    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. Slightly hesitant running the cable across the scaffolding using the Hi-tuff as I feel it can easily get damaged with the other trades using the...

    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...

    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...
