    Jus looking at a new electric oven and the specs say:

    INSTALLATION
    Electrical installation This product requires hardwiring to a 16 Amp fuse and should be installed by a qualified installer, such as one of our Team Knowhow experts.
    Power supply 16 Amp (Requires hardwiring to a dedicated circuit)

    What does this mean? Does it need a dedicated 16A circuit from the CU or is a 16A fused spur from the ring enough?


    I think a spur should be able to carry 26A as that’s 2x13A plugs

    Are they just trying to confuse me so I pay their KnowHow installation?

    Hi,

    Sometimes appliance instructions are just wrong!
    However, in this case we will need the make and model to confirm.

    If this is a single oven and it is rated at 16A, then no, it is not advisable to connect it to an FCU. Only 13A FCU's are available, and you may constantly be blowing fuses (Edit: well probably not, given the sustained current capacity of a 13A fuse - still not a good idea though!).

    You will need a dedicated cooker circuit, and if you were to get one installed, get at least a 32A circuit (for future proofing)!

    If you haven't bought the oven yet, and you only have a plug socket available, then look for a 'plug in oven':
    https://ao.com/l/electric_single_ovens-14596/1-20/42-43-45/
    They will be rated at under 3kW and may even come fitted with a plug!

    If you want some more opinions, you may wish to get this post moved to the 'Electrics UK' forum :)

    Thanks,
    this is the oven I was looking at

    https://www.currys.co.uk/gbuk/house...JNkNb0Guj1xWX46a-1BoCJ0AQAvD_BwE&gclsrc=aw.ds

    I noticed some only mention ‘a 16A fused connection’, but if as you say, they don’t exist/are illegal, it automatically becomes a new circuit from the CU

    Unless there is another way I don’t know


    how do I summon a moderator?

    Moderators, if you’re listening, could you move this to ‘electrics UK’, please?

    If you click 'report' under your message, and just give the reason - simple :)

    Once again, yet another example of manufacturers instructions being wrong.

    They are asking to use something which does not exist.

    Perhaps.
    What circuit(s) have you already got for oven/hob/cooker ?

    I currently only have a gas oven, there is a single socket outlet behind it for the gas hob igniter, which I suspect is a spur (unfused) of the ring

    OP has quoted ‘a 16A fused connection’, this is not the same thing a 16A FCU.
    OP has even made the distinction between the two
    ‘a 16A fused connection’ and (Requires hardwiring to a dedicated circuit) is easily complied with by a 16A fused radial.

    It's a single oven so no chance of diversity calculations.
    But at 3200W, that is so close to 13A!

    Edit: 3.2kW@240V from the manual. 2.94kW by my calcs at 230V ;)

    Although to be clear, i would definitely not connect it to a plug or FCU!

    even closer to 14A and we all know how hot these units run at full power. I'd do my best to avoid the overloaded situation.

    If I run a new radial circuit do I also need a switch in the kitchen to turn the oven off (whether over the countertop or inside a base unit next to the oven) or would the MCB suffice for the sake of isolating the oven without having to physically touch it?
