Confirm Voltage

Match components to the system voltage and equipment requirements before replacing switches, breakers, chargers, lights, or accessories.

Size for the Load

Breakers, fuses, wire, terminals, and panels should be sized around circuit load, wire length, wire gauge, and installation location.

Electrical Fitment Depends on the Whole Circuit

A part that looks similar may not be right for the circuit. Before ordering, confirm the device, voltage, amperage, wire size, terminal type, mounting space, ignition-protection needs, and wet-location exposure.

Electrical Accessories FAQ

Choosing Marine Electrical Parts

What should I check before replacing a breaker or fuse?

Confirm voltage, amperage, wire gauge, circuit load, fuse or breaker style, terminal type, and panel fit before ordering.

Why use tinned marine wire?

Tinned marine wire is built to resist corrosion better than general-purpose wire, which helps in damp and salt-air environments.

Can I add USB chargers or phone mounts at the helm?

Yes, but the charger should be protected by the correct fuse or breaker and installed with suitable wiring, terminals, and weather protection.

Can the Parts Desk help identify electrical parts?

Yes. Send photos, part numbers, equipment model information, voltage, amp rating, wire size, and installation location.
