I am in the final stages of finishing my basement, and yesterday I had what I thought was going to be my final electrical inspection. The inspector waved this wand thing in front of some of the switches and said they were not grounded. These were on two separate circuits. I had connected the bare copper wire to the ground post on the switches, so I am not sure what else to do. One other piece of info is that on one of those circuits (the 20A circuit in the bathroom) there are outlets connected in the same circuit. I checked the outlets with an outlet wiring tester, and they showed that they were properly grounded. Any ideas on what to check? Also, I am not sure, if I do change something, how to check the switches to see if it fixed the problem and that they are grounded. I did not find this "wand" the inspector used at my local hardware store. Is there any easy way to check the grounding of a switch? Thanks, TS

I've installed a sub panel in my detached garage. It is fed from a 60amp breaker in my house service entrance panel. The sub panel ground and neutral busses are not bonded. I drove an 8' X 5/8" copper rod into the ground and attached it to the sub panel ground bus with AWG 6 copper stranded. How can I tell if this single rod provides an adequate ground for the sub panel?
