Hi Guys - its not a TT system, so no 100mA RCD. My guess is that as the (NICEIC) installer was installing new circuits, he wanted to comply with the 17th edition; but obviously he's not thought about the installation as a whole.....

Hi - thanks! UPS already backs up the server, but according to IT technician, the battery backup is very short.... Its a 61008 63A 30mA RCD protecting one of the consumer units that is at fault. My tests concluded that I had 18mA of earth leakage from all the various computers/equipment -...

Hi Dave - The servers are indeed turned on overnight. My initial thought is that perhaps the servers are leaking an earth current which is tripping the RCD, as none of the 60898 MCB's on that board aren't tripping. The wiring and consumer unit are new within the last 2 years, and I've seen the...

Hi guys, I've just started working in a commercial premises as a technical advisor. The building has 2 consumer units - one older MEM board and a newer Proteus board, which has a 61008 RCCB protecting ALL of the circuits on this board My problem is that I've arrived at work this morning, and...

Thanks very much!

Hi I would like to say a big thanks to everyone on this awesome forum who have helped me through the AM2 process. I went prepared thanks to all of your help, and well rehearsed, and managed to pass 1st time. Many thanks to Barge - your AM2 guide was absolute gold dust, a must for anyone about...

Hi mate, I was always taught to isolate the circuit I am working on first before testing for power?? There are 2 parts to your safe isolation, you prove your bay is 'dead' before you install, and then, as you've described, you are given a certain number of scenarios on your completed...

JWS My conduit snapped on the outside of the bend in the machine. I insisted that it was manufacturer fault as have never seen it happen before. The examiner tried telling me that it was because I had it held in a vice whilst cutting it, which I said was rubbish as I always do it that way! I got...

"Good Afternoon, I can confirm you passed the AM2 and your certificate is going out 1st class this week", GET IN!! Thanks so much for all of your help, specifically 'Barge' and 'Andy'. If anyone would like any tips or advice, this is the place to be, I'm happy to help out. Chris

Hi guys, I sat my AM2 on the 20th Oct, and still haven't heard anything regarding my results. I understand that the JIB issue the certificates and marks every Friday in England, which means yesterday will have been the 4th Friday after I sat the AM2. I thought I'd ring the college where I took...

I took the AM2 test last week, not sure how I got on really. You don't have to loop test the SRCD, you only have to use an RCD tester to make sure it trips in a decent time. Remember to set your tester to 30ma, and test half times, 1x and 5x. Please please remember to do the following on your...

Thanks, I might write a letter of complaint; it's not on!

We've got these damn timers on the wall, I had 3 mins left to connect up a couple of cables in my remote stop/start, and 1 terminal was shot. As there's only one assessor who is overseeing testing, you end up wasting 2 mins just to ask him to get a new part, its an absolute joke! Oh well, have...

Hi guys, Just finished my second day on AM2, half a day left tomorrow for inspection and testing. Does anybody else have an issue with the center they sat their AM2 at? I've been wasting so much time on installation through missing screws, dodgy accessories that take 4 times as long to wire as...

Hi Guys, I've been informed that the motor is prewired from the distribution board already and we only need wire the control circuit. Where abouts do you take your live and neutral supply from to power this control circuit on the AM2 test? I'm sitting the AM2 on Monday; my college doesn't have...

Where abouts do you take your live and neutral supply from to power this control circuit on the AM2 test? I'm sitting the AM2 on Monday; my college doesn't have a motor rig like this set up, which may surprise some of you, but certainly doesn't surprise me! I feel fairly confident wiring it up...

Cheers, very helpful. I'm getting some practice in tomorrow at college!! Thanks again

Thanks for this - pure gold dust! Taking mine in 2 weeks...... Just a quick question mate, what do you mean by 'belling' out Pyro cores??! Thanks in advance Chris
