Eicr

[Platinum lad]

Hi all need some advice when filling out test results on eicr's after carrying out live zs tests do you leave out R1 R2 column as in a lot of cases the measured reading is below ze value do you just make a note that it is a measurement and not a calculation?
any help appreciated

 

[Jay Sparks]

Right, im treading very carefully here...lol.

But there is a certain scenario where a tick is applicable in either the R1+R2 or R2 column instead of actual readings. Not that i've ever done it.

Thats on a minor works cert. Its says "tick" or "Ohms".

Dear Sirs and Madams,
First post,as a second year apprentice working with a very meticulous,neat and willing to teach older electrician,i have been shown on eicr and tests to always do the full crossover tests on ring final circuits.To verify continuity,polarity and non inter connection of the ring final circuit,not just end to end readings.Many thanks for all the good information on the site.

Have a read and understand guidance note 3
It will help you to get a "better" understanding of what is expected of the procedure required than you have at present

Will do,thanks

....or the cpc hasn't been terminated in a terminal which is pretty common especially on pre 17th edition as no testing was necessary and the cpc was just an earth and treated as unimportant in a switch. And the cover needs to come off the ceiling rose as a BC doesn't give an earth and nore does an ES usually, more than one light fitting per switch and you don't know if that has continuity without removing the cover.

My point was it just depends on what quality of work you do and IF you take signing your name to the report seriously or not.
If it's an EICR or periodic then you have NO idea what the guy was like who installed it or who has done what since.

Me I'm just a Part P'er so wouldn't presume to tell a proper sparks what to do but the guy who took my Part P course was great, (it was one of the first ones), one of the best courses I've ever been on and it reinforced a lot of things I'd done over the years and I found the reasons behind some things I'd read but not fully understood.
One thing I do have is respect for that thing we deal with as our job, it just loves to get out of that wire and get to earth, our job to make sure it doesn't but if/when it does then it gets there damn quick and blows the fuse!

but it gives you an R1 though...doesn`t it...

 

[thewetspark]

.....Yes it could give R1 but from where, maybe not the rose as that may be the fly from a jb, etc, etc. If it's not your work then aren't you supposed to ensure continuity of CPC to EVERY termination so can't assume the guy did it right?

You are correct mark, on a periodic (EICR) a tick in the R1 or R1+R2 box is acceptable, not good practice, but is acceptable. I have never done it, and i dont teach it either, if you are going to measure it, then it is just as easy to enter the result instead of a tick, and dead testing is more likely to show up a fault than live testing.

you use the R1..at the drop..(furthest point) ...then using a wander lead get your R2 of the 3.5mm screw on the switch front...therefore negating the need to remove the front (think easily damaged decorations)....you would of course have confirmed beforehand on your inspections whether or not there was a CPC present as on some older installs (as you quite rightly point out) this isn`t always the case....
but as you stated before that all switchfronts have to be removed to get an
(R1 R2)...so this (as i have quite rightly pointed out) isn`t the case either....
it depends..from install to install....but your inspections/sampling should have verified this...

have to disagree , respectfully , with Howard here.
having just looked closely at the iet generic eicr form , a value is required to be recorded , a tick will not suffice.
unless the circuit is so short you can touch the ends simultaineously then you need to perform the measurement anyway making the whole arguement not to do it a mute point.
