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)?

    Bear in mind that a single socket could have a 2-way unfused 'cube' adaptor plugged into it, effectively turning it into a double socket, where 20A may flow (but never 26A, because that never happens, because Reasons),




    Being a little devilish ...


    Double socket-outlets to BS 1363-2 are now (to the current standards) rated at 13 A. Single socket-outlets are also rated 13 A.


    This leads to the question "Is it OK for a tumble dryer and a washing machine to be simultaneously plugged into a double socket-outlet?"

    Best not to have a washing machine and a tumble drier on the same double 13 Amp. socket, as I have found recently when that situation caused the failure of the double socket due to a burn out of the switches.
