    Domestic Intermittent fluctuating voltage

    We have a problem in my daughter’s new build house (2 years old). She noticed the problem started 2 weeks ago when her lights would flicker at random. The lights can be ceiling lights and table lamps so it’s affecting the lighting circuit and sockets both downstairs and upstairs. I have...

    Intermittent ceiling light

    Hi just after a little bit of advice the ceiling light in our spare room seems to have a mind of its own it rarely comes on if the switch is operated but if left on the light will come on eventually it then works fine for a short period so it will switch on and off but then it decides to stop...

    Fault finding an intermittent RCD trip.

    Hi all, I’ve had a headache of a fault and can’t think what to do next. The house has an RCD main switch, and I’ve verified the circuit which has the fault to be the kitchen ring final. The RCD has tripped once without interference, and several times when a switched fuse spur is turned on...

    Intermittent wiper switch for classic car

    My old classic only has a one-speed wiper. I really would like to fit an intermittent device so that I can vary the time between wipes. I am fed up with reaching for the wiper switch when there is only very light rainfall. Whilst at a steam rally recently, I picked up an old wiper dwell switch...

    Been having an intermittent fault at home now for a few months. All RCBO board, wiring 3 years old. Upstairs socket RCBO trips sometimes, maybe once or twice a week. Always seems to be when we turn something on, for example a light, cooker hood, oven etc. I'm thinking there's a dodgy appliance...

    I had a quick job yesterday where the customer said he lost power to some kitchen sockets, I went round and he had an old wilex board with rewireable fuses. All the sockets in the house were on two 30A fuse wires. Most sockets in the kitchen were in a ring on 1 and the rest of the house must...

    Hi Lads and Ettes! Sure most of you will have had this situation: intermittent tripping and circuit tests fine when you are there. So you try to explain what the householder should do - i.e. next time it trips make a note of anything you have switched on prior to it tripping....turn off the...

    Fluke 115 continuity test

    Hi guys, just a quick question about a Fluke 115 I just bought. When I have it on continuity test, when is it normal to give intermittent beeps rather than a continuous ones? In my case, unless I press down to make a solid connection, the meter gives me a mixture of intermittent and continuous...
