Looking for advice on how-to for a motor breaker panel (VFDs).
I want to give a 100-amp fused disconnect 480V3-ph, feeding a small 6-circuit panel for use with VFDs, 20A 3-ph individual VFDs, but much smaller loads.
I have a 480V 3-ph Delta to 208Y/120v 4 wire transformer that is supplying well under the overload protection.
I want to come off the primary (480V-Y) taps of the transformer to feed the disconnect maybe 50 feet away and up one level.
1. Can i do this?
2. Can the transformer lugs accept more than one wire?
3. would it be ok to use stacked taps on the transformer supply side lugs to keep a decent space between connections?
help appreciated.
