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)?

    That's interesting - I've never come across a 13A grid switch - usually they're 5/6A, or 20A. 13A markings on BS 1363 accessories yes, but not grid. I wonder if the switch element had been re-purposed from a FCU (some brands seem to make them up from grid-like components).
