    Disconnection Time Requirements?

    Why do circuits 32 amps and under require a 0.4 second disconnection time at 230 volts, but circuits over 32 amps are legally allowed 5 seconds? 115 volts for 5 seconds is enough to cause injury to the human body.

    Another outdoor power thread... seems the time for it!

    As usual – I preface this with the fact that I will be engaging the work of an electrician to do this.. however, I like to get my head around the works beforehand. This will NOT be a DIY job – I’m nowhere near skilled enough to contemplate such a thing… but with that caveat in mind – humour me...

    Max Tripping Time

    Would anyone know the max tripping time for this earth leakage device? I’m guessing 500ms it’s time delayed but I know that figure is for RCDs and RCBOs, I tested it at 560ms Thanks

    UK Help with a tampered eco 7 time switch

    So, we moved in a month ago and only just noticed on our first bill that the meter has been stuck on "Low" throughout the whole day. Great! Except our storage heaters have been running 24/7 because they're wired into the off peak circuit, meaning we spent just under £100 in a month :0 Our...

    Can I use this Time Delay Switch on a panel heater?

    Just a quick one! I believe this time delay switch should work for my old panel heater (1.25kwh) because it handles loads up to 16A. Can anyone confirm this for me? I had someone tell me I needed a fused spur switch but others tell me I don't. FYI: the aim is to ensure the panel heater turns...

    Hello, I have a 12VDC battery bus where I charge with solar PV and a wind turbine. The system is controlled using a Siemens PLC.

    Time delayed rcd’s and fault protection

    Have been to a farm today that has a 100mA time delayed RCD main switch covering a DB that has MCB’s on majority of circuits ( less than 32A) and 30mA RCBO’s on sockets, lighting etc. What I was thinking was does this comply with regs as circuits less than 32A should disconnect in less than...
