10. For Single Phase Circuits: Set voltmeter to ACV, verify zero
voltage between (3) test point combinations {L1-N, L1-GND,
N-GND}, Switch meter to DCV. Repeat all (3) measurements.
11. STORED ENERGY is present whenever DCV readings are
observed. The energy must be removed or discharged before
the enclosure is to be opened or electrician work is to be
performed.
12. Remove any unsafe load conditions and notify personnel
power is about to be restored. Follow facility and equipment
procedures for restoring power.
13. Repeat step 9 or 10 measurements but now verify proper
operating voltage conditions appear on the Test Point
combinations.
Note: For greater accuracy, multiply voltmeter reading by a factor
of 1.03 to determine actual line voltage.)
