Where did the 240mm2 SWA calcs come from? that's a big old cable. Ignore please I got my sums wrongCannot get them in Pete, ATEX. Have 2 M75 holes so cannot mod the box.
Yes without eyes on, it was a daft question,Amtech.
FLC is around 420 IIRC. 30+ run on a ladder in a hot factory.
Not sure a motor that size would be started DOLAm I right in thinking with VFDs that it would be a three core cable, with the motor connected in star formation?
Edit:- I'm thinking it may be dependent on the driver itself.

ThanksYes, a VFD cable should be symmetrically arranged, no 4th core.
1 cable, 3 cores to this motor.

Sorry Mate never had any dealings with ATEX why the restrictions on mods?Angled lugs! Never seen them, I'll have a google and give the info to the sub-contractor.
Pete, its a ATEX motor. No mods whatsoever unfortunately.
Thanks Lee you learn something new every day, I understand the restrictions now, thanks again for the reply.Certified kit pal, it has to be how it was designed to function in hazardous areas.
To be fair this is outside the zone now, but if that changes back I don't my name on a bodged up 10 plus grand motor.
