It is built to accept both 5\/16 inch and 3\/8 inch stud connections, giving installers flexibility when stacking multiple ring terminals on a single post. The 2018 is also designed for outboard engine installation, making it a practical choice when factory battery cables need to be extended to reach a relocated battery or accessory panel.\u003c\/p\u003e\u003cp\u003eEach PowerPost uses one-piece serrated flange nuts that bite into the ring terminal for a correct, secure, and vibration-resistant connection, reducing the chance of a loose terminal working free over time. The connector body is molded from blue plastic for corrosion resistance and easy circuit identification, while the post and contact surfaces are copper for reliable conductivity. The connector is not amperage-rated as a standalone part; the amperage that flows between terminals stacked on the post is determined by the gauge of wire and the terminals used in the connection. It carries a maximum operating voltage of 48 volts DC and uses #10 (M5) screws.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 2018\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Sizes:\u003c\/strong\u003e 5\/16 Inch and 3\/8 Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size:\u003c\/strong\u003e #10 (M5)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Voltage:\u003c\/strong\u003e 48 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e Not rated - amperage flows between terminals stacked on post and is determined by wire and terminals used\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating:\u003c\/strong\u003e 257 degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.35 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 632085020187\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal marine battery post application; suited to outboard engine installations where factory cables need extending, and to any 12 volt or lower DC system where the maximum 48 volt DC operating rating is not exceeded.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are specified for this part.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Blue Sea Systems PowerPost 2018 used for?\u003c\/strong\u003e The PowerPost 2018 connects high amperage conductors at a single terminal post, and it is also designed for outboard engine installations where factory battery cables need to be extended.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat stud sizes does the 2018 PowerPost accept?\u003c\/strong\u003e It accepts both 5\/16 inch and 3\/8 inch stud connections, so ring terminals sized for either stud can be stacked on the same post.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the PowerPost 2018 amperage rated?\u003c\/strong\u003e No, the connector itself is not amperage-rated.
