STEP 3: AC Output Circuit Connections
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.
