Shore Power Connection Locking Devices

Overview

Disconnection of the shore power supply to a vessel, or theft of power from a metered supply can be a problem for boat owners.

If the vessel's shore power supply is disconnected by someone wanting access to power, then subsequently not reconnected, the result is often a freezer that thaws wasting food. A battery charger that can no longer keep batteries charged. An inverter that tries to maintain the AC power supply to the vessel by drawing off the ships batteries and eventually flattening them. Or any number of other undesirable consequences. Some vessels, because of the earthing requirements for inverters and generators, will trip an RCD breaker if the power isn't restored to the vessel in a particular sequence.

These are all inconvenient consequences that can be easily avoided. The illustrations here show a locking device for common 16 amp, 3 pin, IP67 rated, marina shore power outlets complying with IEC-60309. First designed in 2001 for a different application, these devices have been proven to provide an effective deterrent against unauthorised use of a shore power supply. These devices are also available to fit other outlet and plug types.
