Hi,
Being a firefighter I have got a pager which vibrates. I’d like to turn on a light automatically through a vibration sensor when it detects vibration (the pager vibrates when alarmed). The light should turn off after some time and it should be also possible to use the light normally (switch...
Morning all,
having a bit of a fun time with my tester at the moment. Bear with me as I'm still in training.
Ive got a Dilog 9083p. I know it's not regarded as the best tester out there but like I said, I'm just starting out.
The problem I have is this. Ive tested Ze at the board and all...
When testing Ze on a TT the only connection between the line and the earth rod is the actual ground.
When you do a Ze is it actually sending a small current through the actual ground from the earth rod at the house to the earth rod at the transformer?
Also, related to the above, I have 2...
Hi all
I've got an opportunity that has come up regarding contracting electrical works through Thames Water, this will be working on their private pumping stations replacing control panels etc and providing reactive call outs for power and pump failures etc.
I used to work on these jobs...
Hi all,
After boosting the hot water for probably too long on our pulsacoil thermal storage, the circuit breaker was tripped and I saw that the timer unit had melted through.
I got a replacement unit and have installed it and flicked the circuit breaker switch back on. The water seems to be...
Hi guys and girls,
So im fitting a new ring final circuit (I did advise a radial) in a newly built extension. the least disruptive way of feeding the cables to the extension is up into the ceiling void and along through the 1st floor bathroom floor (The client has had the common sense to not...

Anyone know the best course of action short of channelling the wall out and rewiring the whole thing?
Kind regards

Hi! Just thought I'd register as I've been lurking around in the background for a while, and found lots of helpful & interesting bits and pieces on this forum over the years. Software engineer by profession, full amateur radio license holder, and often play around in circuit design /...
When starting out subbying, a few people suggested to me that I should start out as ltd. As I would already be paying agencies/umbrellas £20 a week to receive my wages (£1040~ a year) it would work out cheaper to go Ltd and pay an accountant. Subsequently I had a meeting with an accountant and...
Had a tricky job this afternoon. 5 metre run of 20mm flexible conduit running through stud wall then 90' bend. Really struggled getting any of my mighty rods through (splintered 2 of them)
What's the best method? Is there a specific attachment for rods?
Hi All
I have tried to wire in a doorbell and I'm having trouble getting the wire through the hole on the inside to the outside and vice versa. I know the hole is at an angle and no matter how much wire I feed through it doesn't seem to come out the other end. I made the error of pulling out...
I have just fitted a new consumer unit into a house which previously just had a fuse box BS3036 with no RCD protection.
Whilst doing the testing the Zs readings were not as expected. They are around 1Ω throughout the house but at one socket they are 3.7Ω. The customer states this was the socket...
As some of you guys and gals might know, I have been self employed for a couple of years now. I send my books to my accountant who files it with HMRC.
I've been approached by a company who will be working on a local hotel in the near future and I was wondering if it was going to be worth my...
Hi everyone,
Watched a programme recently on TV, a young man was on top of a train (not advised) and the power lines above him carried 10,000 volts. He got too close and it jumped through the air and got him. Thankfully he lived and made a decent recovery.
My question being, is it even...
I am running some flexible conduit within a 5mm steel box profile dwarf wall to feed socket outlets In a small conservatory. One of the sections is 2 box sections bolted together. The flexible conduit will run through this but I'm not happy with the conduit just pushed through. I was thinking of...
Hi,
I am removing my room thermostats as i'm going "smart heating" and need to trace the wire from the room stat downstairs back to the heating control in a cupboard upstairs so it can be removed from the circuit.
I'm thinking all i need is a simple tone generator / wire tracer like the ones...
Stupidly, I drilled through an FP cable, close to a Call Point. It’s plastered into the wall.
Now, Can I chase and reveal the cable, crimp the conductors, use heatshrink and plaster back in?
It would be a hell of a lot easier than any other method but I want to do it correctly.
Cheers in...
