Spur for a double socket

    Hi all, sorry another spur question.

    My son has a gas hob and an electric built in oven. Ovens died (very old) and gas hob is old.

    The oven (and cable for the auto lighting thing on the gas hob) cable goes into a round junction box which has one 1.5mm T&E coming out of it.

    Turning off downstairs sockets in the fuse box also turns this off, so must be a spur from somewhere (will need to remove kitchen units to find where it goes.

    The replacement oven comes with a 13 amp plug and says it can be plugged into a normal socket.
    Thinking of changing the gas hob to electric, can also get a hob fitted with a 13amp plug.

    I presume I’m right in thinking 1.5 T&E is too thin to have both of these plugged in. That being the case, if I replace the 1.5 T&E with 2.5 T&E and replace the round junction box with a double socket, is it safe and usable to have both the oven and hob plugged in? Or will I find if the ovens on, two saucepans boiling away and I stick the kettle on, I’ll trip the fuse?

    many thanks

    Firstly, a hob with a 13A plug on it will only deliver 3.5kW of heat maximum. Most hobs are 8kW, cooking will be a slow process. I would suggest a new circuit wired in 10mm T&E from a 32A breaker in the CCU to a cooker control unit local to the hob. Supply the hob, a proper one, with this. Sort out the JB and fit a 13A socket, plug the oven into this. The new circuit for the hob may be notifiable.

    I like your suggestion Bob, but why 10mm?

    Many thanks

    As the gas hob works and he’s getting a new kitchen probably next year, I’ll put on a a socket instead of the junction box and just replace oven for now.

    10.0mm² is a bit of overkill for a gas hob ingnition, don't you think?

    10 mm cable is way oversized for a 32 amp circuit. 4mm is all that is required.

    4mm is too small for a 32A cooker circuit. You really are a mine of bad and wrong information.
