Can anyone point me to a source of meter tails bigger than 35mm?
I'm
having a three phase 160amp per phase supply to a workshop, need
probably 50mm tails (anyone able to confirm??)

Table 4D1A, 70 deg. PVC singles, Ref. method F (free air or
perforated
tray), 3-phase, cables touching in trefoil formation:

- 35 mm^2 - 137 amps
- 50 mm^2 - 167 amps
- 70 mm^2 - 216 amps.

but no one seems to stock it. Any pointers gratefully received.

Try the more industrial orientated wholesalers like Newey & Eyre or
CSE
(http://cse-distributors.co.uk/cable/index.htm).

Andy thanks for that. Is there a derating factor as its in 100mm
square pvc trunking or does that count as free air?
