Switch continuity test
To assure proper operation, a continuity test may be
performed on the auxiliary switch.
To test continuity with the switch mounted on the recloser,
check switch contacts with the recloser tripped and in the
closed position. Using an ohmmeter the contacts should
check out in accordance with the following table. Read zero
when contacts are closed and infinity when opened.
Further assurance of proper operation will be necessary
when the switch or switch sections contain both “a” and
“b” contacts. With such an arrangement, a test should be
made for contact overlap in the following manner.
1. With the switch removed, connect an ohmmeter in
series with the “a” and “b” contact.
2. Slowly rotate the switch by hand between open and
closed positions observing the meter.
3. The meter should not read continuity at any point
between the closed and open positions. That is, the
closed contact must break before the open contacts
make.
Switch ratings
Switch contacts are insulated for 600 volts and have a
continuous-current rating of 10 amps. The interrupting rating
of the auxiliary switch contacts is shown in Table 4.
