MarinaGuard® series panels monitor for ground faults in feeder and branch circuits supplying electrical systems in marinas, boat yards, docking facilities, and similar locations. These panels satisfy the monitoring requirements of NEC 555.3 (2017 and earlier editions) and CEC 78-052 (2018 edition).

MarinaGuard® panels are available with single-channel monitoring, or twelve-channel monitoring from a single panel. Each circuit features an adjustable trip level to set below the maximum allowed, if desired. External current transformers are used for measuring ground-fault current and are available in a variety of sizes, shapes, and core types.

All models have a NEMA 4X, outdoor rated enclosure. A strobe light, mounted to the top of the enclosure, provides clear, visual trip indication. Relay contacts are provided for connecting external interruption equipment, such as shunt-trip breakers.
