In the pub last night with a few friends, one of whom has just had a new alarm fitted to his house. He said the fitter switched off his power by flicking the RCD and MCB switches on the consumer unit. He then wired up the alarm, power must have been off about 5 minutes max. Now when he went to switch the RCD back on, he had to flick it a few times before it stayed on and said that sometimes they need to cool down as they can be temperamental. Is this right? Reason I'm asking is I used to have one of those plug in breakers you use with a lawn mower, on it it stated that you should test it each time you use it by pressing the button on it, each time I pressed it, it would take a few flicks before it would stay on, I thought it was dodgy so threw it out lol. So can RCD's be temperamental?
