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.
• 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).
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.
