Brilliant chris

Good point re high resistance on croc clips. Seen this with dirty, oxidized connections.

Top tip

I am still surprised with how often I see surface mounted industrial plugs and sockets assembled incorrectly.  As can been seen at 2:16 in this video the 3P + E socket assembly has been installed rotated 180 degrees out of alignment with its enclosure, even though there is a keyway intended to prevent this. This keyway that should be at the back can be clearly seen at the front on the red body of the socket where it meets with the gray enclosure, and as this is not locked in place the socket can be prone to rotating in its enclosure.  

Great vid. Thanks for sharing

Only problem is zeroing the links

How to get these books? (at the end of this video )

Question, I'm curious to wonder why you do the R1+R2 more than once, as your confirming the continuity of the cpc why do it more than once? I am genuinely curious. I agree record the worst result but if you were to use a long lead then you wouldn't need any line conductor at all. It's a conversation I've been having recently and would like your input.

Just do an R2 on three phase....I find it much easier rather than all that shorting out rubbish
