    Changing IR with voltage

    On a recent EICR i have measured 0.589 MegOhms (@250 volts) on the relatively old lighting circuit (red/black PVC wiring) , i have replaced both outside lights (thinking water ingress as both were damaged). The strange part is at 1000 volts the IR changes over a few seconds to 1.6 Megohms , it...

    Voltage testing

    There has been a wide research on voltage already but my question is which multimeter can give us more accurate reading for voltage calculations, analog or an average digital multimeter like brymen or amprobe?

    Strange voltage and power factor values and installation issues

    Hi, We have installed 2 meters (each meter is a 3 phase meter) for sub-metering in a residential house (1 phase installation per apartment). One of the meters, after correcting installation, works fine now. The other one, in my opinion measures strange voltage values. We had since the begining...

    UK What should the voltage be going into a hardwired ring doorbell transformer in the UK?

    Hello Have a ring doorbell which is powered from the mains using the ring branded transformer that came with the unit. Its been working well for about 2 months since it was installed by an electrician and then just failed last week and appears as though no power is reaching it. I used a...

    Circuit length and voltage drop

    Hi, I'm currently doing my assignment for 2357 and was just making sure I'm calculating the cable length for the lighting circuits right. As depending which way you do it, it alters the voltage drop a bit. On the drawings I've looped in and out at the switches all the way to the final light...

    Voltage readings

    Came across a weird one today… Four single black stranded 12gaTHHN running through 1/2” conduit about 40’ to first outlet box and 70’ to the last, on a branch from main panel. One 20A breaker and one 30A breaker. The homeowner asked to eliminate existing locations and reroute, no problem. I...

    Low voltage over several circuits?

    I extended a bedroom in my basement and had to move a couple outlets from the knocked down wall to the new wall. After, I was sanding down the drywall mud and forgot to completely shut the door of the main panel (which is in the corner of the room). Soon after, I went upstairs and noticed the...

    What voltage to use

    My first question, so be nice. I'm very sensitive. We use 230 volts as the go to figure when doing calculations on single phase. However on page 362 of the regs, they squeeze in another voltage to use on the bottom of the page. Namely 218.5 volts (95%). It's when calculating Zs. I can't...

    Testing voltage between ignition and solenoid

    I'm trying to test if there's voltage between my ignition and the solenoid. The starter won't crank or click so figured I'd start here but am not sure if I'm doing this correctly. I have a male/female connector from the ignition to the solenoid. I disconnected this, connected a probe to the...

    Connecting a low voltage transformer using a external switch?

    Currently I have 4 small low voltage transformers connected to 4 circuits of low voltage yard lights. They are under my deck, and I turn then on and off using switches above the deck. I want to consolidate those transformers into one transformer...

    Odd voltage on Off peak circuit

    While sorting out some issues with immersions at a flat yesterday, I ran into something that seemed peculiar (to me at least). Immersions need new thermostats/cut out, all quite normal.. However, while testing the lower (off peak) immersion I was getting 13V L-N - which I assumed was just my...

    UK Over voltage?

    Good afternoon, a colleague of mine has recently had three brand new Bosch washing machines pack up, each within four weeks of being installed. I did a check on the voltage and it's 246.3v. Surely this shouldn't have had an effect on the machines...? Bosch seem quite happy to keep replacing them...

    Voltage converter help (AU) to (US)

    Hi there, I recently bought a Worksharp mk2 knife sharpener. Got it shipped from the US so I need an adapter for it here in Aus. The sharpener is meant for 115v 60hz power supplies only. In Australia the voltage rating of most households is 230v 50hz I believe? I think I need some sort of step...

    The weirdest problem you have ever heard: slight input voltage increase seems to affect my pc performance drastically

    So for the longest time I had issues in this location while gaming. I am on a second pc build that exhibits the same weirdness that made me actually quit playing Fifa though I loved the game. To use a simple clear example of weird behaviour, a game like Rocket League (maybe some have heard of...
