So I am installing a small belt conveyor that will be driven by a 1/2 HP, 480 vac, 3ph motor. The motor info is:1/2 HP TENV 230/460V, 3Ph, 60Hz, 56C.
I will need to start and stop the conveyor when the adjacent conveyor is started/stopped.
I have a large MCC where I had planned to get the power (480 VAC) from that is very close to where the new conveyor will be. It has a spare bucket with a breaker of unknown size available. Looks like probably 30amp or so. I will have to confirm size.
There should be a photo attached of the electrical schematic I came up with.
The new conveyor motor will be located approx. 40 to 50 feet from MCC.
My questions are these:
Phase conductor wire size = 12ga Correct?
Ground conductor wire size = 14ga Correct?
How do I determine what size transformer is required? 480V primary, 120V secondary I know. Is 50 VA big enough?
Is there a specific type/size motor starter (Contactor) I need? (120 VAC coil) I believe NEMA size 1?
Do I need another disconnect at the conveyor control box since I have the one on the MCC already? I don't believe I do but not 100% sure.
What size fuses do I need or how do I determine the size and type needed?
Should I add overload contacts or is it not necessary?
I've been maintaining/troubleshooting this type of equipment for years but new to designing new control wiring. Any help is greatly appreciated!
