Cable for three phase lathe

We have 4-core 4mm HOFR (TRS in old money) here if you want to call in, we're in Luton. We've got about a 6metre offcut on the floor (new cable)

What does HOFR stand for, Peter?

I've been able get cut lengths of 3-core + earth (PVC or equivalent) for fixed wiring,only up to 2.5mm I think, from the likes of City Electrical with no trouble.

SWA is really for burial or being clipped against a wall or cable tray. The cable we offered was standard heavy-duty TRS rubber cable, 3 phases plus earth.

For armoured flexibles you can buy Sy-Flex which is a clear PVC sheath over armoured braid then flexible cores inside. We have some 7-core 6mm lengths of that one, and it is only about £4 a metre plus VAT to buy trade.

The braid is not really supposed to be used as an earth core except on the SWA where it has to be used with special glands that capture the armouring and provide continuity of the earthing.

I thought I had responded to the group, but it must have gone to Tim directly.

HOFR is Harmonised Oil resistant Fire Retardent.

Wicks carry 10m 3 core 25amp steel wire armoured cable, you will have to provide another earth, or use the armouring (I didn't say that really!!!)

I use this (4-core) on my Ward grinder & Ward lathe (different Ward companies) as they share a wall socket & I have to unplug one to plug in the other. I was surprised at how reasonable the price was. In fact I've generally been very pleasantly surprised at cable preices recently. I bought a drum of 2.5mm yellow arctic not long ago, when they told me the price I didn't believe it - because it was so low!! Have there been big reductions in recent years?

Farnell in one

For 1.5 mm x 4 core cable, ( 15 amp) per meter part # 385-2957, at £ 1.00 per metre.

several other sizes and core numbers available

BTW I think regulations have changed and even if you use the correct glands with SWA cable you must still have an earth wire as well.
