The SmartPlug 50 Amp Connector & Non-Metallic Inlet (B50ASSYPW) delivers a safer, more reliable shore power connection for boats and yachts requiring high-amperage service. Designed with SmartPlug’s patented solid pin technology, this system increases electrical contact and significantly reduces heat buildup compared to traditional twist-lock shore power connections.
This kit includes a 50 Amp SmartPlug connector and a non-metallic white inlet, providing a clean, corrosion-resistant installation that stands up to harsh marine environments. The inlet’s non-metallic housing eliminates corrosion issues common with metal inlets, while the SmartPlug connector locks securely in place to prevent accidental disconnects and power loss at the dock.
Ideal for boat owners upgrading from legacy shore power systems, the SmartPlug B50ASSYPW enhances electrical safety, durability, and peace of mind in both freshwater and saltwater applications.
High-Contact Safety: Patented pin-and-sleeve design eliminates electrical arcing and the risk of melted inlets.
Complete Retrofit Kit: Comes with everything you need to upgrade both the boat/RV side and your current 50A power cable.
Weatherproof Protection: The white inlet is made from high-impact, UV-resistant resin and features triple silicone seals to lock out moisture and salt.
Easy Installation: The inlet fits the industry-standard 4-hole mounting pattern, making it a "drop-in" replacement for most Marinco, Furrion, or Park Power inlets.
Secure Locking System: Heavy-duty side clips and a locking lid prevent the cord from being accidentally pulled out or vibrating loose.

To ensure a lifetime of safe power, follow these simple steps:
Fresh Water Rinse: Regularly rinse the inlet and connector with fresh water to remove salt and dirt.
Seal Check: Periodically inspect the silicone seals for wear to maintain a watertight connection.
Store Dry: Keep the cable connector protected from the elements when not in use.
Don't throw away a perfectly good 50A cord just because the ends are outdated. The B50ASSYPW allows you to cut off your old twist-lock end and install the SmartPlug connector in minutes, giving you a professional-grade, fire-safe system for a fraction of the cost of a new cordset.
