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.
Search Fallback
Use Search When You Know the Part Number or Exact Term
Search is useful for exact matches like a breaker rating, wire gauge, charger model, bulb type, or OEM number. For browsing, use the full collections above first.
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.
