This came from a commercial contractor's overflow — bought for a pole-barn build that didn't come together, sat in the shop unused. Never installed, never energized. Selling to free up shelf space.
✅ What I Can Tell You:
Original contractor purchase, never used on the project
No prior energization history, no prior service loads
No reason to believe it doesn't work — but I have not personally tested it, and I'm not going to claim otherwise
Missing the original enclosure key
