I'm planning on running some schedule 80 PVC conduit in my garage to add extra outlets. At the same time I want to ground the 2 post rack I have in my garage. A few related questions that appear unique enough because I couldn't find answers online.
- Everything I looked up says I need #6 ground from rack to panel to be "doing it properly". Is #6 really needed? The run is about 15'.
- I was going to just run the ground in the PVC conduit for the outlets and use it as the ground for those outlets and the rack, any issues here?
- Assuming the answer to the first question is yes; since I only need the #6 sized ground for the panel can I step down the ground to #12 or #14 (depending on size of circuit) with pigtails on the outlets? Also, for the last outlet or two past the rack? I know stepping down the hot and neutral lines is prohibited but what about the ground wire?
- And while I'm asking questions, are there any distance from the floor requirements (or good practice) for mounting PVC conduit on the wall.
Thanks in advance!
