Hahahah you know what I do not actually know what that LB is made of! I will be checking tonight for sure!
If you think thats bad you should see the other end where it goes out into the A/C unit, and the tail of 10/2 coming out of it and into a 50A welder receptacle in a non weatherproof enclosure under the deck! ( originally that circuit had a 40 amp breaker on it as well!)
