1. PRE-INSTALLATION CHECK

Earth resistance test and recloser nameplate

Ensure that the earth resistance test result is acceptable.

Ensure that switch rating matches the system voltage.

Note: Three-phase reclosers with internal voltage transformers (identified by three nameplates) can only be removed under an electrical access permit; an insulation resistance test between V1 and W1 is not applicable.

2. INSULATION RESISTANCE TEST (FOR A SINGLE-PHASE RECLOSER)

Use a 5kV insulation resistance tester. Measure the resistance after 1 minute of testing. Put the test recloser in the OFF (open contact) position. Operate the manual trip level if required.
