    Is 0.15M ohms N - E a fault on a cooker?

    Further to my other thread about the connected neutral. I have decided to write (politely) to the rather difficult customer and explain that I was right to indicate that the cooker was potentially dangerous. However, I thought I better check to see if it actually is! I found my results and the...

    Riso fault Power-One Aurora

    I have a small Pv farm 5KW. Some months ago inverter started to measure low Riso<1MΩhm (0.8). I tried to test each string alone and with one the inverter read good Riso and started normally. The other had very low Riso. I tried to check the two pv strings but both have same Voc 340Volts. So I...

    A21 fault on Worcester boiler

    My boiler is still working fine and my new Hive thermostat works manually (just not on the app). The boiler regardless of what’s happening still shows the A21 fault which I believe is an RF signal fault? Any ideas?

    Central heating fault.

    So a customer changed his own stat and wired it wrong and blew 3/4 fuses. Then heating was stuck on so I changed the programmer and this resolved the problem so I think the short circuit had damaged programmer. Now 5 days later the the hot water isn’t heating haven’t been yet. All I can guess...

    UFH actuator fault. Causes?

    What can do this to an actuator? Overvoltage? Wear and tear? Stuck pin on the valve? This is in the German built kit house I’ve done work in before. The actuator controller is powered separately to the central heating boiler.. each room has a stat, which then opens one or more actuators for...

    Maddening MCB Tripping fault

    Hate these. Been called out to troubleshoot a tripping MCB. It's a house I've been to before and I know the wiring is a real dogs diner, but anyway. Got an MCB that's tripping out with no appliances plugged in. The sockets themselves are not in a great state, however continuity and insulation...

I like peace and quiet when fault finding, plus I like to plan it in advance and always first thing in the morning as you know it can get pretty complicated and I...

    my caravan isn’t lighting up tail lights, but all other lights work fine. However… while testing, I got a strange sequence of events. I’ll also point out that the 13 pin socket has the left and right tail lights on different pins, so whatever it is, is affecting both sides. Ok.. with...

    Weird fault that no-one can work out the issue.

    Evening all. Been at a property the last couple of days that had suffered damage due to a surge. I got the power back on all circuits apart from the upstairs lights as it immediately trips. Long story short I broke the circuit down and re-added room by room to narrow down the problem area...

    Dumb questions about PEN fault and solution

    Sorry if these questions are dumb, but I thought I'd ask you guys as I'm brand new to this field. I was watching this video from John Ward and had a few questions about it. 1. In a TN-C-S system, if there was a PEN fault before the service head, the current would go through the protective...
