First of all, running #4 from 100 amp panel outside to ground rod about 15 feet away on the side of the house. Slam dunk. No problem. Inspector says good luck, call me when you’re done.
Now for bonding the water system.
-The main panel is in the back of the house, so it’s a pretty long run from the panel to the first 5’ of water pipe entering the house.
-In the future, plan to move the main panel to where the ground rod is, about 15 feet from its current location.
Could the bonding wire to the water pipe be spiced mechanically when this move occurs?
Could I cut this wire, acorn it to the water pipe closest to the current panel location, then run another wire acorned right next on the pipe and out to the new panel, so only buying like 20’ of wire instead of 60’.
Also, since the previous home owner, put a gate valve with PVC right where the water line enters the house, I assume I need to put a “jumper” bonding wire over this short piece anyways, so thus I’m kind of using the copper pipe as a splice mechanism.
Essentially, do I need a continuous load path with one wire for the water bonding, or could I splice with acorns and the pipe itself wherever to reach the desired water pipe in the earth coming to the property and have different pieces of wire along the pipe.
Also, can this wire just be terminated on any screw on the neutral bar or does need it to wrap in with the main ground electrode on the neutral bar’s big screw.
Another thing I thought of was run one “pyhsical” wire from the water pipe to the panel to the ground rod, but it really wouldn’t be able to wrap around the screw on the neutral bar, just the side of the screw since the wire continues back out the panel. Is this OK?
Just trying to save some time and money if I move the panel in the future.
