I had a customer request to install a 3 phase outlet for an outdoor refridgerated truck. The truck runs on diesel but also a corded power outlet for AC back up power. I never verified if the truck was able to accept AC power because I assumed that would have already been done. I was just given project to get outlet and cord to area for connection. Well low and behold the truck wasnt capable of AC power connection the outlet was on truck but didnt go to anything. I wasnt told to verify if the refridgerated truck could accept the power I was told to provide the AC power. I feel as if they are trying to put this on me for not checking. I dont know anything about A/c and especiallt A/c on traillor trucks. I just provided what customer asked. The truck did provide a amperage and voltage to provide to truck but the A/c didnt go anywhere once attached to truck. maybe it was my fault but I kinda feel like it wasnt.....feeling defeated right now! Just needed a place to vent.
