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

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

  • You will not get a 16A fuse in a normal fused spur, you would need a thing like a mini consumer unit to take a 16 A breaker to spur off the ring, and even then it is not a common arrangement. (you might find a smaller version of this sort of thing    or in metal )

    But before rushing off all keen, are the sockets on a ring or radial, and what size is the breaker upstream of them. Be aware that a 'normal' UK ring has a 32A breaker or perhaps in older places a 30A fuse. Kitchen radials however can  20 or even 15A in which case adding a single 16a load leaves nothing much else for other appliances.

    The best way would be a dedicated feed, but some cunning may be needed to arrange it with minimal aggro.

  • It also says "Total electricity loading, W: 3000".

    It is likely just referring to the 16A circuits used in Europe.

    Anyway, any fuse is to protect the cable.

  • well if it is just 3000watts then a 13A plug would just do. depends also if the cable fits mechanically.

  • Please be aware that the ZVENM6X1 is NOT simply a microwave oven: https://www.zanussi.co.uk/kitchen/cooking/compact-built-in-range/compact-oven/zvenm6x1/

    It's a combination grill/oven.

    As such, whilst 3 kW might look like it should be OK on a standard socket-outlet circuit, it really depends what else is on the circuit, and, even if not radial, it could unbalance or overload a ring final circuit.

    Depending on the other loads in the property, this type of appliance may well be best on its own circuit.

    It may also require a local means of isolation in line with certain Devolved National requirements.

  • Anyway, any fuse is to protect the cable.

    Not any longer. If the appliance is intended for fixed-wiring, the manufacturer can (and arguably should) tell you the rating of protective device the appliance is rated for - it's in the product standards now - much to the annoyance of a number of contributors to this Forum.

  • Agreed - if the appliance will not overload the socket-outlet circuit, or unbalance a ring-final circuit.

  • The first question must be - Why?

    A good opportunity to boycott such penny-pinching irresponsible manufacturers who make products unsuitable for the system to which they will be connected.

    Are there examples of European products unsuitable for connection to a 16A circuit without additional protection?

  • The first question must be - Why?

    Because clearly this product is intended to be hard-wired, and, as per my comments by myself and others below, regarding overload of 16 A and 20 A socket-outlet circuits, and unbalance of a ring-final circuit, I really don't see how the manufacturer could identify anything other than 'dedicated circuit' for the general case installation, regardless of the European country (EU or otherwise) this product is to be installed in.

    A good opportunity to boycott such penny-pinching irresponsible manufacturers who make products unsuitable for the system to which they will be connected.

    Very harsh ... sounds to me like this manufacturer is quite likely recommending the correct course of action for many domestic installations.

  • Does your kitchen have a conventional oven/grill?

    If so, put your Zanussi on Gumtree and buy a standard microwave. No chasing required!

  • I don't think that it should ever have been put on a socket circuit. Basically, if it doesn't come with a plug attached, it is not intended to be plugged in. Just remember the six Ps!
