2. Using a Volt-Ohm meter (VOM), check the following test points to make sure they conform to
the specifications for the PDCA and local electrical specifications:

a. Neutral to ground voltage can vary from millivolts to
several volts depending on the distance to the
ground/neutral bond at the transformer. Anything
over 3 V should be investigated by a site prep or
power specialists.
