Rated 150 amps at 48 volts DC, it distributes high and low amperage loads from a single bar. Tin-plated copper, stainless self-locking hardware, and an included clear insulated cover make it a clean, safe hub for your boat's DC system.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Egis CommonBus 6151-210 gives you one clean, central place to distribute DC power on your boat. It's a flat-strip busbar with two 1\/4-inch studs for your heavy feeds and ten #8 screw terminals for everything smaller. Rated at 150 amps and 48 volts DC, it's built to be the tidy hub behind your helm or inside the battery compartment where a rat's nest of ring terminals used to live.\u003c\/p\u003e\n\u003cp\u003eHere's what makes the mixed terminal layout so handy. The two tin-plated copper studs take your main positive or negative feed, or a big load like a windlass or an inverter run. The ten screw terminals handle the rest, your electronics, bilge pumps, cabin lights, chartplotter, VHF, and accessory circuits. One bar, a wide range of outputs, high and low amperage all coming off the same point. That's the whole idea behind a common bus, and it's why these show up in so many clean installs.\u003c\/p\u003e\n\u003cp\u003eThe 48-volt DC rating is worth calling out. It means this bar is at home on a 12-volt system, a 24-volt system, or a 48-volt bank. If you're running a modern lithium house bank, a bow-mount trolling motor setup, or a higher-voltage accessory system, the 6151-210 covers you without stepping outside its rating. 150 amps gives you real headroom for a mid-size distribution point.\u003c\/p\u003e\n\u003cp\u003eCorrosion is the enemy on the water, so the details matter. The bar itself is tin-plated copper, which keeps conductivity high while fighting off the oxidation that eats bare copper in a salt-air bilge. The hardware is stainless steel and self-locking, so it stays torqued down through engine vibration and a season of pounding across chop. You won't be back there every spring chasing loose nuts.\u003c\/p\u003e\n\u003cp\u003eSafety is built in too. The 6151-210 ships with a clear, snap-on insulated cover. It keeps a dropped wrench or a stray finger off live terminals, and because it's transparent you can still eyeball your connections without pulling it. In a tight console or a battery box where metal tools and live studs share the same small space, that cover earns its keep.\u003c\/p\u003e\n\u003cp\u003eAnd it's compact. At 5.86 inches long and 1-1\/4 inches wide, the flat strip mounts flush against a bulkhead, a panel, or the side of a battery compartment. It slips into spots where a bigger distribution block simply won't fit, which is exactly what you want when you're rigging a center console or a smaller cruiser with limited real estate behind the dash.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward. Land your main feed on one of the studs, torque the stainless hardware down, and run your branch circuits to the screw terminals. Because the self-locking nuts hold their setting, your torque values stay put between haul-outs. Snap the cover back on when you're done and you've got a distribution point that looks factory and holds up season after season.\u003c\/p\u003e\n\u003cp\u003eOne honest note so you rig it right. This is a distribution busbar, not a fuse block. It ties your circuits to a common point cleanly and safely, but it doesn't provide any circuit protection on its own. Plan to fuse your feeds and branch circuits separately, the way ABYC wiring practice calls for. Do that, and the CommonBus becomes the neat, dependable backbone of your boat's DC system.\u003c\/p\u003e\n\u003cp\u003eWho's it for? Anybody tidying up a helm, adding electronics, or building out a battery bank who wants their positive and negative connections landing in one organized, protected spot instead of stacked six-deep on a single stud. It's the kind of small, well-made part that quietly makes the whole install easier to troubleshoot down the road, because every circuit lands somewhere you can see and reach. Run a matching pair, one for positive and one for negative, and your DC wiring goes from a headache to something you're actually proud to open the hatch on.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e48 Volt DC rating with 150 Amp capacity handles 12V, 24V, and 48V marine electrical systems\u003c\/li\u003e\n  \u003cli\u003eTwo 1\/4-inch tin-plated copper studs for heavy main feeds and high-current loads like windlasses and inverters\u003c\/li\u003e\n  \u003cli\u003eTen #8 screw terminals distribute power to electronics, pumps, lighting, and accessory circuits\u003c\/li\u003e\n  \u003cli\u003eTin-plated copper construction keeps conductivity high and resists corrosion in salt air\u003c\/li\u003e\n  \u003cli\u003eStainless steel self-locking hardware stays tight through engine vibration and won't back out\u003c\/li\u003e\n  \u003cli\u003eIncluded clear insulated cover guards against accidental shorts and shock while staying see-through\u003c\/li\u003e\n  \u003cli\u003eCompact 5.86-inch by 1-1\/4-inch flat-strip footprint fits tight console and battery-compartment spaces\u003c\/li\u003e\n  \u003cli\u003eFlat strip design mounts flush against a bulkhead or panel for a factory-clean install\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\u003eWhat is the amperage and voltage rating of the 6151-210?\u003c\/summary\u003e\n    \u003cp\u003eIt's rated for 150 amps at 48 volts DC.
