Table 2. Possible pole connection combinations with available strap
kits.
When installing the strap configurations in Table 2, be sure to
use standard phase rotation, as required. For example, when
connecting the first option in Table 2, connect pole A, followed
by pole B moving down the vertical bus. When installing a two-
pole and a three-pole breaker in the double-branch assembly,
arrange the straps in the typical three-pole configuration as
indicated in Figure 1. The AMCB4EB strap kit contains an
alternate circuit breaker mounting bracket for installing type
TEB or TED breakers in a four-pole, 2X (2
X 1.38 inches),
double-branch assembly. Secure both breakers in each branch
to the center hole in each mounting bracket and connect two of
the three strap assemblies as desired, as in Table 2.
Apply multiple wrappings of insulation to unused strap contact
surfaces, as shown in Figure 2. 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.
