Grid switch ratings enquiry

Farmboy
Had an interesting chat with a tech dept this afternoon after coming across some grid switches in a domestic kitchen.


Four grid switches (sharing a common backbox) are each fed via their own 16A cb's, and each feeds 1G sockets (for a cooker hood, fridge freezer, etc). Ignoring the cable sizes (the focus being on the grid switches), given the 13A plug fuses limits the loads in each cct, would you have the current rating of the grid switches equal to or higher than the 16A cb's (e.g. 20A), or lower (but equal to or higher than the socket rating e.g. 13A/14A)?

    Yes commercial and industrial are totally different things.


    I was having a nice Indian meal with a friend recently. The service was excellent and the food wonderful. Towards the end of the meal the restaurant become fuller with diners. A waiter came over and apologised as he had to get behind my seated dining companion to access a cupboard door. He opened the door and reset a M.C.B. Evidently a new piece of kitchen equipment had caused yet another overload. An overloaded ring no doubt. The consumer units were at the very front of the restaurant and the kitchen at the very back, so a sparks will have an interesting job in running a new cable.
