Each of the four screw pairs forms its own independent circuit, so multiple accessories or feeds can share a single mounting location without interacting electrically. The block carries a 30 Amp, 600 Volt AC\/DC rating per circuit and uses M4 (#8) terminal studs, making it suitable for a range of onboard DC and AC wiring tasks where reliable, code-compliant termination is needed.\u003c\/p\u003e\u003cp\u003eA closed-back design fully insulates the live power connections from the mounting surface, reducing the risk of accidental grounding or short circuits when the block is surface-mounted to a panel or bulkhead. If a project calls for tying circuits together into a common bus, Blue Sea Systems jumpers 5035 and 5037 (sold separately) snap across the terminal pairs to combine independent circuits as needed. The 2504 measures 3.25 inches (82.60 mm) overall with a 2.81 inch (71.40 mm) mounting hole spacing, and weighs 0.17 pounds.\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 2504\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Circuits:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 30 Amps per circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600 Volts AC\/DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Stud Size:\u003c\/strong\u003e M4 (#8)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3.25 inches (82.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Spacing:\u003c\/strong\u003e 2.81 inches (71.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Surface mount, closed-back design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 632085025045\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 2504 terminal block have?\u003c\/strong\u003e The Blue Sea Systems 2504 has 4 independent circuits, with each screw pair forming its own isolated circuit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the current rating of the 2504 terminal block?\u003c\/strong\u003e Each circuit on the Blue Sea Systems 2504 is rated for 30 Amps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage is the 2504 terminal block rated for?\u003c\/strong\u003e 600 Volts AC\/DC is the rating for each circuit on the 2504 terminal block.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size terminal studs does the 2504 use?\u003c\/strong\u003e M4 (#8) terminal studs are used on the Blue Sea Systems 2504.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan circuits on the 2504 be connected together?\u003c\/strong\u003e Yes, Blue Sea Systems jumpers 5035 and 5037 (sold separately) can be added across terminal pairs on the 2504 to combine independent circuits into a common bus.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the 2504 have a closed-back design?\u003c\/strong\u003e The closed-back design on the 2504 fully insulates the live power terminals from the mounting surface, preventing accidental grounding or shorts against a metal panel or bulkhead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Blue Sea Systems 2504?\u003c\/strong\u003e The 2504 measures 3.25 inches (82.60 mm) in overall length with a mounting hole spacing of 2.81 inches (71.40 mm).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 2504 terminal block weigh?\u003c\/strong\u003e The Blue Sea Systems 2504 weighs 0.17 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 2504 terminal block made from?\u003c\/strong\u003e The 2504 is made from plastic.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs each screw pair on the 2504 electrically isolated?\u003c\/strong\u003e Yes, on the Blue Sea Systems 2504 each screw pair is one isolated circuit, keeping the 4 circuits electrically separate unless jumpered together.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 2504 be used for both AC and DC wiring?\u003c\/strong\u003e Yes, the 2504 is rated for 30 Amps at 600 Volts AC\/DC, so it can be used on both AC and DC circuits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 2504 designed for surface mounting?\u003c\/strong\u003e Yes, the Blue Sea Systems 2504 is a surface-mount terminal block with a closed-back design that insulates it from the mounting surface.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":48989488546011,"sku":"BSS-2504","price":8.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/2504.jpg?v=1784507382","url":"https:\/\/www.goodvibesmarina.com\/products\/blue-sea-systems-2504-terminal-block-4-circuit-30a-600v-8-stud","provider":"Good Vibes Marina","version":"1.0","type":"link"}
