NOTE: Typical Source Connections
• Direct to the batteries.
• To battery switches. (Never switch the negative wire.)
• To a bus bar or power distribution panel. Ensure the wire size from the
bus to the batteries is sufficient to handle the peak current of all devices
connected to the bus.
NOTE: Circuit Protection
• ABYC standards require a circuit protection device within 7” (180mm)
of the power source on all wires carrying positive voltage.
• If the circuit breaker is more than 7” (180mm) from the source, a
secondary device (circuit breaker or fuse) must be located within 7”
of the battery to protect the intervening wire.
• Secondary device must be rated based on intervening wire size, and
usually has a higher rating than the circuit breaker.
• Refer to ABYC E-11 – AC and DC Electrical Systems on Boats for
more details.
• A 60A circuit breaker, designed for marine use.
• Red wire that meets ABYC requirements, of the appropriate size for the
intervening wire length between the actuator harness and the battery
(see figure 5-13 and table 5-5).
• Crimp lugs sized for connecting the circuit breaker to the power source.
• Secondary circuit protection devices if required (see note).
