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)?

    I imagine the electrician will chose a time when the restaurant is not so busy, and he or she can run a submain cable through the dining area to the back, or fit a larger breaker.?

    Commercial electrics has quite different load profiles we ignore at our peril.

    Interestingly Mike, the waiter said that the cable will have to be run above a false suspended ceiling.
