It provides six 5\/16-18 terminal studs, giving installers room to gang together battery cables, fuse holders, and circuit leads at one central point instead of stacking connections on a single post. The bus bar is rated for a maximum voltage of 300V AC \/ 48V DC with a continuous current rating of 250A AC\/DC, making it suitable for higher-current distribution points such as battery banks, charging systems, or main power buses.\u003c\/p\u003e\u003cp\u003eConstruction uses tin-plated pure electrical copper for the conductive bus, which maximizes conductivity while resisting corrosion in the marine environment, mounted on a UL 94-V0 rated base material that resists high heat. The bus bar mounts using two mounting holes sized to accept #10 (M5) screws, allowing it to be secured to a panel, bulkhead, or existing mounting surface. With six studs sharing one continuous bus, every stud is electrically common, so this is a shared bus point rather than a set of isolated circuits. This makes the 2126 a practical choice for consolidating grounds, positive distribution, or bonding points where multiple cables need to land on the same electrical potential.\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 2126\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e MaxiBus BusBar, 6 Stud\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Studs:\u003c\/strong\u003e 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Stud Size:\u003c\/strong\u003e 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Voltage:\u003c\/strong\u003e 300V AC \/ 48V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 250A AC\/DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Holes:\u003c\/strong\u003e 2, sized for #10 (M5) screws\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Material Rating:\u003c\/strong\u003e UL 94-V0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Material:\u003c\/strong\u003e Tin-plated pure electrical copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 632085021269\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the current rating of the Blue Sea Systems 2126 MaxiBus BusBar?\u003c\/strong\u003e The 2126 MaxiBus BusBar carries a continuous rating of 250A AC\/DC with a maximum voltage of 300V AC \/ 48V DC.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many terminal studs does the 2126 busbar have?\u003c\/strong\u003e It has 6 terminal studs, each sized 5\/16-18, all sharing one common electrical bus.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre all six studs on the Blue Sea Systems 2126 electrically connected?\u003c\/strong\u003e Yes, all six studs on the 2126 are tied to a single continuous bus, so they share the same electrical potential rather than functioning as isolated circuits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size screws are needed to mount the 2126 BusBar?\u003c\/strong\u003e The 2126 has two mounting holes sized to accept #10 (M5) screws.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Blue Sea Systems 2126 busbar made from?\u003c\/strong\u003e The conductive bus is tin-plated pure electrical copper for maximum conductivity and corrosion resistance, mounted on a UL 94-V0 rated base material that resists high heat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 2126 MaxiBus BusBar weigh?\u003c\/strong\u003e The Blue Sea Systems 2126 weighs 0.8 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Blue Sea Systems 2126?\u003c\/strong\u003e The UPC for the 2126 MaxiBus BusBar is 632085021269.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 2126 be used for AC and DC circuits?\u003c\/strong\u003e Yes, the 2126 is rated for both AC and DC use, with a maximum of 300V AC or 48V DC and a continuous rating of 250A AC\/DC.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size cable lugs fit the studs on the 2126?\u003c\/strong\u003e The 2126 uses 5\/16-18 terminal studs, so ring terminals or lugs sized for a 5\/16 inch stud will fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Blue Sea Systems 2126 come with a cover?\u003c\/strong\u003e The 2126 is the bare 6-stud MaxiBus BusBar without a cover.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a MaxiBus BusBar used for on a boat?\u003c\/strong\u003e A MaxiBus BusBar like the Blue Sea Systems 2126 is used to consolidate multiple electrical connections, such as battery cables or circuit leads, onto one common terminal point instead of stacking them on a single post.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":48989479960795,"sku":"BSS-2126","price":70.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/2126.jpg?v=1784507356","url":"https:\/\/www.goodvibesmarina.com\/products\/blue-sea-systems-2126-maxibus-250a-busbar-6-x-5-16-18-studs-tin-plated-copper-no-cover","provider":"Good Vibes Marina","version":"1.0","type":"link"}
