Shore-Power Boat Fire Protection
Prime Technology's ShIP helps prevent onboard electrical fires.
With the increased demand to have all the electrically powered comforts of home onboard, it should come as no surprise to boaters that the majority of AC-related electrical fires involve overheated shore-power plugs and receptacles. Prime Technology, aims to change all that with the introduction of its Shore Power Inlet Protector (ShIP for short), a monitoring and alarm device that automatically disconnects AC shore power when excessive heat is detected at the power inlet connector. We reviewed the ShIP 110 designed for use with a 110-volt, 30-amp system. The company also offers a similar unit (the ShIP 220) for use with 220-volt, 50-amp service. Charred plugs and receptacles are the result of resistance build-up (due to loose or corroded connections), which generates heat and the potential for fire, a problem especially prevalent among vessels that continually run high energy loads such as water heaters and air-conditioning units. In addition to monitoring the temperature of your vesselís shore-power inlet plug and its wiring, the ShIP system automatically disconnects AC shore power when an unsafe temperature is detected, providing visual and audible alarms. (The audible alarm shuts down after five minutes to avoid prolonged disturbance to surrounding boats.)
