Installing a microwave oven that has a 16amp fuse rating?

Emmanuel Yohannes

Hi All,

I had my kitchen re-wired and there was something that I failed to pick up which has caused me problems so far. Basically, I have a Zanussi ZVENM6X1 microwave oven that has a fuse rating of 16amp, but the problem is that I hadn't put it on its own dedicated 16amp circuit breaker, there is only the single socket outlets available but I don't think its safe and I don't think I can hard-wire the appliance to a 13amp plugtop. I had a few suggestions from others telling me to hard-wire the appliance to a Fused connection unit and then put a 16amp fuse in the FCU. Is this a feasible way to do it, or can there be another way to hard-wire the appliance without having to chase and introduce a new cable from a newly put 16amp circuit breaker from the board

Many Thanks

    Curiously if you got back a few editions of the regs, the options included a 15A or 16A circuit breaker as an alternative to a 13A fuse to create a fused spur from a ring circuit. (I did actually use that option once to be able to feed a socket plus other equipment from an existing spur).

    Maybe, but that is simply because 13A is the highest rated fuse that can be used in an FCU.

    A 2.5mm² spur (method C) could, CCC-wise, theoretically be protected by a 25A MCB  or -

    just use 4mm² cable for the spur like a branch from a 32A radial.

    Yes, I know all the pitfalls previously mentioned with regard to a ring circuit.

    It is time the UK ring circuit (with its regulation still written for 30A BS3036 fuses) was done away with - there really is no need for it since the introduction of MCBs.
