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:
Table 3-1 4- and 5-Wire Voltage Ranges
4-Wire 5-Wire
L2 to L3: 200-240 V L1 to N: 200-240 V
L2 to L1: 200-240 V L2 to N: 200-240 V
L1 to L3: 200-240 V L3 to N: 200-240 V
N to Ground:
a
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.
