Blue Sea Systems SMS 120V AC ELCI 30A Enclosure

The ELCI (Equipment Leakage Circuit Interrupter) is a ground-fault circuit interrupter for equipment. On a boat, it is critical because it detects current leakage to ground, protecting people from electric shock and preventing fire hazards. It is essential for compliance with marine safety standards, including ABYC E-11.

The primary function of this panel is to distribute AC power and protect the entire marine electrical system. It includes a 30A/120V AC equipment leakage circuit interrupter (ELCI), providing essential protection for shore power.

Nominal voltage: 120V AC

Main ELCI breaker rated current: 30A

Protection type: Equipment Leakage Circuit Interrupter (ELCI)

The speaker enclosure is made from a base of glass-reinforced polycarbonate. This material provides high resistance to harsh marine environments.

The external dimensions of the panel are 192 mm x 188 mm x 120 mm (7.6" x 7.4" x 4.7").

This panel is designed to operate within a temperature range from -35°C to 66°C.

The abbreviation "SMS" stands for "Surface Mount System", indicating that the panel is designed for surface-mounted installation.

The panel has three blank circuit positions, allowing customization with additional circuit breakers as required by the installation.

Yes, the panel is designed for marine environments. It meets IP66 and NEMA 4x waterproofing standards, providing excellent resistance to water and dust.

The main ELCI protection of 30A means that the panel’s main circuit breaker can handle a maximum current of 30 amperes and includes earth-leakage protection. This rating is typical for 120V AC shore-power systems.

No, the panel is supplied with three blank circuit positions. Circuit breakers for these positions must be purchased separately and added to customize the installation.

This panel is designed for surface mounting (Surface Mount System).

The panel is an enclosure with a main ELCI circuit breaker and blank positions. It requires full wiring for integration into the boat's electrical system, including shore power and distribution circuits.

To maintain IP66 and NEMA 4x waterproofing after cable installation, it is critical to use appropriate cable glands or seals for all cable entries and exits, and to ensure all openings are properly sealed.

The external dimensions of the panel are 192 mm x 188 mm x 120 mm. It is recommended to allow additional space around the panel for easier wiring, ventilation, and maintenance access.

No, this panel is specifically designed for 120V AC electrical systems, as indicated by its designation "120VAC ELCI 30A". It is not compatible with 240V AC systems.

Yes, this panel includes a main 30A/120V AC ELCI, essential for ABYC E-11 compliance regarding shore power protection for the entire boat. ABYC E-11.11.1 compliance has been mandatory since January 1, 2013.

The context does not specify compatibility with circuit breakers from different brands. It is generally recommended to use circuit breakers compatible with the specifications of the panel and the Blue Sea Systems brand to ensure optimal performance and safety.

Yes, thanks to its base made of fiberglass-reinforced polycarbonate and its IP66 and NEMA 4x waterproofing standards, this panel is designed to withstand marine environments, including use on boats in fresh water and salt water.
