    Hi there, I’m a confused landlord after a bit of advice please... I had my property renovated including electric 6 years ago. The RCD operating time for lights was tested at 16.4ms back then.

    Polarity test failure on SPD extension leads

    Evening all, This has probably been answered somewhere here, but in case it hasn't... I have a Fluke 6500-2 and had trouble testing SPD extension leads as you cannot drop the voltage to 250V using the IEC lead test button. I found a way to set up an auto test sequence to include EB and 250V...

    Immersion heater failure

    I've just rewired my old I.H. and it seemed to be working fine although it was quite noisy. Something tripped the RCD last night and I suspect it was that. Now there is nothing - No noise at all. I don't have the meters to test it unfortunately. Is it likely that it's packed up completely with...

    I was watching one of the SparkNinja videos recently on (I think) earthing and bonding and in the related chat they mentioned doing an inspection on a caravan park and almost half of the 100 or so RCDs had failed. Two years later when they went back for another inspection (and the owner had been...

    Premature failure of appliances

    A parent at the school asked me why they might be going through a lot of appliances. Washing machine less than 4 years. kettle 3 years and LED lamps, less than 6 months. There were other things, but can’t remember lifespan. I popped in on passing one day and did a quick test on the kettle...

    T5 8W tubes - unusual failure rate - is it the tubes?

    The lighting on my boat includes about thirty T5 8W 12" tubes in conventional 12V fittings of good make (mainly Labcraft) with HF inverters, taking one, two or three tubes as required. For over 25 years these have worked more or less flawlessly; the only outright failure was when water got into...

    A Bad 3-Way Switch Can Cause Failure of the Other?

    SPD Failure

    Came across this today. Could this damage & unit failure have been caused by a surge? Normally just see the panels go red but have never seen the burn marks.

    Been using these for lightweight fixtures in plasterboard for about six months now and they seem remarkably reliable for something so simple. https://www.screwfix.com/p/rawlplug-tap-it-plasterboard-fixings-screws-metal-30mm-25-pack/7610p There's no worse feeling than when a pig tail spins out...

Approx 9 inches of the tube leds extinguish for a second then relight but not repeating for long. My question is ,"how common is this in the vast experience...
