Min size meter tails?

[polo1]

Pig of a day and my brain is mush - is there a minimum diameter for meter tails on a TNS system, assuming they are adequately sized for the max demand?

This is probably a really stupid question........:rolleyes4:

They need to be sized for the rating of the cutout fuse nominally 100A unless you can determine the actual size.

and it's not a stupid question

Thanks truckster - I meant me being stupid rather than the question, and you've nailed it. Why do days like this happen, when even the simplest issue gets the brain cells confused??????? I'll forget the way home if I'm not carefull.
From memory 10mm tails will carry approx 60amps - or have I got that wrong?

 

[truckster]

Clipped direct yes

Thanks again - sanity is slowly returning :blush5:

1.5mm providing everything else is suitably rated

16mm clipped direct for 80A. for anything else it's mastercard, (or calculation)
