I had a call to a new customer who was experiencing what sounded like nuisance tripping on a kitchen ring.
Some background first.
It's an MK LN insulated [i.e. plastic] split load board, with only one side RCD protected. A direct predecessor [I think ?] and very similar in appearance to the...
BMS installers have attended. After fitting the panel they also replaced the aged lighting in the boiler room with 6ft LED battens as instructed by the lead contractor. This is reasonable maintenance in my books. Ish. They removed old lights, took the lids off the BESA boxes, fitted Klik roses...
hello all, pardon my ignorance in not employing an electrician, however, im a diy'er whos changing the light switches in my house and came across this unusual wiring for my downstairs loo. its a single light which has a fan which can be isolated as necessary. I ordered all the new chrome light...
Hi All,
Main issue is as per title: inverter is stuck in Off-Grid mode. I used Self Use over the summer, which worked well, priority PV order Load > Battery > Grid. Now the UK has moved into pseudo-monsoon season, I'm only generating 1kWh/day, so I shifted my loads to off-peak grid hours...
Hi
Did some small works recently on a farm building, and the origin of the suppky is via the TPN isolator in the video. But it wont budge.
Any advice please?
I am extending the lever all the way out and then pulling down. I did not want to force it in case i broke sonething. It is the feed...
I want to put a new light up, but can't tell which wires go to the switch and which ones I even need for the new light, let alone which ones were originally what color.

I am working on some archway lighting, after a finished install the contractor has changed his mind and wants all of the lights to come on at lux level 35 and half to switch off at 70 lux level via photocell.

Hi Guys,
Is my understanding of why it is bad for a star/delta motor to be stuck in star correct?
1) Star delta starting is used as a method of starting larger motors at a reduced voltage of root 3 , which reduces the large starting current drawn by the motor during start up, therefore...

I've tried all the tips I can find including blue-tac, sticky tape, levering with a stanley knife and a small screwdriver.
Any other tips anyone has please?
Thanks

Can someone show me where im going wrong please?
A 0.25H inductor has a resistance of 35 Ohms and is connected in series with a capacitor of 42uF. they are connected to an AC 230V supply at 50Hz, what is the circuits current? show your working ?
The question is:
If the supply voltage is 100v ac with a period of 20ms, and the supply current (Is) taken by the coil is 6A, calculate the frequency of the supply, overall impedance, Inductive reactance and the inductance of the coil.
I've worked out the frequency to be 50Hz and in order to...
Any suggestions welcome.
The gate company has pulled the draw cord out of the flexi conduit inside the brick pillar and left behind a blockage of tape by the looks of it. The pillar has been back filled so no chance of getting inside.
