    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

    This has probably been done to death, but... What is the best thing to do if you find 9.5kw shower on a 6mm cable and 40 amp breaker?? I told the customer cabling needs upgrading

    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.

    Hi All, Looking to fit a 10.5kW shower for a builder and he is virtually insistant that we use 16mm T&E as 'That's what he has been told to use in the past'. The installation is in a bungalow so the run will be in the loft where I can clip it direct above the insulation. The run is about 15mtrs...

    Shower Cable...

    Was speaking to someone today who said they were upgrading there shower to a 8.5kw but not changing the cable which is a 6mm. He said it's a run of about ten meteres going through floorboards and up to switch. Surely this must be borderline? personally I would use a 10mm2 but just thought I...
