Wire Sizes and Disconnect Requirements
The AC Input/Output Terminal block in the ACCB-L-L1 accept wires sized
#2/0 to 14 AWG.
The ground bar in both models has nine holes and accepts #4 to 14 AWG wires.
The AC Bus Bar (for neutral and hot connections) has dual sizes. The smaller nine
holes accept #6 to 14 AWG wire and the larger two holes accept #1/0 to 14 AWG.
Determine the wire sizes and disconnect sizes required for the installation. See
Table 2-1 for torque values.
The full AC pass-thru capacity is 60 amps. For full pass-thru capability of this
unit, a maximum fuse/breaker of 60 amps is recommended, which corresponds to
a cable size of #6 AWG (THHN) in conduit. If you are using other wire sizes,
please refer to your local electrical code for fuse/breaker requirements.
The following illustration provides the part numbers and placement location for
all field-installable parts. Parts shown in this illustration have been approved by
CSA. Some are available at Xantrex. Others are available at your local electrical
supply distributor. Similar parts purchased from other vendors may be subject to
approval from your local electrical authority.
Important:
Only use copper conductors rated for 75 °C (167 °F). All wiring within the
Long AC Conduit Box enclosure, except low voltage control wiring, shall be rated at least
300 V or a combination of 300 V (e.g., 150 V cable enclosed with 150 V insulation/heat
shrink). Control wiring can be rated for 150 V.

#6 to 2/0 AWG 120 in-lb
CAUTION: Equipment Damage
The inverter’s AC output must never be wired to the utility or generator output. This will
cause severe damage to the inverter which is not covered under warranty.
Important:
These instructions assume that the DC connections have already
been made and that the system ground has already been established. Consult the
Sine Wave Plus Owner’s Manual for additional wiring information.
Important:
Be sure to use wire-ties as needed to keep field and factory-
installed wiring neat and tidy so it does not interfere with airflow through the
Long AC Conduit Box into the Sine Wave Plus Inverter/Charger. This also helps
keep wiring away from potentially hot surfaces.
