1. Insert key “KU” into Lock # 1 and release key “KB”. This will
electrically lock the breaker at the "CLOSE" position.
2. Insert key “KB” into Lock #4 and rotate key “KD” to release it.
This mechanically locks the 38 kV SEG&TD “Closed”.
3. Insert key ‘KD’ into Lock #5 and rotate it to retract the lock pin
and allow the test port shutters to be opened.
4. Move the test port shutter knob to the right until the test probe
ports open to form a full circle (see Figure 45). While holding
the shutter in this position, install the test probes.

The shutter is spring loaded to return to its closed position so it will
need to be held in the open position for test probe installation. Due to the
spring loading, and the physical size and length of the test probes and cables,
an assistant should be used to help in this process.
5. To install the test probes, uncoil each test probe and cable.
Insert a test probe into a test probe port until completely seated
in the test probe port. Follow the same procedure to install the
other two test probes.

When the test port shutter is fully pushed to the right, the inner shut-
ter will “pinch” into the indent on the side of the test probe locking it in place
(see Figure 47).

6. Move and hold the shutter knob all the way to the right and
rotate key “KD”, extending lock pin and locking the test probes
in place. Check to make sure the probes cannot be removed.
