    Running lights across scaffolding

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...

    AC / DC voltage drops across Diode

    I am unable to find voltage drop of normal silicon diode(0.7v) on Voltmeters during Proteus Simulation. Also we consider 0.7v drop of diode equivalent to DC Source of 0.7v but DC voltmeter is not showing any output and AC Voltmeter shows around 5 volts drop across diode instead of 0.7V.Kindly...

    CT clamp via WiFi across yard

    I want to get a CT clamp signal across a concrete yard. I cannot have an overhead cable, and going underground will be very expensive. Both ends will be in range of a good WiFi signal, both on the same outdoor access point. How can this be done ?

    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!
