R1+R2 your thoughts please

[leep82]

Hi all, First time poster here so go easy,

Firstly, i am currently working on a hospital refurb for my company. The job is nearing the end and is currently at the testing stage. Having passed my 2391 over 12 months ago and not having much site experience i put myself forward to test the job. I felt confident in what i was doing and as its my name going on the cert i was being as thorough as possible. This got me into a disscussion with a colleague who had tested the ward opposite. When doing my R1+R2 test i was told to do it at every point on the circuit, and so proceeded to do so at all switches aswell as lighting points, to which my colleague replied " i didnt bother ". I argued to him that what if the c.p.c's had been twisted together at the switch and come free from the terminal? I would still get a reading at my lighting point and proceed to think that everything was ok, when in effect i could have an exposed conductive part that is not bonded. I was just wondering what peoples thouhgts are on this.

Secondly and again whilst carrying out a R1+R2 test at a switch which had two supplys present i noticed only one c.p.c. My test results were fine as i wasnt removing my c.p.c at the MET, instead linking the MET and each individual MCB. This though got me thinking that surely it would be better to have two seperate c.p.c's at the switch one from each circuit. If not only for testing purposes but for any future additions or alterations. I did not install the job myself so dont know if this was done delibrately or sombody has just made a mistake when wiring. Again just wondering what your thoughts are on this.

Thanks

You certainly earned the whiskey then! Joystripper or Tommy Bar? I try and show students both, and also making off with just standard tools, cutters and pliers. Bit of a pig but never know when you might come across an M.I. that needs re-terminating !!

Joy stripper when we could t bar or sometimes just side cutters lol unconventional I know but works quite well. We as a relatively small firm used to do quite well the first steel conduit bender I ever used was a bit of wood with a hole in it. Having said that our company went on to re do all the lighthouses all around Scotland. Quite surprising as we are based in the Orkney islands.
But now I am self employed so miss out on working on the bigger contracts.

Last pyro job was about two years ago subbing for Sunderland council. The gaffer was great, he used to give me a drawing and tell me to go there and make it like that. Never any pressure to get it done, he didn't want quick he wanted right so he left me alone. As a result I had loads of time to get it done and it looked awesome when I was done. I've got some photos somewhere, I'll scan them and post in show me your installs (By I'll scan them I meant I'll get one of the kids to do it)

Says the one who PMs members asking if RCD test results are acceptable on a shower install.
Hmmmmm, working in a special location without a copy of the regs or onsite guide. So I assume you're not CPS registered either.
