Coming behind another contractor that did an HID to LED replacement. Two thirds of the fixtures on the poles are on “normal” power, with the third on generator. Contractor did not pair of the feeds when they removed the fixtures. Now they have crossed up hots between the two different panels, causing backfeeds during power outages. In the old days with ballasts, it was easy to correct at the bottom of the pole using continuity tests, now with LED drivers, that doesn’t work anymore. You have to energize one leg, then find the other with voltage on it. Pain in the butt! Just venting, spent all day in the hot sun, and found four poles so far that have been screwed up, and still have to track down another!
