It is designed with a stud-based terminal that provides direct terminal-to-bus contact for a low-resistance connection, and the bus itself is tin-plated copper (CDA 110\/UNS11000) for maximum conductivity and corrosion resistance. The base is molded from glass-reinforced polycarbonate rated UL 94-VO (self-extinguishing) to resist high heat, and the busbar ships with a press-on polycarbonate insulating cover that snaps onto the studs while leaving the wire terminals unobstructed for easy access. The raised bus design lets multiple wires land on a single screw terminal, simplifying circuits that need to share a common connection point.\u003c\/p\u003e\u003cp\u003eElectrically, the 2312 carries a continuous rating of 130 amperes AC and 150 amperes DC, with a maximum voltage rating of 300 volts AC and 48 volts DC. It has 20 positions total: stainless steel 1\/4\"-20 studs (torqued to 72 in-lbs, accepting a 1\/4\" or M6 ring terminal) along with stainless steel #8-32 screw terminals (torqued to 18 in-lbs, accepting a #8 or M4 ring terminal). This combination of stud and screw terminals allows both heavy main-circuit cables and smaller branch-circuit wires to be terminated on the same busbar.\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 2312\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Amperage (AC):\u003c\/strong\u003e 130 Amperes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Amperage (DC):\u003c\/strong\u003e 150 Amperes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Voltage Rating (AC):\u003c\/strong\u003e 300 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Voltage Rating (DC):\u003c\/strong\u003e 48 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions:\u003c\/strong\u003e 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBus Material:\u003c\/strong\u003e Tin-Plated Copper CDA 110\/UNS11000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Material:\u003c\/strong\u003e Glass Reinforced Polycarbonate, UL 94-VO Rated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCover Material:\u003c\/strong\u003e Polycarbonate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Terminals:\u003c\/strong\u003e Stainless Steel, 1\/4\"-20, torque 72 in-lbs, accepts 1\/4\" (M6) ring terminal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Terminals:\u003c\/strong\u003e Stainless Steel, #8-32, torque 18 in-lbs, accepts #8 (M4) ring terminal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Panel Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.57 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 632085023126\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the amperage rating of the Blue Sea Systems 2312 busbar?\u003c\/strong\u003e The 2312 is rated for 130 amperes continuous AC and 150 amperes continuous DC, with a maximum voltage rating of 300 volts AC and 48 volts DC.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 2312 come with a cover?\u003c\/strong\u003e Yes, the Blue Sea Systems 2312 includes a press-on polycarbonate insulating cover that attaches over the studs while still allowing unobstructed access to the wire terminals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many terminal positions does this busbar have?\u003c\/strong\u003e It has 20 positions total, combining stainless steel 1\/4\"-20 studs with stainless steel #8-32 screw terminals on the same bus.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size ring terminals fit the stud connections on the 2312?\u003c\/strong\u003e The 1\/4\"-20 stainless steel studs accept a 1\/4 inch (M6) ring terminal and should be torqued to 72 in-lbs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size ring terminals fit the screw terminals on the 2312?\u003c\/strong\u003e The #8-32 stainless steel screw terminals accept a #8 (M4) ring terminal and should be torqued to 18 in-lbs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the bus made from on the 2312?\u003c\/strong\u003e The bus is tin-plated copper (CDA 110\/UNS11000), chosen for high conductivity and resistance to corrosion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the base material heat resistant?\u003c\/strong\u003e Yes, the base of the Blue Sea Systems 2312 is glass reinforced polycarbonate rated UL 94-VO, meaning it is self-extinguishing and resists high heat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 2312 busbar weigh?\u003c\/strong\u003e The Blue Sea Systems 2312 weighs 0.57 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 2312 be used for both positive and negative common connections?\u003c\/strong\u003e The 2312 is a common busbar designed to consolidate multiple wires onto a single low-resistance point, and can be used as either a positive or negative distribution point in a DC electrical system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the 2312 and the version without a cover?\u003c\/strong\u003e The 2312 ships with a press-on insulating cover;
