    Fluorescent fault overcurrent trip?

    4ft old style starter/ballast type fitting which when powered does nothing at all (not a flicker) but trips the 6A/30mA RCBO after maybe 3-5 secs. I didnt have my clamp meter with me when i went to see the fault but assume due to the time delay that its the overcurrent part of the RCBO rather...

    RCBO X5 trip time out, caused by washing machine

    I've used a particular socket in my kitchen to carry out monthly calibration checks (ZS & RCD) on my MFT, for several months with no issues. Last week I carried out my tests on my MFT and the x5 RCD test timed out at 40ms. Thinking I had a faulty RCBO, I replaced today, but the fault remained...

    Over / under voltage trip panel builder required

    Hi, I am looking for suggestions for a panel builder particularly round the Bristol area who could build up an over / under voltage protection unit using a suitable protection relay, contactor and so on and also be able to design the enclosure. Thanks James

    RCBO trip times - no, not the usual what should it be . . .

    I was doing a board change today and 10 out of the 15 RCBO's were returning a value in the region of 19ms at 1x and 30 at 5x. Tried more than 1 MFT (both Metrel but got the same sort of results). So this is still within the 40ms's but with new RCBO's would you personally accept or return them?

    ELI on no trip with Megger MFT

    Does anyone have issues with this test and how accurate is a No trip test? I find my readings seem to change a fair bit testing the same circuit a few times. This is using a 1730.

    Water heater stat without over heat trip

    If doing an EICR and you find an immersion heater stat with no over heat trip do you code it? Another spark I know makes it a code 2 - unsatisfactory. Thoughts please

    Hi I have a 6 way split load board located in the shed and served by 10mm SWA. Anything on the unprotected side of the board tests and works fine. However this is not the same for the protected side. I can plug a radio in and the circuit does not trip, but if I use the lawn mower or a drill the...
