The following illustration shows a Principle of Operation.
Determining the Correct Measuring Point
The preferred point of measurement (if internal bonding allows) is on the conductor
between the ground bus and the service neutral. If internal bonding does not allow access
to this point, an alternate point is on the service side of the neutral line prior to the neutral
to ground bond. In either case, it is necessary to ensure there are no neutral-to-ground
bonds downstream of the measurement point.
