Hi. Existing standard blank plate, which I would like to change to an electrical socket to feed a kettle or a toaster for example. The blank plate cable run looks like it feeds two separate electrical outlets. One is used for the ignition only on a gas cooker (via 13 amp plug) the other is used for a cooker extraction hood, again with a 13 amp plug. Is this something that can be done, or could it potentially overload the circuit (if that's the terminology to use)
