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?
Gosh, what a lot of postings since I looked in a few hours ago! ?
What is the design load? From the sound of it, it is not the shower plus the stove - it is the shower or the stove. The householder knows that. However, an emergency shower for when the gas is off does seem to be a great luxury.
I accept that there is a difference between intended maximum load and possible maximum load, and I also appreciate that some form of switch (change over or priority) unequivocally is compliant. However, has anybody mentioned the D word?
Put another way, you have two 40 A showers, and a 40 A cooker on a 100 A supply. Does that break the rules?
My apologies to the OP if this technical discussion is unhelpful. ?
