What size flex 3 metres long for a 2.2kw 3 phase combi woodwork
machine?
What size cable to workshop (about 6 metres) to supply say max at one
time 6kw 3 phase machines?
Would this need to be armoured or just conduited or what?
Separate single phase elsewhere, but could I run a spur from a 3phase
wall socket to a single phase socket (same phase as other single
phase?) or is this against the rules?
I've got some sheathed and armoured 3 core cable. Does this need a
separate earth for 3 phase use, or do you earth the sheathing, or
both, or neither?

thanks

Jacob
