SmartPlug 30 Amp Marine Shore Power Upgrade Kit - Stainless Steel Inlet & Female Connector - B30ASSYNT

Upgrade your boat’s shore power connection with the SmartPlug B30ASSYNT, a 30 Amp boatside inlet and plug combo designed for marine applications. This premium cordset features a stainless steel connector housing and a No Thermostat (NT) design, delivering maximum durability, safety, and style for modern boats and yachts.

The stainless steel construction provides superior resistance to corrosion, UV damage, and impact, ensuring long-lasting performance even in harsh marine environments. The No Thermostat design allows for unfiltered power delivery, making it ideal for boat owners who prioritize maximum conductivity, minimal heat buildup, and overheat-free operation.

Frequently Asked Questions (FAQ)

Q: Do I need to replace my entire shore power cord to install the SmartPlug system?

A: No! The included female connector (BF30) is designed to retrofit onto the boat-side end of your existing 30A shore power cord in under 15 minutes using standard hand tools.

Q: Will this fit the existing screw hole pattern on my boat?

A: Yes, the mounting flange is specifically engineered to match the standard 3-hole or 4-hole mounting patterns used by conventional 30A twist-lock inlets.

Q: What is the difference between B30ASSY and B30ASSYNT?

A: The "NT" designation stands for "No Thermostat." Model B30ASSYNT features standard solid pins designed for maximum electrical conductivity without integrated thermal cut-off sensor wiring.

Why the B30ASSYNT is the Premium Choice

• Marine-Grade Stainless Steel: The inlet and connector cover are crafted from 316 stainless steel for a high-end look and maximum resistance to corrosion and pitting.

• Cost-Effective Pro Upgrade: Don't replace your entire 30A cable; simply retrofit the included SmartPlug female connector onto your existing cord to match the new inlet.

• Fire-Safe Technology: The patented sleeve-and-pin design ensures a cool connection, even when running high-draw appliances like air conditioners or heaters.

• Intuitive "Straight-In" Design: No more fumbling with pins or threaded rings. The connector pushes straight into the inlet and locks with dual side-locking clips.

Technical Specifications

Maintenance for Peak Performance
