2. Electrical wiring installation
2.1 Electric cable selection
To achieve the best performance and to safeguard your electrical
system it is essential that any electrical windlass be fi tted with
suffi ciently large diameter cable to cope with the current draw
imposed upon it and to keep the voltage drop within acceptable
limits. In any circumstance voltage drop due entirely to cable
resistance should not exceed 10%.
The following table gives recommended cable sizes. The
recommendations are based on total length of cable required,
from the battery, following the route of the cables.
• Total length of cable run is from the batter y to the
windlass, and from the windlass back to the batter y.
DO NOT confuse cable Length with the length of the vessel!

• In Multi Station installations 14 AWG wire (1.5 mm² cross
sectional area, 21/0.30 PVC covered) is used to connect the
switches to the reversing control box.

2.2 Wiring
Plan the installation to suit the controls and give the operator a full
view of the windlass. The wiring system should be of the two cable
fully insulated return type, which avoids possible electrolytic
corrosion problems. We recommend the use of type III stranded,
tinned copper wire with copper crimp terminals. Most modern
installations are negative return (negative ground) but polarity
should be checked. If necessary add a grounding strap between
the mounting studs and an earthing point.
In a Model 1000 installation, the contactor must be sited in a
dry location.
DO NOT install the contactor in the anchor locker.
If a contactor is installed in an anchor locker it is exposed to harsh
conditions it is not designed to withstand. Furthermore this type
of installation will void your warranty.
Overload protection, in the form of the circuit breaker/isolator
supplied, must be built into the windlass wiring circuit. This
protects the wiring and prevents undue damage to the windlass
motor, in the event of its being stalled by an excessive load in
service.
It is advisable to site the circuit breaker/isolator in a dr y,
readily accessible place. The Breaker/ Isolator supplied must
be manually reset should an overload occur that causes it to trip
to the off position.
• NOTE: Crimp terminals should be used on all wire
ends wherever possible for good electrical contacts.
If you are not sure you understand these guidelines, seek
professional help.
2.3 Control Switch Installation
Follow the mounting instructions supplied with the switch.
Remember, in a Multi Station installation all switches must be
wired in a parallel circuit.
