Blue Sea 3116 - SMS Panel Enclosure w/ELCI (30A) and 3 Blanks - 120V

The Blue Sea 3116 SMS Panel Enclosure with ELCI (30A) and 3 Blanks is a marine AC electrical distribution system engineered to meet ABYC E-11 standards when installed with an ELCI main circuit breaker within 10 feet of shore power inlets. This 120V panel enclosure is purpose-built to handle Equipment Leakage Circuit Interrupter main breakers and other large-frame devices, providing the electrical safety backbone modern boats require for compliant AC power management.

The enclosure features a durable glass-filled polycarbonate base with a clear cover, allowing easy monitoring of breaker status while protecting internal components from salt spray, humidity, and vibration. Three blank apertures enable customized breaker loading according to your vessel's specific power distribution requirements. The 30-amp ELCI rating suits mid-sized cruising sailboats and powerboats where shore power protection must meet modern electrical codes. Weighing 3.7 lbs and measuring 9 × 6 × 9 inches, the 3116 fits standard panel mounting locations without requiring extensive electrical system reconfiguration.

This panel enclosure addresses the critical safety concern all boat owners face: protecting AC circuits from ground faults and leakage current that can cause electrolysis, equipment damage, or crew injury. Weekend fishermen upgrading older cabins and serious cruisers planning extended offshore passages both rely on ELCI protection as a non-negotiable component of safe AC power systems. The 3116 represents the practical solution for vessels that cannot operate without compliant shore power protection and need expansion capacity for future circuit additions.
