It lets you choose which battery bank powers starting and charging, or combine both batteries in parallel operation, and the built-in key lock prevents unauthorized or accidental switching once a position is set. The switch body is molded polycarbonate with brass terminals for corrosion resistance, and it is ignition protected for safe use in gasoline engine spaces.\u003c\/p\u003e\u003cp\u003eElectrically, the 8502DP is rated for 6 to 50 Volt marine electrical systems and handles up to 250 Amps continuous or 360 Amps intermittent load, covering the demands of most recreational and light commercial boat electrical systems. Terminals accept a 3\/8 inch stud connection. The switch measures 5-1\/4 inches in diameter with a 2-5\/8 inch mounting depth, sized for standard helm or engine bay panel mounting. For dual engine boats, Perko recommends installing two switches, one per engine, to manage each battery bank independently. The red finish provides clear visual identification at the helm or in the engine compartment.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Perko\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 8502DP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Lock:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eField Disconnect:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 5-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth:\u003c\/strong\u003e 2-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.91 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polycarbonate body with brass terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 6 to 50 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 250 Amps continuous, 360 Amps intermittent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Stud Size:\u003c\/strong\u003e 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Protected:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 085226559624\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal for marine electrical systems using two or more 6 to 50 Volt batteries, including single and dual engine boats.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are listed for this part.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the key lock on the Perko 8502DP do?\u003c\/strong\u003e The key lock on the Perko 8502DP battery selector switch lets you lock the switch in a chosen position, preventing it from being bumped or turned by unauthorized users while the boat is unattended.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many amps can the 8502DP handle?\u003c\/strong\u003e The Perko 8502DP is rated for 250 Amps continuous and 360 Amps intermittent, and it is designed for 6 to 50 Volt marine electrical systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size are the terminal studs on this switch?\u003c\/strong\u003e The terminal studs on the Perko 8502DP battery selector switch are 3\/8 inch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Perko 8502DP?\u003c\/strong\u003e This switch measures 5-1\/4 inches in diameter with a 2-5\/8 inch mounting depth.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Perko 8502DP weigh?\u003c\/strong\u003e The Perko 8502DP battery selector switch weighs 0.91 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Perko 8502DP ignition protected?\u003c\/strong\u003e Yes, the 8502DP is ignition protected, making it suitable for installation in gasoline engine compartments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need two switches for a dual engine boat?\u003c\/strong\u003e Yes, for dual engine systems Perko recommends using two 8502DP switches, one for each engine's battery bank.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the Perko 8502DP and 8501DP?\u003c\/strong\u003e The 8502DP includes a key lock feature, while the 8501DP is the same size switch without a key lock.
