I did a call on a 7-400 watt 277v metal arc HID lights that went out. Turns out one smoked and was pulling 50amps for 30 seconds or so before tripping. I find wire nuts laying in loose in boxes and the one that smoked. I take it out of the circuit and the lights work for an hour or so and then my partner is like "you smell something?" Sure, another one bit the dust, so I'm going back with a bunch of transformers and stuff, but I want to fuse the fixtures. They have a 1.7 amp rating, but they pull more than that on startup, right? Is the fuse selection like that of a motor? Size for inrush with a duel element fuse? They are all warehouse lights I got to do of a lift.3WYSAUFE1T
