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?
When connecting a shower does the circuit protective device have to provide overload protection for the cable?
If only the shower is connected is it not possible that the circuit protective device could be rated at 40, 45 or 50 amps with a 6.0 mm twin and earth cable?
