Installing Wall Lights on Steel Building

[Davey4000]

I just had a 40x60 steel building erected and I'm getting ready for the lighting. I have a question about installing exterior wall lights. How do you install junction boxes in areas where there are no girts for attachment? The building is insulated.

Mount the box on the nearest Z brace, whip out of it directly into the back of the fixture ( I'm assuming your using HID wall pack lights) Be sure the fixture will accept 90 degree wire, if not you may have to install 105 degree wire in flexible conduit.

Yes, wall pack lights. Thanks for the reply. Makes sense to me!

Using the wrong conductors will result in cooked insulation in a wall pack, just a FYI....

HID should have 105C wire whether it calls for it or not. That stuff gets HOT.

I made sure to use 105C flex cord on my MH lights in my shop.

Seen it a many a time, have yet though to see anybody actually use the 105 degree wire their supposed to.
