Tin-plated copper connectors, a phenolic body, and screw terminals rated to 30 amps and 240 volts AC\/DC. It's the clean, serviceable way to land multiple feeds or grounds in one organized junction instead of a mess of crimp connectors behind the dash.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Egis Mobile Electric 2230-04 is a 4-circuit terminal block, the kind of unassuming part that quietly holds a clean electrical system together. You get tin-plated copper connectors, a phenolic body, and screw terminals rated to 30 amps and 240 volts AC\/DC. Four independent circuits in a compact 3.2 by 1.3 inch footprint. It's not glamorous. But it's exactly what separates a boat you can troubleshoot at the dock from one that fights you every time an accessory acts up.\u003c\/p\u003e\n\u003cp\u003eSo what does a terminal block actually do? It gives every wire a home. When you're rigging accessories, lights, pumps, electronics, a stereo, you need an organized place to land those wires instead of chaining butt connectors together behind the dash. This block lets you feed several circuits from a single source, or gather several grounds into one common point. Everything lands on a screw terminal you can reach, test, and service. And when something does go wrong two seasons from now, you'll thank yourself for the tidy layout.\u003c\/p\u003e\n\u003cp\u003eThe connectors are tin-plated copper, and on a boat that matters more than it sounds. Salt air goes after bare copper fast. Corrosion creeps in, resistance climbs, connections heat up, and eventually you're chasing a voltage drop that has nothing to do with the device you're blaming. Tin plating shrugs off that corrosion. It keeps the metal-to-metal contact clean and the resistance low, so the power your battery sends actually reaches the load. That's the whole point of using marine-grade parts instead of whatever's in the automotive aisle.\u003c\/p\u003e\n\u003cp\u003eThe body is phenolic, a rigid, heat-resistant plastic that doesn't conduct and doesn't soften when a circuit is pulling real current. Push 30 amps through a cheap block and you can watch it warp. This one holds its shape. The screw terminals themselves are simple and honest. Strip your wire or crimp on a ring terminal, set it under the screw, and torque it down. No special tool, no proprietary connector, no guesswork. If you ever need to add a circuit or move a wire, it's a two-minute job with a screwdriver.\u003c\/p\u003e\n\u003cp\u003eEach circuit is rated to 30 amps, which covers the vast majority of accessory and sub-distribution loads on a typical boat. The 240 volt AC\/DC rating means it's happy on any common DC system you'll run, 12 volt, 24 volt, or 32 volt, and it's rated for AC service too. Four circuits give you room to organize a small distribution panel, split a feed to a bank of switches, or consolidate grounds without stacking a dozen ring terminals on one stud. Think of it as one neat row where every wire is accounted for, instead of a bundle you have to trace by hand.\u003c\/p\u003e\n\u003cp\u003eWhere does it go? Somewhere dry-ish and accessible, mounted flat to a bulkhead, a panel back, or inside an electrical box. Keep it out of standing bilge water and direct spray if you can. It's designed to be screwed down through its base, so plan on a couple of appropriate marine-grade fasteners. We don't list included mounting screws, so grab what suits your surface. Wire it with ring terminals for the most secure landings, label each circuit, and never run more than 30 amps through any one position.\u003c\/p\u003e\n\u003cp\u003eThis is a workmanlike part from a company that builds marine electrical gear for a living. Egis Mobile Electric has spent decades making power distribution and battery protection equipment for boats, emergency vehicles, and other demanding installs. If you're wiring a boat right the first time, or cleaning up a previous owner's mess, the 2230-04 is a small, honest piece of the puzzle that earns its keep for years. It's the sort of part you install once and never think about again, which is exactly what you want from your electrical system.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eFour independent circuits for landing multiple feeds or grounds in one organized junction\u003c\/li\u003e\n  \u003cli\u003eTin-plated copper connectors resist salt-air corrosion and keep connection resistance low\u003c\/li\u003e\n  \u003cli\u003e30 amp per-circuit rating handles accessory and sub-distribution loads on most boats\u003c\/li\u003e\n  \u003cli\u003eRated to 240 volts AC\/DC, covering 12, 24, and 32 volt marine systems\u003c\/li\u003e\n  \u003cli\u003eScrew terminal connections for fast, serviceable landings with just a screwdriver\u003c\/li\u003e\n  \u003cli\u003ePhenolic body is heat-resistant and non-conductive for safe high-current use\u003c\/li\u003e\n  \u003cli\u003eCompact 3.2 inch by 1.3 inch footprint fits tight panels and console spaces\u003c\/li\u003e\n  \u003cli\u003eBlack finish blends into panel, bulkhead, and bilge installations\u003c\/li\u003e\n  \u003cli\u003eBuilt by Egis Mobile Electric, a marine electrical specialist with 25-plus years in the field\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 this terminal block have?\u003c\/summary\u003e\n    \u003cp\u003eFour independent circuits.
