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 it's an MK Electric 7937S which is an MCB/Residual Current Device I believe? OK so I would have the MCB changeover switch installed in the kitchen as a replacement for the existing on/off wall switch for the supply to the electric shower?
I was told by a kitchen fitter that he was not legally able to put two high power devices on the same circuit, so presumably this would address that issue?
