STEP 3: AC Output Circuit Connections
CAUTION
Do not attempt to make connections to the ACC-1500-500 AC Combiner if not qualified for
electrical work.
See NEC Articles 310 and 690 for proper conductor sizing. The phase lugs are shown in Figure 3-5 and
their specifications in Table 3-2.

Follow these steps when making conductor connections in the AC Combiner:
Verify absence of voltage on all conductors.
Run the AC Output Circuit conductors into the AC Combiner through appropriate conduit and
fittings.
Connect the phase conductors to the lugs and apply torque per the specifications in Table 3-2.
Connect equipment ground conductors to the equipment ground terminals.
