A friend has his electric hob connected to his cooker switch and the electric oven running off of a 13amp plug. He wants to get rid of the electric oven and get a new one that specifies that it must have a fixed power supply (presumably a cooker switch). If the cooker switch has the spare capacity, can we just use a heavy duty junction box to run both appliances from the same cooker switch? Also, this being a kitchen, does the work have to be done by a certified electician?
Thanks for any advice.
Brendan.
