Is it acceptable to use the main gas line to use as a main ground?
The house is a 2002 built.
The home has plastic supply lines.
As you can see there was a ground at the main water line.
I personnaly would think you would have a better ground at the water line since it is 6feet instead of 3 feet for the gas.
Also home has no AFCI at the main box. Home was probably built before the 2002 code came out. Would you recommend as an improvement to add to the box?
One more question. What year was the code for the waterproof exterior covers. This one is missing and I would recommend installing.
