This is my first post and I hope I explain it correctly/ Simply. 1100sq foot single family home, 100 amp service. I am having an electrician replace the front part of my service entrance from the weather head to the meter socket. The main panel was updated about 10 years ago and is not in need of replacement.
The grounding paths are currently this:
-Green screw correctly bonding neutral bar to the box.
-#6 bare running continuously (no splices) outside to 2 rods about 7 feet apart.
-#6 bare that runs to the water pipe right as it enters through the basement wall.
-#6 bare short jumper across the water meter.
The electrician estimating the job said that the #6 from the box to the water pipe needs to be replaced because it now has to be a continuous wire through a clamp at the water pipe entrance and then across the meter. He said “a lot changed in the nec2020. Is he correct or does the jumper wire still satisfy? I hate to think he's adding unnecessary work but I don't want to question him unless I can cite my case.
