to a 40 Amp R.C.D. I assumed that you meant an M.C.B.
The changeover switch will not be located in the consumer unit, it is too big. It will be installed downstream of the origin of the circuit.
