480v Outlets
480v Outlets
(OP)
Hello,
I am having three 480V outlets installed but due to power limitations only one of these outlets can be used at a time. Can anyone give me any suggestions on how to ensure that we use only one at a time? Thank you!

RE: 480v Outlets
I am away from home and can't look up specific devices but at 120?208 I would consider using twist-lock receptacles and straight blade cord ends on the equipment. Then supply only one adapter cord to go from twist-lock to straight blade.
Another option is to have a breaker panel with three breakers. Mount a slide bar on the front of the panel with notches to fit the breaker handles. Space the notches so that when an breaker is turned on, the handle fits into a notch and the bar prevents any other breaker from being turned on. If approvals are required, consult with a panel builder who has supplied breaker based bypass panels for UPS installations.
