    Running lights across scaffolding

    Hi, I have run some outside lighting for a customer in Hi-tuff cable. He now wants 2 additional lights run across scaffolding which has been put up.

    Resistor across L-N in an adapter box. Possible or asking for trouble?

    If I place say an 80 Ω resistor across L-N, would that generate a load of approx 2.8A. I’m looking to create an artificial load of a socket circuit so I can locate the current at the DB using a clamp meter. Used to use plug in 3kW heaters but not an option anymore, also definitely not able to...

    Have come across a 16A Ring Final

    I've not come across this before. The current regs state it should be on a 32A MCB. I've been asked to re-wire a bedroom which will involve extending this ring. It already serves two other bedrooms and the lounge. I know I probably should tell the client to upgrade this MCB to 32A, but is it...

    What Sort of Consumer unit would you Guys Advise me to use to replace this old unit

    Went to a job today and noticed a length of metal conduit going across a pathway. The metal conduit is not earthed.

    I just wondered what people’s thoughts were as to weather it should be earthed being an extraneous conductive part? It’s fixed to the concrete floor and if there was a break down in insulation there could be a potential difference. If you do bond it could it be introducing a risk? 1598092922...

    UK Fuse link

    Hi folks, Can anyone tell me more about a fuse link (I came across several in a communal cupboard today) . Was not expecting this and immediate thought was Bodget and Scarper had been here. Best described as a brass link similar to a piece of galv pipe inserted in place of a BS88..hence my concern!

    Came across some cable I haven't seen before

    I came across some cable today I haven't seen before. It has some sort of tough, inflexible pvc type sheathing (definitely not rubber). It's quite a light silvery grey and more oval shaped than modern flat T&E. Rubber insulation. No CPC. Probably tinned copper conductors, but maybe even...
