Blue Sea Systems Electrical Panels

The electrical panel is the heart of a boat wiring system. Blue Sea Systems builds trusted marine panels that distribute and protect power on recreational vessels. This collection includes DC panels, AC panels, AC and DC combo panels, and ELCI main panels that combine breakers and meters in one unit. Selecting the correct panel starts with identifying the type of power you need to control, the number of circuits required, and the safety devices your installation must include.

DC, AC, or combo panels

A DC panel manages 12 volt or 24 volt circuits that power lights, bilge pumps, navigation electronics, and other low voltage equipment. An AC panel handles 120 volt power from shore cords or onboard generators. Combo panels place both AC and DC sections on the same faceplate while keeping the two systems electrically isolated. Choose the panel type that matches the systems already on your boat and never place AC and DC circuits behind the same breakers.

Count circuits and plan for growth

Panels are offered in standard sizes such as eight, twelve, or sixteen positions. Count every circuit you use today and then add at least two or three spare positions for equipment you may install later. Running out of positions often leads to the added cost and complexity of mounting a second panel, so allow extra space from the beginning.

ELCI protection on shore power

ABYC standards now require Equipment Leakage Circuit Interrupter protection on many shore power installations. An ELCI main trips when it detects leakage current that could create a shock hazard in the water. Panels that include a built in 30 amp ELCI main combine this primary protection with the branch circuit breakers in a single enclosure, which reduces wiring time and keeps the installation compact.

Meters for system monitoring

Panels with analog or digital voltmeters and ammeters let you check battery voltage and current draw without additional instruments. On boats that rely on a house battery bank, this built in metering helps you notice a voltage drop before the batteries become too low to start the engine or run essential equipment at anchor.

Physical fit and installation

Measure the cutout height, width, and the depth behind the mounting surface before you order. Breakers and wiring require clearance, and some panels need extra space for the ELCI module. Place frequently used switches where crew members can reach them without stretching across the helm or companionway.

If you are unsure which panel matches your boat, provide our technical staff with your AC and DC circuit counts and whether you use shore power. We can recommend the correct panel type, position count, ELCI rating, and metering options so the finished system meets safety standards and remains easy to use.
