and when putting in ground rods for grounding you'll want to see how good they are. you can test them by attaching a multimeter in series between light bulb and power source and ground rod. Have 1 line going to the light bulb and 1 line to 1 leg of the multimeter and the other leg going to the ground rod. Use a 120v 100w light bulb the multimeter should be set to ac volts and read 3 volts or less. |
