3. If the accessory was not factory wired, connect the
leads to the lugs on the accessory, as shown in
Figure 6. For screw-type terminals, the
recommended wire size is #24–16 AWG (0.4–2.5
mm
2
), with 600-V insulation, and a maximum
diameter of 0.100 in. (2.54 mm). Tighten the
terminals to 11 lb-in (1.2 Nm).
Step 4 – Wire Routing, Cover
Knockouts, and Port Wiring
Determine the wire routing, as shown in Figure 7, as
follows:
• For an FB/FC breaker, use ports B, F, D, and H.
• For an FE/FG breaker, use a sharp knife or wire
cutter to remove the knockouts in the breaker
accessory cover.
Route the accessory wiring out of the breaker through
the exit ports, being careful to dress the wiring from the
accessory without pinching the insulation.
Table 2 lists the maximum number of wires allowed per
port. The maximum number of wires per port is based
on an insulation outside diameter of 0.100 in. (2.54
mm). Scale the given number of wires up or down for
wires with a different diameter.

Step 5 – Attach the Label and
Replace the Breaker Cover
Attach the accessory label to the side of the breaker as
shown in Figure 7.
Replace the breaker cover, as illustrated in Figure 3 ,
Figure 4 and Figure 5. Tighten the mounting screws to
11 lb-in (1.2 Nm).
