Four circuit positions, ATO blade fuses, and a 60-volt DC \/ 100-amp rating give you a clean, protected way to feed accessories. Stainless self-locking hardware and a latching cover mean it holds up where the spray gets to it.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've ever traced a mystery electrical fault on a boat, you already know the value of a proper fuse block. The Egis 8023-04 is a ring terminal fuse block and busbar kit that gives you a tidy, protected home for up to four DC accessory circuits. It mounts right at the battery, so your fused distribution starts where the power does. No long unprotected runs snaking through the bilge before they hit a fuse.\u003c\/p\u003e\n\u003cp\u003eHere's what you're working with. The block is rated for 60 volts DC and 100 amps, with four circuit positions that each take a standard ATO blade-style fuse. That covers 12-volt house systems with plenty of headroom, and it's comfortable on 24-volt and higher-voltage banks too. The negative busbars mount directly onto threaded-post battery terminals, so you get a clean common ground without a rat's nest of ring terminals stacked on one stud.\u003c\/p\u003e\n\u003cp\u003eThe whole thing is built for the environment it lives in. Egis calls it a harsh-environment design, and the hardware backs that up: stainless steel self-locking fasteners that won't back off with engine vibration or shake loose on a rough day offshore. A latching protective cover snaps over the top to keep spray, dropped tools, and curious fingers off the live terminals. The cover even has integrated label recesses, so you can mark what each circuit feeds and actually find it again six months later.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone wiring up a modest bank of accessories, bilge pump, nav lights, a stereo, a chartplotter, a livewell pump, and wanting each one on its own fuse. Ring terminals give you a far more reliable connection than push-in spades once you're bouncing across chop, and they don't vibrate loose. If you've been running accessories off an inline fuse holder taped behind the dash, this is the upgrade that makes the next troubleshooting session a five-minute job instead of an afternoon.\u003c\/p\u003e\n\u003cp\u003eA few honest notes on planning your circuits. The 100-amp figure is the total the block is built to handle, not per circuit, so budget your four loads to stay under it. In practice most accessory circuits pull a few amps each, so you'll rarely get close, but a high-draw item like a windlass or a big inverter belongs on its own dedicated feed, not sharing this block. Match each ATO fuse to the wire gauge and the device it protects, not to the appliance's peak draw. And it's good practice to put a single main fuse or breaker between the battery positive and everything downstream, this block included, so the whole feed is protected right at the source.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward. The negative busbars land on the battery's threaded posts, the block accepts your ring-terminal leads, and the stainless hardware locks it all down. Use DC-rated ATO fuses, which is what this block is designed around. Give yourself a little slack in the wiring so nothing is under strain, and check the connections after the first few outings, terminals settle in. A dab of dielectric grease on the exposed metal is cheap insurance against corrosion, especially on a saltwater boat.\u003c\/p\u003e\n\u003cp\u003eWhat's not in the box? Fuses. The block uses ATO blade fuses but you supply the values that match your circuits, which is the right call anyway since only you know what you're feeding. You get the fuse block, the busbar kit, the stainless self-locking hardware, and the latching cover in a retail pack. Add the fuses and your ring-terminal leads and you're wiring.\u003c\/p\u003e\n\u003cp\u003eEgis Mobile Electric has spent more than 25 years building electrical and battery-protection gear for marine, emergency, and fleet use, so this isn't a no-name block off a marketplace listing. It's a purpose-built piece of distribution hardware from a company that does this for a living. For a clean, fused, corrosion-minded accessory setup that starts right at the battery, the 8023-04 earns its spot.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eRated 60 volts DC and 100 amps total, with enough headroom for 12V, 24V, and higher-voltage banks\u003c\/li\u003e\n  \u003cli\u003eFour ATO blade-style fuse positions, so each accessory circuit gets its own fuse\u003c\/li\u003e\n  \u003cli\u003eNegative busbars mount directly on threaded-post battery terminals for a clean common ground\u003c\/li\u003e\n  \u003cli\u003eRing-terminal connections stay tight through vibration and chop, unlike push-in spade fittings\u003c\/li\u003e\n  \u003cli\u003eStainless steel self-locking hardware resists backing off from engine vibration and corrosion\u003c\/li\u003e\n  \u003cli\u003eLatching protective cover keeps spray, tools, and fingers off the live terminals\u003c\/li\u003e\n  \u003cli\u003eIntegrated label recesses in the cover let you mark and identify each circuit\u003c\/li\u003e\n  \u003cli\u003eHarsh-environment design built for saltwater and marine use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Egis Mobile Electric reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow many circuits does the 8023-04 support?\u003c\/summary\u003e\n    \u003cp\u003eFour.
