AC Cabling
source and the inverter•charger and all cabling between the inverter•charger
and the AC panels, circuit breakers, and loads. The type and size of the wiring
varies with the installation and load. For marine and some RV applications,
flexible multiple-strand wire is required. For residential installations, solid
Romex™ cable is often used. Installation codes may specify solid or stranded,
overall size of the conductors, and type and temperature rating of the
insulation around the wire.
AC wiring must be sized to match the current rating of the AC breakers you
provide on the input and output AC circuits in accordance with the electrical
codes or regulations applicable to your installation.
U.S. National Electrical Code and the Canadian Electrical Code, assuming 2-
conductor-plus-ground cable. Other codes and regulations may be applicable
to your installation.

AC Output Neutral Bonding
inverter•charger's AC output circuit is automatically connected to the safety
ground during inverter operation. When AC utility power is present and the
inverter•charger is in Charger mode, this connection is not present, so that the
utility neutral is only connected to ground at your source panel. This conforms
to National Electrical Code requirements that separately derived AC sources
(such as inverters and generators) have their neutral conductors tied to ground
in the same way that the neutral conductor from the utility is tied to ground at
the AC source panel.
DC Cabling
the DC disconnect and over-current protection device, and the
inverter•charger. All installations require multi-strand insulated cables as well
as disconnect and over-current devices. DC cable sizes are indicated by AWG
notation or MCM notation. Under the AWG standard, a larger gauge number
indicates a smaller wire diameter. Under the MCM standard, a larger number
indicates a larger cable. Wire size is usually marked on the cables for sizes this
large.
