Blue Sea 1223 12V DC 12 Position Breaker Panel

The Blue Sea Systems 1223 is a 12-position 12V DC panel in a tall narrow format, 10.75 inches high by 4.88 wide by 3 deep.

The shape is the reason to pick this one. Tall and narrow fits vertical spaces beside a companionway or inside a locker where a wide panel simply will not go. Circuit count matters less than dimensions when the bulkhead available is the one the boat already has.

Twelve 7403 A-Series flat rocker 15A breakers come installed, filling every position rather than leaving spares. Maximum amperage is 100A per bus, though reaching that figure depends on correctly sized wire and fusing rather than being something to assume from the rating.

It belongs to a family running from 4 to 32 branch circuits, all with 15A breakers installed and available with voltmeters, ammeters or digital multimeters. That lets a boat carry the same appearance across several panels of different sizes. The 4205 square format label kit with 30 black square labels is included, and it weighs 4.85 pounds.
