The block provides two isolated groups of six ATO\/ATC blade fuse circuits each, making it suited either for wiring from two separate isolated batteries or for splitting a single battery into a mix of 24-hour (always-on) circuits and switched circuits. Each circuit is rated for up to 30 amps, with a total of 100 amps per block and a maximum voltage of 32V DC.\u003c\/p\u003e\u003cp\u003eWiring connects via screw terminals that accept ring terminals, with #8-32 screws and captive star lock washers securing the circuit connections and a #10-32 stud screw terminal on the negative bus. The block mounts using #8 screws (M4). Current-carrying buses and fuse clips are tin-plated copper for corrosion resistance and reliable conductivity, while one-piece stainless steel flange nuts secure the connections. A clear insulating cover snaps on with an easy-to-open push button latch, includes label recesses for circuit identification, and has built-in storage for two spare fuses. The cover satisfies ABYC\/USCG insulation requirements for enclosed electrical connections aboard a boat. Fuses are not included and are sold separately.\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 5032\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuits:\u003c\/strong\u003e 12 (two isolated groups of 6)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage:\u003c\/strong\u003e 100 amps per block, 30 amps per circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Voltage:\u003c\/strong\u003e 32 volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e #8 screw (M4)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNegative Bus Terminal:\u003c\/strong\u003e #10-32 stud\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Terminal Type:\u003c\/strong\u003e #8-32 screws with captive star lock washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Tin-plated copper bus and fuse clips; stainless steel flange nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCover:\u003c\/strong\u003e Clear insulating cover with label recesses and storage for two spare fuses\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e Meets ABYC\/USCG insulation requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.75 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eHow many circuits does the Blue Sea Systems 5032 fuse block have?\u003c\/strong\u003e The 5032 has 12 total ATO\/ATC blade fuse circuits, arranged as two isolated groups of six circuits each.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy is this called a split bus fuse block?\u003c\/strong\u003e The 5032 splits its 12 circuits into two electrically isolated buses, so it can be wired to two separate batteries or used to separate 24-hour circuits from switched circuits on a single battery.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the maximum amperage the 5032 fuse block can handle?\u003c\/strong\u003e The block is rated for 100 amps total, with each individual circuit rated up to 30 amps, at a maximum of 32 volts DC.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Blue Sea Systems 5032 come with fuses installed?\u003c\/strong\u003e No. Fuses are sold separately from the 5032 fuse block; the block itself includes storage space in the cover for two spare fuses.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size wire terminals does the 5032 use?\u003c\/strong\u003e Circuit connections use #8-32 screws with a captive star lock washer and accept ring terminals, while the negative bus uses a #10-32 stud terminal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the Blue Sea Systems 5032 fuse block mounted?\u003c\/strong\u003e It mounts using #8 screws (M4 equivalent).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 5032 fuse block ABYC and USCG compliant?\u003c\/strong\u003e Yes, the clear insulating cover on the 5032 satisfies ABYC\/USCG insulation requirements for boat wiring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material are the bus bars and fuse clips made of?\u003c\/strong\u003e The 5032 uses tin-plated copper bus bars and fuse clips, with one-piece stainless steel flange nuts securing the connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the cover on the 5032 work?\u003c\/strong\u003e The clear cover uses a push button latch for easy access to the fuses, includes label recesses for marking circuits, and has built-in storage for two spare fuses.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Blue Sea Systems 5032 fuse block weigh?\u003c\/strong\u003e The 5032 weighs 0.75 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 5032 be used with a single battery instead of two?\u003c\/strong\u003e Yes, the split bus design of the 5032 allows it to run off a single battery while still separating circuits into a 24-hour group and a switched group.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":48989499326683,"sku":"BSS-5032","price":83.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/5032.jpg?v=1784507476","url":"https:\/\/www.goodvibesmarina.com\/products\/blue-sea-systems-5032-st-blade-split-bus-fuse-block-12-circuit-dual-bus-with-ground-and-cover-ato-atc-100a-32v-dc","provider":"Good Vibes Marina","version":"1.0","type":"link"}
