I have a Wylex spilt load CU (from Screwfix) fitted with a 63A RCD, what I would like to know is this:- Is this device a 63A breaker as well as being an RCD, or is the 63A merely a maximum current rating for this device.
I want to fit 2 electric showers, 9.5kW each on seperate breakers but on the RCD half of the board, what will happen if both showers are on at the same time ? Will the 63A RCD trip, or will the 63A RCD smoke ??
I fully intend replacing the 63A RCD with a 100A RCD in due course, but am curious in the meantime.
Cheers,
Paul.
