Just inspected this house and this is the service entrance. It’s not bad, but look at the service conductors. BTW, the client is an electrical code inspector for the county.
At first glance, I thought I was looking at some melting of the conductors. Then realized it was grease. Is there such thing as too much?
Also, this conductor running to the A/C unit, is colored with what looks like a marker - shouldn’t that be done with colored tape? The client agreed with me, and will be making repairs after he closes the house.
