EICR

[leep82]

Ive recently mentioned on another thread of mine that when it comes to completing EICR's my experience is limited. I have my testing and inspection qualifications but have generally only used them to verify new work that i myself have installed, all relatively easy. At the minute I am sub contracting to a local company and tomorrow have to go and carry out an EICR on a pub. I was just hoping for any advice that anybody might be able to give me. Having spoken to some of the guys who already do this sort of work for him i dont feel that i will be anywhere near there speed. This wouldnt normally worry me as i would much rather take my time and be thorough but any advice/tips that could save me time or help me out would be most welcome

just do it

is nothing to worry about. as You told You've made some of new testing before , so when something will look different than You are expect , just check that with a "Book of Magic" (BS7671)

Don't panic, sometimes looking at a DB which isn't properly marked up can over awe you. Just look at it on a circuit by circuit basis.

Do a walk round first, note any observations as you go. Take in where there are switches, sockets, any other equipment.

If you can isolate the DB as a whole and turn on the circuits one at a time then do that. It's much easier to see what's on than what's not.

You know how to test obviously, you know what complies in terms of cable sizes, ocpd and disconnection times.

You'll be grand.

Just a heads up I have found that pup wiring is not the best as generally the landloards will get one of the locals in who once watched somone change a plug and thinks hes a spark, so unless it a nice new pub, I imagine you will be finding a lot of observations , and interesting installation methods

The last Pub I did fault finding in had no labels, 4 fuse boards and the entire install was a mess.

Pubs, restaurants and take-aways get declined when they call...

 

[EMMEC]

right Murdoch , no take-aways !!!! and no pubs ) they always using a cheap "repairers" an on the end You are in the mess

I carry out EICRs in pubs on a regular basis. I find best thing to do is start Cellar and work up, in the kitchens sometimes sockets will be on their own circuits instead of RFCs. Key to speed is Global IRs and keeping mental notes of what is there and not found yet. Wiring and add ons normally to a good standard as the brewery always do the testing and fine the landlords for ---- work.

Didn't understand any of that!

@leep82 are you on hourly rate or per circuit.? As said before pubs are usually a mare, add on after add on! Lim L-L tests and get L-E done! Zs dont R1/R2. Do you use a software for your certs or pen and paper?

 

[leep82]

Once again thanks for the replys. Im on an hourly rate not per circuit. My biggest concern is that i miss somthing. Im not sure how soon my current empmoyer thinks i can get this done, my previous employer who i worked direct to was very particular regarding testing and i like to think im pretty thorough. I dont know how big the pub is, if its occupied etc etc. Probably worrying over nothing. Quick question regarding r1 & r2 tests, been told a few different things by different people. For example just use a wander lead and test r2 or even just calculate it from my Ze/Zs readings

 

[DPG]

r1/r2, R1/R2 ? - careful!

r1 r2 and rn are end to end resistance readings of a RFC R1+R2 would be the combined resistances of a radial or lighting circuit Land cpc and the resistance of a RFC L and cpc once cross connected as per OSG GN3

 

[Richard Burns]

Measuring R1+R2 is a means of calculating the maximum earth fault loop impedance of the circuit.
It also ensures that the earthing is continuous on the circuit.
The alternative to this, if the circuit has already been powered up, as it will have been on an EICR, is to confirm the earth continuity and the earth fault loop impedance by measuring Zs.

 

[FatAlan]

Do you know if there are any previous Certs or reports to assist?

 

[HandySparks]

... or even just calculate it from my Ze/Zs readings

No. For an EICR, where you've already measured Zs, don't attempt to calculate R1+R2, there's no point. (It just implies that you've measured something which you haven't.)
