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?
Perfectly correct Chris, I would not consider this a long duration. I hinted about current ratings and time earlier and this 25 minutes is not a long duration.
I also do not believe that a 30A switchfuse could "blow off the wall". From experience this takes quite a large supply of 100s of kVA and a direct short with PSSC in the many tens of kA.
