Power Transfer Switch; Switching Between Dock/Park Power Source And A Boat Generator Or Inverter; Automatic; 125/250 Volt AC; 50 Amp; Vibration Resistant Brass Terminals

High copper content brass terminals reduce operating temperature, increase conduction, and improve safety. A direct connection to the safety interlock contacts provides less resistance in the circuit which reduces heat, improves thermal and electrical conductivity, and reduces the risk of a thermal event. The mechanical safety interlock prevents generator and shore power sources from connecting simultaneously and provides a stronger terminal contact. Features & Benefits Designed To Withstand Vibration From RV Reduces The Risk Of Loose Terminals Arcing Improved Thermal And Electrical Conductivity Less Resistance In The Circuit Reducing Heat Mechanical Safety Interlock Prevents Generator And Shorepower Source From Contacting At The Same Time And Provides Stronger Terminal Contact Fire Resistant Plastic Casing Better Quality And Thicker Silver Contacts For Longer Durability In Service Multiple Cable Strain Punch Out Holes For Easier And More Installation Options
