Good evening, fellow humans, little tired today. This customer wanted to add a second air conditioner, but his coach was only a 30 amp service. So he decided he would go with a 12 V DC air conditioner. Told him I’ve never installed one put it something I can get done for you. So we’ll rip out the back vent run the wire a harness across the roof. Find that the harness was a little short so I need to extend the harness. Air conditioner comes with pre-wire eight gauge wire. It’s only 15 feet long. I needed another 12 so we used two gauge from the batteries to some remote post behind the wall to extend the harness out and not worry about over amperage seeing how this air conditioner has 100 amp fuse. Once I got this bad boy installed I ran this thing for a good hour and a half while I swapped out a roof air conditioner from a 13.5 Btu to a 15k Btu on the same unit and installed a Max Air vent in bathroom. Needless to say, I think this customer is ready for the nice hot summer coming up. I have also asked to have him keep me in touch on how that air conditioner works cause I have a feeling there will be several people reaching out after this post.
