hi im installing a cooker with seperate hob i have a 6mm cable from cu to the cooker ccu, im planning to run a 6mm cable from this too a cooker connection plate connect the hob up from here and then run another 6mm cable from the connection plate to a single socket for the cooker to be connected too so that both hob and cooker can be switched via the main cooker switch but the cooker will have the lower protection it needs, does this sound right?
