Shore power plug solutions for RVs can be a bit of a challenge, but understanding the basics can make a big difference.
There are two main types of shore power plugs: 30-amp and 50-amp. The 30-amp plug is designed for smaller RVs and appliances, while the 50-amp plug is better suited for larger RVs and heavy-duty appliances.
The type of shore power plug you need depends on your RV's electrical system and the size of your appliances. For example, if you have a smaller RV with a 30-amp electrical system, a 30-amp shore power plug is the way to go.
A 50-amp shore power plug, on the other hand, can handle more power and is a good option for RVs with larger appliances like air conditioners and microwaves.
Shore Power Plug Types
Shore power plug types vary depending on the country and region.
The most common type is the Type A plug, which is used in the United States and has two parallel flat prongs.
Type B plugs, also used in the US, have the same two parallel flat prongs as Type A but with a grounding pin.

Connect to Shore Power
Connecting to shore power is a vital part of boating, ensuring your electrical devices stay powered while on the water.
Marinco marine-grade plugs and connectors provide superior strain relief, effective dust seals, and a durable design for safe and reliable connections.

A shore power connection is the "life line" from the shore to the boat, powering technical equipment when not cruising. It's a critical component that needs to be reliable.
The WhisperPower battery charger or inverter/charger combi recharges and maintains the voltage for service, starter, and bow thruster batteries, keeping them in perfect condition throughout the year.
Shore power entails plugging your boat into a "shoreside" power source, usually a pedestal, on the dock to transfer AC power to your boat.
Overton's carries a wide selection of shore power cords, inlets, plug holders, and more to meet all your power needs.
Technical Guidance
When choosing a shore power plug, consider the type of electrical system on your boat. A 30-amp shore power plug is suitable for most small boats with a single cabin and limited electrical systems.
The most common types of shore power plugs are 30-amp and 50-amp. The 50-amp plug can handle more power-hungry systems, but it requires a dedicated 240-volt circuit on shore.

A 50-amp shore power plug has a higher amperage rating than a 30-amp plug, allowing for more power to be drawn from the shore power source. This makes it ideal for larger boats or those with multiple air conditioning units.
To ensure safe and efficient operation, it's essential to match the shore power plug to your boat's electrical system. Consult your boat's electrical system documentation or consult with a marine electrician if unsure.
The National Electric Code (NEC) requires that shore power plugs be rated for the maximum ampacity of the circuit they are connected to. This ensures that the plug can handle the electrical load without overheating or causing a fire.

Shore power is typically 110-volt, similar to household power, allowing you to easily connect and use your boat's appliances while docked. However, some marinas may offer 220-volt shore power, so it's always best to check with the dock before plugging in.
What is shore power charging?
Shore power charging converts AC power from a campsite's electrical hookups into DC power to charge your RV's batteries, keeping them topped up and ready to go
