Blue Sea 8381 DC Main + 32 Positions

The Blue Sea Systems 8381 DC Main + 32 Positions is a fully pre-wired electrical distribution panel engineered for DC power systems in marine, RV, mobile command, and expedition vehicles. This complete circuit breaker panel arrives with all positive, negative, and grounding buses installed and routed, eliminating the need for field wiring and reducing installation time significantly. The 8381 configuration includes a 100-amp C-Series main circuit breaker, 23 single-pole 15-amp branch breakers, an 8003 DC analog voltmeter, and an 8017 DC analog ammeter—delivering complete power monitoring and load distribution from a single integrated solution.

The panel's 32-position capacity accommodates multiple circuits without requiring secondary distribution panels, a critical advantage in space-constrained installations. White toggle switches enable mounting of up to three separate battery banks, allowing operators to isolate or combine power sources as mission parameters demand. The integrated analog meters provide real-time visibility into system voltage and current draw—essential data for load management in remote or off-grid applications where power reserves cannot be easily replenished. The panel is owner-upgradable to 24-volt operation, extending its service life across evolving vehicle platform standards and future-proofing capital investments.

This panel serves tactical mobility platforms, expedition vehicles, offshore vessels, emergency response units, and mobile command centers where reliable DC power distribution is non-negotiable. The main breaker protects the entire system from catastrophic fault conditions, while individual 15-amp branch breakers isolate individual loads—allowing the operator to maintain critical systems even if non-essential circuits fail. The pre-wired construction eliminates custom fabrication and the risk of improper circuit routing, critical considerations for operators who cannot afford downtime in the field.

Blue Sea Systems is the industry standard in marine and mobile electrical distribution, and the 8381 reflects decades of field-proven reliability in demanding environments. The modular architecture accepts future expansion without panel replacement, and the analog meter design provides reliable performance in high-noise electrical environments where digital displays may be vulnerable to induced noise or EMI.
