4mm/2.5mm T&E

[R-fur]

What about buying from Ireland, I believe they now have full size insulated earths in their T&E.

Anywhere really, the standard in Oz is for 2.5-6mm2 twin and earth to have a 2.5mm2 earth conductor. Probably related to the fact that we use C-curve MCBs as our standard breakers, quite uncommon to see a B32 here.

Ah, interesting, the things you learn. Had no idea C curve was standard there!

I'm not sure I'd even go to those lengths really, though my understanding is that 4mm is basically unheard of over there anyway.

so their rulers go 1mm, 2mm, 3mm, 5mm, 6mm?

must be tricky to measure anything.



Sorry.

Agree with the 4mm radial argument but what happens a year down the line when they want an additional spur from a socket...3 x 4mm cables in a socket, a bit tight or not?

Not sure about other brands, but all the normal MK sockets I've seen are rated for 3x4mm (search for "terminal capacity" in this doc: https://www.mkelectric.com/Document...Dimensions tech pages for catalogue FINAL.pdf)

In any case, that's actually an advantage in my book - you can branch from a radial all day long without too much consideration, whereas the number of times I've seen cowboy style ring spurs (6 double sockets hanging off a single unfused spur, plus sometimes broken the ring in the process) makes me uneasy.

It sounds like it is going to be easier just to put in two 2.5mm / 20A radials.

Whether you join the ends and go with one 32A MCB would be ecumenical matter...

Better check with the vicar...

Why not just run a 2.5mm single from the furthest point on the radial back to CU.

edit double insulated obviously.

Ah! Ted! I see what you did, there.
