Was looking at pictures of an install in another state where the homeowner paid thousands for a couple sub panels to be installed. The guy doing the work apparently holds a master license, and I have no idea how he got one! Here is a basic punch list, but not all of it.
1. NM run underground in conduit
2. 60A breaker on main feeds first sub, then double tapped on main lug with 10-2NM to feed second panel.
3. First sub bonding screw removed, but ground and neutral plugged into neutral bar no ground bar. (bonded)
4. the 10-2 feeding second panel is 240V only, yet tapped sub2 with 12-2 and breaker for 120V, using ground as neutral.
5. Sub 2 is bonded. Again, no ground bar.
6. no ground rods
7. List continues to smaller things like wire stripped too far back, wire not marked correctly, etc.
The most unsafe thing here is that 10-2 is protected only with a 60A breaker. I am honestly just wondering how this guy has a license?????
