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?
perspicacious: The simple issue was an existing circuit. A shower circuit. It had already been installed, presumably fit for purpose. The Ib was assessed when it was installed diversity applied, that formed the type/rating of OCPD and the cable. So In>=Ib.
