    6mm T&E on a 32A Cooker circuit

    Struck me recently as to why we use 6mm T&E for a 32A cooker circuit, when generally 4mm (clipped direct) would be sufficient. Is this a historical thing with BS3036 fuses?

    Quick installation question.

    Hi guys, I would appreciate your opinions please. Would you think that clipping cables direct to an exposed beam directly underneath the floorboards above would be acceptable. All circuits are RCD protected and the customer wants the new cables to match the existing ones which are all clipped...

    9.5kw shower on a 6mm

    Inspections

    Whats the stupidest thing a NIc/ NAPIT etc inspector has ever pointed out to you about an install you may have done? One once told me that all cables should be clipped, even under floorboards. 'OK fine, I'll add 1 k to this 2.2K rewire'.... good grief.
