Preparing For Installation
For example:
In US NEC, you may use a 14 AWG wire with a 15 A
n
breaker for up to 12 A continuous current (or 12 AWG for a
20 A breaker for up to 16 A continuous current)
Note that every jurisdiction will have different requirements
n
as will each application, so research the regulations for
your local jurisdiction to determine which wire size and
type is correct based on the maximum AC input current
marked on the chargers and given in AC Input
Specifications on page 55.

Other examples of AC wiring requirements:
Conductors and flexible cords shall be stranded copper for the
marine environment.
The AC (mains) wiring supplying the XPLORE Charger must be
protected by the correct size and type of branch-circuit rated fuse
or breaker to meet the applicable installation codes. If a fuse is
used instead of a breaker, a correctly rated disconnect switch is
required ahead of the fuse so that power can be turned off,
allowing fuse replacement and safe maintenance of other
equipment on the mains circuit.
Additionally, an AC junction box must be installed next to the
XPLORE Charger. See Figure 8 below.
