I've just removed our old built-in gas hob and purchased a nice new shiny eclectic ceramic one. After removing the hob and temporarily pulling out the electric oven directly below it, I expected to find a cooker connection unit. Instead there's just a double 13am plug gang/socket? This is connected directly to a nearby cooker dp switch. The manual for the ceramic hob states it should be connected directly the cooker mains. Can I replace the double socket with a cooker connection unit using the cable from the cooker switch?
