Here's a classic I found a couple of years ago, there's 1 big balls up in particular.

Is it the Line supply to the top RCD comes off the supply side of the isolator?

managed to finish around 6.30pm. not 100% happy with a couple of the cables in the CU. going to re-dress monday, but had to extend some and couldn't leave without power for obvious reasons. also lost an hour going out for an RCBO and fixing a couple of faults, so was a bit pushed for time. guy wants me to do a bit of outside lighting for him, so will do at same time.

neutrals?

what about the neutrals?

 

[truckster]

Bottom switch fed from top of top switch but bottom neutral fed from top neutral bar so bottom circuits would appear dead when top switch opened but still be live?

Is that blue neutral on the left hand of the board going straight to the neutral bar the supply neutral in, if so it's bypassed the main switch.

 

[telectrix]

what about the neutrals?

pics not very clear on my laptop. was thinking on bottom board that both the unprotected and RCD side neutrals all in common N bar, still linked together.

Bingo.

I've shown this on many a 2391 course, no-one ever spots it.

Going back to Telectrix's original picture..

Can some kind soul tell me where you can purchase that same type of Henley block, and also where you can purchase meter tails that have brown and blue coloured outer insulation, as opposed to the standard grey.

All the Henley blocks that I've seen on sale are brown, and I've never seen coloured meter tails on sale anywhere.

Cheers

JBL, I think they are Lucy connection blocks.
