MarinaGuard® series Listed Ground-Fault 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 555.35, 555.53 & 682.15 (2020 & 2023 editions), and CE Code requirements for similar locations.

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 at or below the maximum allowed, if desired. External current transformers, installed in the site electrical equipment, are used for measuring ground-fault current and are available in a variety of circular and rectangular sizes.

All models have a Type 4X, outdoor rated enclosure with a “weep” outlet to mitigate condensation formation. 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.
