So my buddy calls me over to his house. He abandoned his AC unit and wants to use the 220VAC 50A setup to run power to a Tesla charger. He ran the #6 wire in conduit for the 14-50 NEMA receptacle in the garage. BUT, when he got to the disconnect he could not figure what to do. The picture shows his problem ... The 14-50 receptacle needs two power legs plus a neutral and a ground. The service into his disconnect has two power legs and a neutral but no ground. I'm not sure what to tell him. What is the answer?
