The odd cr@p I get into. Storm damage some how jacked this roof top heating unit up causing the HOT exhaust to flame downwards and destroy the conduit and wiring. It took 3 trips before we finally got to the bottom of the problem. That is a 480 volt 3 phase circuit in there. Or should I say "was in there". I'm using my phone with the camera reversed so I can see and photograph the bottom side of the conduit to see what the problem is.
