Installing a Single-Phase Meter Flashcards
All Steps 1-11
- Inspect meter
- Don PPE
- Inspect meter socket
- Verify customer main is open if applicable
- Test the tester if a reading of 0 is obtained
- Find the neutral
- Test the meter fitting
- Install meter
- Test meter if possible
- Install meter ring and seal
- Close customer’s main if applicable
- Inspect meter
for cracked glass, loose wiring, and proper voltage rating
- Don PPE
Gloves, face protection, hard hat, vest, boots, clothing
- Inspect meter socket
for damaged clips, loose screws, foreign matter, broken parts
- If applicable, verify
Verify customer main is open
- If reading of 0 volts
Test the tester on a known live source
- Find the neutral
Continuity test
- phase to ground should be no light
-neutral to ground should light
-phase to ground should be no light
- Test meter fitting for proper voltage
Test 1 - source voltage - line side to neutral should be 120V, then line side to line side should read 240V
Test 2 - backfeed - load side terminals to ground source, should read 0 volts
Test 3 - load side - phase to ground fault, test from line to load side, should read 0 volts
** verify continuity of jumper if applicable
Test 4 - load side - phase to phase fault, install jumper from one load side to neutral, then test from line to load side, should read 0 volts. Remove temporary jumper.
