I'm just curious, but has anyone deliberately or accidently touched a live supply and tripped a 30ma RCD, and if so, did they feel a shock before the RCD operated ? Theoretically it should trip within 2/10 of a second at 30ma fault current and usually around 25-40ms so I would expect it...

I find the sheds that ban all sheds would like to ban to be in the most part convenient, useful and helpful, and are becoming increasingly good value. However, I find that ban all sheds is in the most part tedious, boring and unhelpful, and is becoming increasingly irritating. You can...

May sound a daft question, but how do you do it neatly and quickly ? I have found the best method for me is to strip each T&E cable, cut the individual cores to suit its entry point, and terminate one cable and one conductor at a time, lightly tightening the screws, and then adding each...

Any top tips to make the wiring inside the panel neat (been using Accenta G4 compact) ? I have wired a couple and haven't been satisfied with the outcome in terms of tidiness. Main problem caused by having to use chock blocks to wire tamper circuit in series and to connect the multiple...

I have installed Accenta G4 panel with 2 PIRs, one in a portacabin used as an office (zone1), the other (zone 2) in a big wooden shed/workshop which is drafty/may have rat vistors ! Zone 2 alarmed, at 0530 a couple of days after installation. There had been no (human) entry. After reading up...

As the subject line implies, I have a tamper lockout on newly installed alarm, with just two sensors, bell and 1 remote keypad. I have tried to link out the tamper circuits to the bell (TA) , the RKP (TAMP) on the left side of the panel, and the main tamper loop TAMP terminals. What I found...
