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)?

    The socket-outlets marked "/EV" are tested and rated in the same way, but some tests (breaking capacity, clause 17, and normal operation, clause 18) are carried out at a power factor of 0.6 +0/-0.05 and the number of cycles for the normal operation test, clause 18, has a different number of cycles.
