EICR question, TT.

[Mr. Anderson]

Hi guys

I'm doing my first PI and it happens to be on a TT system. I've a question regarding the "Detail of Installation Electrode" box...

1, Type... Is that a simple as it sound? Rod, mat etc?
2, Resistance to earth... Is this another space for the Ze measurement or the resistance of the conductor?



and how does the electrician doing the testing find out who is supplying the property in order to find out the nominal voltage and frequency?


Sorry for my apparent stupidity but I'd rather as once now than guess and be getting it wrong for the rest of my career.

Many thanks,
Chris. (newly qualified, as I'm sure you've guessed)

1. Yes, rod, Mat etc...
2 This is for your Rod's Ra value. There is no Ze on a TT system...

Dah, ...The Area DNO that supplies everyone else would be a good guess!! The nominal voltage and frequency will be no different to any other system...

Does your tester not show you the voltage and frequency??

cant understand why people get so caught up on TT systems!!

Me neither don't think much of audis

 

[DurhamSparky]

you just hijacked my post you idiot!! lets fight!

 

[RWJ]

yes you, pointy heed!

lololololol least I'm not a pink -----!!!!!!!!!!!!!!!!!!!

 

[electric will]

I see trouble ahead.
