I called the electrician back and told him about the situation. He came by to take a look and said that, yes, the outlet was indeed too close to the propane tank according to the NFPA 58 guidelines. He also told me that it would cost $350 to move the outlet (it cost over $500 to install it initially). His refusal to fix his mistake made me angry enough, but then he started trying to explain.
Electricians, he said, follow NFPA 70, the National Electrical Code (NEC). The law only requires licensed electricians to know and the NEC guidelines. He had no idea that installing the outlet so close to my propane tank violated another NFPA code until I brought it to his attention. Furthermore, because it was not a violation of the NEC, he wasn’t going to move it without charging me.
I was able to convince him to replace the outlet with a blank faceplate for free, so at least my propane technician wouldn’t refuse to perform my next delivery. But, that’s beside the point of telling the story. There are two valuable lessons to learn here that can help you stand out no matter what industry you’re in.
