Most variable speed drive I have seen use a shielded cable, low voltage ac or dc to control a variable speed drive remotely. Is it possible to use THHN and pull it in with line voltage 277 & 110 to control a variable speed drive remotely? Or is this a code problem?

Thanks

If you are asking about the speed control circuit, it is likely an Article 725 Class II circuit and is not permitted in the same raceway or cable with the power conductors.

Looks like I will be running some conduit for that control circuit then.
Thanks Don for the quick reply.
