has anyone any experience of this. The boiler is 14 years old and has only just gone wrong. when the boiler engineer looked at it he found there was 240v between the neutral and earth inside the boiler unit.
New to this so be kind.
Run a new circuit in today gone to do R1+R2 on the circuit me at the end of line and the other spark putting the link in at DB. Tester starts bleeping voltage so at first I thought he’d turned the circuit on but he hadn’t. On further investigation I’ve found that from the...
I know the thread title sounds bad but hear me out. I have wired an intermediate switch set up with feed at one switch, switch wire at another and twin and earth as my strappers between to an intermediate switch. My customer wishes to use lightwave switches for the three posistions mentioned...
Hi newbie here. Actually I'm a chartered electronics engineer but am often mystified by the dark magic of domestic wiring!
I have a kitchen counter fed by a live feed which comes up through a quarry tiled floor. I want to move the counter and disconnect that feed. I obviously don't want some...
hi everybody.
My boiler in the caravan keeps coming up with low voltage warning which states that potentially the supply is faulty. I got a plumber out to check boiler and he did a test on the earth to live and got 240v he then tested earth to neutral and got 240v. He said i need to get an...
Hi guys
Just wanted some help in finding out the exact reason in why we test Live Neutral to Earth in lighting circuits.
I understand it in case any loads are still connected and to not damage sensitive equipment but why does it damage it?
Would testing Live- Neutral on 230v still damage it...
Had an email about this screwfix live show this weekend in Farnborough.
Has anybody been and is it worth going?
These things used to be great as you'd get loads of freebies all they seem to offer now is 10% in screwfix which you get if you ask anyway on a big order and a bag of random free bits...
Hi, im having issues with my hive multizone and getting power to my upstairs receiver. I have 2 zones, upstairs and downstairs. I can only get power to my upstairs receiver when my downstairs heating is on. I have installed a loop wire between live and common in my receiver upstairs but...
Just been discussing this story, apparently some metal play equipment was giving people a shock, close to overhead powerlines and a transformer...
a small mention of dry condition, wondering on the cause? could it have been acting as a sort of rod and picking up some sort of fault via earth?
Or...
I am currently redoing a kitchen, (electrics) I tested voltage at lighting cable and form brown>blue-230ac
Brown>earth I got 25ac could anyone shed some light on this please
Damn this heat. I just can't think straight!
Been called to an installation where the ceiling was sparking near a light. All the lights were working ok. The spark was coming from a loose earth wire from the light fitting which was touching a metal ceiling frame. I checked the light switches and...
When I turn my oven on and touch a mains tester screwdriver against the casing it illuminates. It’s only happens when the heating element is on.
The oven heats well and shows no other signs of issues. The casing is clearly not properly live as it’s touched all the time.
Is this something to...
ive got a gaming device that has lots of switches, servos and backlighting in it. It’s powered by 5v for main power, 5v for servos and 12v for backlighting.
It all sits in a metal case.
Just recently I’ve had a strange problem when using it that when I touch certain switches or even if I touch...
Any advice would be greatly appreciated on this.
Visited a job the other day where the light circuit had blown at the board. We Isolated the mains and tested but neutral bar remained live. Found that a rogue twin and earth with its neutral was on the bar and was live however the line conductor...
Attended call out at shop. Freezers, chillers and tills were down. Using MFT on V. measurement got 235V plugged into socket. Tested inside socket at terminals with drummond tester, nothing 0 V. Switched MFT to Loop and the neutral was missing. Just a bit puzzled why the MFT shows V. and Drummond...
