    Domestic Yet another induction hob question

    Hello I have a new AEG induction hob rated at 7.4kw max using power sharing but AEG do not specify a cable size or mcb rating nor will they answer the question I submitted to them by email.

    PME or not PME, that is the question?

    Noticed this near me ... I've got to assume it's a pme rod, but not connected. Maybe an old one that they are going to connect to the forthcoming branch off.

    Domestic PV Generation question

    I listened to an article on the radio about solar panel owners who were receiving payments for electricity generated but were not benefitting from lower electricity bills as a result of their main meters being incorrectly set up on installation in some way. I am wondering if this could be...

    When our Victorian semi was tarted-up in the 1980s, the cooker circuit to the kitchen was ripped out but fortunately since we moved in in 2000 the oven we've been using (with the gas hob) has been OK on a 13A plug. That oven is now well past its best before, and the replacement the wife wants...

    Hi, I would appreciate some views on the following issue I have. The Cooker radial in a house has been wired in 2.5mm T&E, to save the expense of a larger cable. Without boring with the detail, I cannot pull out and replace the existing cable, nor wire in a new 32A circuit using another...

    Working on electrics with 2 supplies.

    I have little knowledge of PV. When working on circuits supplied by a domestic CU, is it fine to just have the main switch off in the CU or should you be isolating the PV as well? The stickers all over the CU's in this example all say to disconnect both supplies.
