<h3>SmartPlug: Reinventing Shore Power Safety for Marine &amp; RV Applications</h3><p>Founded in 2007 in Seattle, Washington, SmartPlug set out to solve one of the most persistent hazards in boating and RV ownership: unreliable shore power connections. Traditional twist-lock connectors — largely unchanged since the 1930s — are notorious for developing loose connections and corrosion over time, two of the leading causes of electrical fires at marinas and campgrounds. SmartPlug was built from the ground up to change that.</p><h3>A Patented System Built Around Safety</h3><p><strong>SmartPlug's shore power system</strong> replaces the aging twist-type design with an intuitive, straight-in connector that locks securely using side clips rather than relying on a threaded collar. The result is a system that delivers dramatically more electrical contact area than conventional connectors, a multi-point locking mechanism, and triple weatherproof seals that keep moisture, salt spray, and dust out of the housing — the very conditions that cause corrosion and connection failures.</p><p>The 30-amp inlet also features an epoxy-potted thermal breaker that trips before wire jackets can melt, then automatically resets once temperatures drop to a safe level — a safety feature found in no other shore power system on the market. Even installation is thoughtfully designed, with color-coded clamping screws that match standard wire colors to make the process nearly foolproof.</p><h3>A Full Line of Shore Power Products</h3><p>SmartPlug's product catalog covers every link in the shore power chain. Whether you need a retrofit connector for an existing cord, a complete inlet-and-connector combo kit, or a full cordset for a new installation, SmartPlug offers solutions for 15-amp, 30-amp, and 50-amp systems. Their <a href="/11569-smartplug-marinco-shore-power-adaptors-202219">shore power adaptors</a> are especially popular among boaters who frequent diverse marinas where outlet configurations vary, ensuring a compatible, secure connection is always within reach. Beyond marine use, SmartPlug also produces RV, specialty vehicle, and dockside power products, making their system one of the most versatile shore power platforms available.</p><h3>Why Boaters and RV Owners Trust SmartPlug</h3><p>SmartPlug products are respected by marine electricians, insurance professionals, and passionate boaters alike. The ergonomic straight-in design eliminates the fumbling and torquing associated with twist-locks — a meaningful advantage when connecting in the dark, in rough weather, or for users with limited hand strength. The brand's commitment to continuous improvement is evident in ongoing design refinements driven by real-world feedback from the boating and RV community.</p><p>For anyone who stores their boat or RV at a dock or campground for extended periods, upgrading to a SmartPlug system is one of the most impactful electrical safety investments available.</p>

SmartPlug C30253

Upgrade the boat end of your shore power, while keeping the standard connection at the dockside end.

It's time for a change. These Dual Configuration Cordsets let you retrofit the boat end of your shore power system with a modern, safe and convenient SmartPlug connector and compatible SmartPlug shore power inlet (sold separately). They include a SmartPlug 30A boatside connector at one end and a standard NEMA twist-type dockside plug at the other end, so you can enjoy all the safety and security of the SmartPlug system in any marina equipped with "Old School" NEMA dockside power pedestals. 

What's in the Kit

  • SmartPlug Dual Configuration Cordset
  • Zip Storage Bag

Why the SmartPlug

Shore power delivery systems have remained virtually unchanged since they were introduced in 1938. Contrary to popular belief, the number-one cause of shore power failure and fires is not electrical shorting, but rather overheating caused by poor electrical conductivity.

These problems are built into the aging designs of common shore power technology. SmartPlug offers a better way.

The Problem with "Old School" NEMA Connectors

  • Curved pins: Electrical pins' curved shape causes minimum metal-to-metal contact, causing resistance and overheating
  • Connector body shape: The gap between the body and the inlet allows the connector to move, putting tension on the pins and clips
  • Ease of use: Difficult to find the "L"-shaped pin to twist and engage the plug, especially at night
  • Locking: No locking feature or plastic locking ring that is prone to stripping or cracking

The SmartPlug Solution

  • 30-Amp overheat protection: Oversize power pins and clips ensure efficient transfer of power even with high amperage loads
  • Electrical pins: Straight pins, not curved, with 20-times more electrical surface area; No twisting required
  • Better metal: Tinned copper wire throughout the full length of the cord set provides superior conductivity and resistance to corrosion; All external metals are 316 stainless steel; electrical pins are nickel-plated brass for maximum connectivity
  • Connector body shape: Sleeve design fits snugly within the inlet, removing all pressure and tension from pins and clips
  • Weatherproof seal: TPE Dyna-flex cord seal ensures weatherproof seal to power cord
  • Locking: Inlet cover snaps onto the sides of the inlet and the top of the connector
  • Ease of use: Unique plug body shape only goes in one way, the right way; Plug pushes straight in and locks automatically with spring-loaded side clips
  • Industry-standard hole pattern: Mounts using the same hole pattern as industry-standard layout used by Hubbel, Marinco etc.
  • Indicator Light: Cool blue LED Power indicator light on the top of the connector glows when power is on
  • Flexible: Super flexible cord that can be tightly coiled even in cold weather
