    Very strange IR fault - any one seen this before?

    Evening all, Went round to a clients house and did some tests on an outdoor socket. At the junction (in an IP rated wiska box) between the cable coming in from the house and the SWA running to a single outdoor double socket down the garden, the IR test between L-E fails at 0.05 Mohms. When...

    Strange voltage when using dimmer switch

    Wondering if anyone else has had this, getting 24v between live and neutral at pendant when dimmer is off, which means the light isn’t fully going off it’s still sort of glowing. When I replaced this for a regular switch it sorted the issue, just wondering if anyone else has had this and if just...

    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...

    Strange MCB trip

    Hi all, Had my downstairs ring final circuit trip the B32 MCB today. The missus was in the kitchen cooking and had apparently put the kettle on and as it was close to boiling the MCB tripped. I therefore assumed it would be due to the kettle so I checked the 13A fuse in the kettle plug but it...

    Strange circuit breaker activity?

    Hi there. I'm dealing with a difficult to locate problem with our 120V landscape lights. My first thought was there was a short somewhere in the run, but there seems to be something additional going on at the circuit breaker or closer to it. The circuit (one bundle of white, black, green)...

    RCBO passes 30mA but fails 150mA but in a strange way. Any ideas?

    Morning everyone, this is my first post - although i had an account years before that seems to have been lost. Can any of you shed some light onto a situation I've come across. I have a newly installed RCBO which is failing the x5 test with a reaction greater than 40 mS. Now, I don't have a...

    Strange fault

    Installed some new floodlights/pir and switches today. All tested fine, however on power up it was evident I had got something wrong. Upon investigation I had the neutral in the switched live of the PIR. Kicked myself but mistakes happen. Corrected the mistake but still nothing was working as...

    Strange electrical noise

    I've been living in an apartment for a month now and there is a strange multi-toned humming and beeping noise keeping me awake at night. The noise is multi-toned ranging from a low hum to a high beep in very random patterns, randomly coming and going every few minutes or seconds. It ranges in...

    Replacing pool pump: wiring from breaker box through timer to pump acting strange.

    New member, DIY homeowner here. I bought a new in-ground 1HP 120v Harris pool pump (online) and had it installed by my pool maintenance company. A few weeks later it appears blown -- it hums when the power goes on -- but I removed the back and the shaft turns easily so I suspect wiring issues...
