I fabricate a custom EVSE mounting pedestal. it is made from stock aluminium rectangular tube, with a top cap welded on. it is 2" deep x 8" wide, height is adjustable up to 5 feet above grade with 3' underground in concrete.I installed dozens of these without issue and passed inspection. I run PVC into the bottom of the unit, then just free air THNN inside the pedestal, as the pedestal is sealed on top and bottom and the only penetration is a chase nipple into the back of the EVES unit.last time i installed one the inspector failed me because the pedestal is not a UL approved wire way. I was able to run 3/4" LT through it and use a 90 DEG connector into the back of the EVSE unit. this satisfied the inspector as the THHN was now inside a UL listed raceway. however I am wanting to install one for a 100 amp EVSE. this would require #3 THHN and 1" conduit. a 1" LT 90 DEG fitting is over 2" deep and will not work. Is anyone aware of an conductor that has insulation that will allow it to be installed in a non UL wire way like this? or do i need to get this thing UL listed, probably takes years and thousands of dollars.
