and inverter amperage per NEC/CEC guidelines. It is recommended that
the cable has battery acid resistant insulation and is rated for 90 °C
(32 °F) or better.
Be sure to check with any local regulatory agencies for additional
requirements.
Battery cable lugs
Battery cables must have crimped copper compression lugs or crimped
and soldered copper compression lugs. Soldered connections alone are
not acceptable.
High quality battery cables are available from Xantrex in an assortment of
lengths from 1½ to 10 feet in #2/0 AWG and from 1½ to 15 feet in
#4/0 AWG sizes. These cables are color-coded with pressure crimped,
sealed ring terminals.
Overcurrent
protection
For safety and compliance with regulations, battery overcurrent
protection is required. Fuses and disconnects must be sized to protect the
wiring in the system and are required to open before the wire reaches its
maximum current carrying capability.
Xantrex DC175 and
DC250
The NEC/CEC requires both overcurrent protection and a disconnect
switch for residential and commercial electrical systems. These items are
not supplied as part of the inverter. However, Xantrex offers a DC circuit
breaker disconnect module specifically designed for use with Xantrex
