Blue Sea 3119 Surface Mount 50A ELCI Panel Enclosure

The Blue Sea Systems 3119 is a surface mount enclosure with a 120/240V AC 50A ELCI main and one blank position, weighing 7 pounds.

Fifty amp shore service is the reason for this one, putting considerably more through the main than a 30A hookup does. It also means the enclosure is heavy at 7 pounds, and a proper backing plate belongs behind it rather than trusting a thin bulkhead skin to hold it.

Blue Sea publishes more installation detail here than on most enclosures. Rated operating range is -35°C to 66°C, cover hardware is 10-32 stainless, and mounting takes 1/4 inch diameter #12 fasteners. That temperature range matters where the enclosure goes somewhere unheated or exposed rather than in a conditioned space.

The blank position takes Carling Technologies A and C Series flat rocker or ELCI main breakers, and the box is glass filled polycarbonate with a clear overlapping cover. An oversized polyurethane gasket formed in place seals it, the stainless hinge pin is removable, and five waterproof glands, labels, hardware and the manual are included. Mount within 10 feet of the inlet for ABYC E-11. Explore more marine electrical panels.
