Connecting the AC to the Panel
See “Connection Types for AC and DC” on page 18 if you are not familiar with
the connections used on the breakers.
When following the procedure, see Table 2 on page 24 for wire lengths and
Table 1 on page 24 for torque values.
See Figure 4 on page 8 for panel electrical connection diagrams.
To connect the AC input:
1. Install a UL/CSA approved strain relief on the AC input cables.
2. Route the AC input cables through the knockouts in the back of the panel.
3. Install breaker(s) for your AC input source. See the documentation for your
breaker to determine how it installs.
4. Connect the AC input ground (bare copper) cable from the AC input source to
the front AC bus on the panel, marked “Equipment Grounding Terminal”.
5. Connect the AC input neutral (white) cable from the AC input source to the
rear AC bus on the panel, marked “AC Neutral Terminal”.
6. Connect the AC line (black cable) to the top breaker (30A panel) or breaker
4+5 (50A panel). See Figure 4 on page 8.
WARNING: Shock hazard
Ensure that the AC disconnect or breaker is open on the AC line before attempting any
installation.
CAUTION
Breakers can be damaged if forced onto the AC “stab-lok” bus bar. Breakers should slide
easily into position without excess force.
Important:
The following breakers are suitable for each circuit:
MAIN: Cutler Hammer/Bryant/Westinghouse Type BR Series and ITE Gould QP Series.
The maximum current rating for the main breaker is not to exceed the rating of the
panelboard.
BRANCH: Cutler Hammer/Bryant/Westinghouse Type BR, BD Series and ITE Gould QP,
QT Series. The maximum current rating for the branch breaker is not to exceed 20A.
WIRE GAUGE: In order to remain within the manufacturer’s specifications for the above
breakers, the gauge of wire used must be selected based on 75°C ratings from your local
electrical code. Wiring with temperature ratings higher than 75°C may be used, however,
the gauge must align with that of 75°C wire.
Important:
Main AC line must go into breaker location 1 (top breaker) for the 30A
panel and into breaker location 4 and 5 for the 50A panel, where breakers 4 and 5 must
employ a ganging mechanism. Bus bars have a protective tab to prevent non-certified
breakers from being installed.
