wanna watch your Zs n all with 4mm....only a 1.5mm CPC in it.....so you have a 32A radial which for MCBs to BS60898 will be 1.16 ohms.....not much especially on longer runs....

All power accessories these days allow a max of 10mm!! Around 5 or 6 years ago it was 12mm!! Makes a hell of a difference when your wiring in 4mm cables!! lol!!

So 4 + 4 + 4 = 10 now! Hmm.

At this point should I also make a rude comment about lighting accessories which won't take 3 x 1.5mm!
Thank goodness the 4mm supp. bonding wire has all but disappeared from the scene! When I did my BS7671 course 10 years ago, I did suggest removing some strands off the 4mm wire to make it fit in the earth terminal as it's only required to be 2.5mm inside the accessory (mechanically protected)! I can't print the lecturer's reply! :90:

Understood the first time!:rolleyes4: Whose clever idea was it to reduce the size?

I'm off to bed! Another busy day tomorrow, full of fun, no doubt! Nite
