2330 practical exam inclueding testing!!

[blacberry22]

Hi guys I have my 2330 practical exam on tuesday 9th march, I'm happy with my practical side its just my testing side.

Would I be right in saying that I start by checking the continuity of the CPC at each and every point, do we check continuity to make sure that the CPC is connected and that it is electrically sound?

And why do we check polarity on (R1+R2)?

Also why do we test strapers on a installation test?

Thanks guys.

Mick!!!

1: earths checked to make sure its there and working

2: polarity to make sure only line is switched/fused

3: you test insulation on strappers for the same reason as rest of circuit, to make sure there is no breakdown of insulation
