I ma going to install a 30a 240v A/C circut to the outside disconnect for the A/C unit. The bkr panel is located on one side of the home and the A/C unit is directly across the trailer so I decided to run down out of the box to under the trailer and across to the other side. Tha trailer has skirting around it so I wanted to know if it has to be piped all the way under the trailer. The NEC 550.15(h) says "Exposed to weather" does the skirting make it not exposed to weather?
