WebAs the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Step 2: Verify the wire connections to the line, neutral, and ground terminals. This causes the voltage between neutral and earth to be present. So, for the neutral to ground measurement, you'll want half of the 3%. If there is an amperage reading with the clamps around water pipes and gas pipes it could be from a neutral ground reverse (found one where on a pull chain light with an outlet they had it miswired on the outlet plugin) or the current reading with the amp clamps around the pipes could be coming from a voltage leak, say from buried underground electric, feeding the house or bad underground wiring feeding say a yard light.
