EiCR sampling size

Former Community Member over 5 years ago

Hi all I'm just trying to get my head round this, I hold a copy of guidance note 3 already.

Let's say we have a domestic CU with 8 circuits and we inspect/test only 4 of these does this equate to a sample size of 50% and if we ended up testing all 8 would this equate to a 100% sample.

The bit that's bothering me is sampling to me means that we look at the wiring accessories/connected equipment for safe continued use including signs of over heating, arcing, smell, touch, suitability for location etc in addition to the physical tests deemed necessary with your test meter.

So even if we tested all 8 circuits and carried out a 25% sample size this would equate to 2 circuits being sampled ,is this correct?

That sounds to me like a 100% sample for testing, but a 25% sample for inspection.

Thank you Andy, put like that it makes total sense, it was the wording within guidance note 3 that was causing the concern. I would be happier if a few people could concur though, but it does stand to reason when put like how Andy described it ?
