Wiring
Make AC power connections
Use copper wires rated at 167°F (75°C) or 194°F (90°C), depending on the requirements.
Connect the grid (or an equivalent AC power source) conductors to the TB1 terminal, and
the PV conductors to the TB2 terminal.
Refer to Table 1 aPbox Power Wiring below for wiring requirements including wire gauges,
torques and strip lengths.
Table 1: aPbox Power Wiring
Before wiring, check that all circuits to be connected to the aPbox are completely
de-energized, and lock out any associated circuits breakers and disconnect
switches.
• TB1 must be connected to the grid or an equivalent 240 Volt, 60Hz AC
power source.
• TB2 must be connected to the PV system(s). TB2 supports up to two PV
system connections.
• Incorrect wiring of AC power conductors presents a risk of electrical shock
or damage to equipment. Before connecting power, ensure all connections
are made according to the instructions in this document and in accordance
with all local wiring codes and regulations.
• Always connect an RC65 to two wires, one neutral, one ground.
• Protection devices, such as circuit breakers and fuses, should be installed
upstream of the TB1, the amperage of which should be depending on the
site requirements and in accordance with NEC and local codes and
regulations.
• Cut and strip the wires outside the aPbox enclosure and make sure no
copper wires or powder remain in the box.
