Power & Protection

Build the Circuit From the Source Out

Start with battery layout, voltage, load, wire run, breaker or fuse rating, and the equipment being powered. Then choose parts that match the circuit and installation location.

Batteries Battery Switches Circuit Breakers Fuses

Lighting

Route Lighting by Location and Purpose

Navigation lights, cabin lights, deck lights, cockpit lights, courtesy lights, spotlights, replacement bulbs, and wiring accessories belong in distinct shopping paths.

All Lighting Navigation Lights Spotlights
1

Confirm Voltage

Check 12V, 24V, 32V, AC shore power, and the equipment being powered.

2

Match Load and Protection

Choose wire, breaker, fuse, terminal, and panel parts around the actual circuit load.

3

Check Fit and Exposure

Confirm mounting space, terminal style, panel cutout, water exposure, and service access.

Parts Desk Guidance

Electrical Fit Depends on the Whole System

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.

Why start with collections instead of search?

Collections group related electrical parts by system, which makes it easier to compare options before searching for an exact model or part number.

Can Marisol help identify electrical parts?

Yes. Send photos, part numbers, equipment model details, voltage, amperage, wire size, and the installation location.
