Table 2. Possible pole connection combinations with the bolt-on
breaker kit.
When installing any of the strap configurations in Table 2
or a three-phase strap configuration, be sure to use
standard phase rotation, as required. For example, when
phase balancing a two-pole breaker, the A strap must be
above the B or C straps on the vertical buses and the B
strap must be above the C strap.
Mounting a Single Breaker
When mounting a single breaker, apply multiple
wrappings of insulation to unused strap contact surfaces,
as shown in Figure 3. A UL-Recognized 105° C
thermoplastic tape (OANZ2) is required. Overlap greater
than one-half of preceding turns, as shown, to achieve a
minimum tape thickness of 0.013 inch.
