Installing Truecharge+
2–6
AC Wiring
Be sure that your AC wiring meets the following requirements before you
install the Truecharge+:
• Input wiring
The AC input wiring for Truecharge+ should be three-conductor
cable, providing a line, neutral, and ground conductor in an outer
jacket. The conductors must be No. 14 AWG or larger. For marine
applications the ABYC requires stranded wire. It stands up to
vibration better than solid wire. For RV applications, the NEC allows
solid wire in multi-conductor cable, but stranded wire will again
withstand vibration better.
• 120 VAC, 15 amp branch circuit
The circuit supplying the Truecharge+ must be rated 120 VAC,
single-phase, 15 amps maximum. It may be either a 15 amp
shorepower connection or a dedicated 15 amp branch circuit from
your 30 amp or 50 amp shorepower connection. In either case the
charger must be protected by a 15 amp breaker or fuse maximum.
• Disconnect devices
Each system requires a method of disconnecting the AC and DC
circuits. If the over-current protection device is a circuit breaker, it
will also serve as the disconnect. If a fuse is used, a disconnect switch
is needed ahead of the fuse.
