Forgot to answer this. When it comes to gas lines, if your gas lines are all (black) metal and electrically continuous, you do not need to bond it separatelyIFyour gas appliances are connected to an EGC (equipment grounding conductor, the "green" wire). I think (I need to go dig a codebook out) that the EGC needs to be sized to any likely circuit that could potentially energize the gas piping (if only your appliance circuits are likely to energize it then the EGC in those circuits, if connected and sized properly, should suffice). If your gas lines have flexible sections (like CSST) then you may need to bond your gas line similar to how you bonded your water line, as they don't want to rely on sections of flexible gas line to be part of a potential fault path. That is something that I haven't done much of if at all though, a lot of it depends on the local AHJs and building codes and I'm not sure how recent the big push for separately bonding gas lines if they have flex is either (I think we ignored it back when I did residential).My water meter is out at the street 30' away but the gas meter is on the side of my house. I have the #4 on the 3/4 inch copper within 5' of entrance. I guess i need to make sure theres a connection to my gas lines too since i read up on bonding etc? I'm considering a new grounding rod too since my old one is like a piece of rebar or some bullshit ofc but it's going into sandstone so maybe that's what made them do that.
What is the application? Is this a simple residential lighting thing where your lights are LED and you just want two 3-way switch boxes? Or is it something different? And it sounds like the two switches need to be 3 position instead of the standard 2 position (on/off) which would complicate thingsSo I need to make two boxes with four leds that have switches in both boxes to control them. Three way switch that turns it off, blink or steady the light. What do I need big p and e
