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...
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...

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...
Hi I am reconfiguring a hot wash unit and need to use a flow switch as in attached files.
It controls a light powered relay and timer module I can use a separate relay to control the the others, does this count as a inductive load?
We are talking 25v ac the switch is a reed switch rated at 3A...
Just wondering what your thoughts are about this before I renew the facias/soffits/guttering.
Any help would be appreciated as it's my sons new house.

I need to find a decent quality ('set and forget') rf switch that can be triggered by a contactor or heating relay, distance is only about 10-15m from one outside pump house to another, standard London brick jobby. I've lost track a bit of what's out on the market these days - any suggestions...
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?

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!
Replaced 5ft strip light never seen one before tube with BC caps on, age off property it came out of was 200 years old, Google d smart an brown dated 1961,
Hello guys.
Im a plumbing and heating guy. I work with low voltage all the time and get calls from property managers everyday.
I looked at a range tonight. They've blown two boards and were told by the appliance sales company that they had an issue at the plug so I went and had a look...
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...
