FAQ

This adapter is designed for use with any standard or inverter-rated generator equipped with a 30-amp RV power receptacle (TT-30). It is commonly used for RVs, travel trailers, campers, and portable power setups requiring a transition from a 30-amp source to standard 15-amp household outlets.
This cord converts a 30-amp TT-30P plug into one or more standard 120V NEMA 5-15R outlets. It allows you to power household appliances, tools, or electronics from a generator or RV power pedestal that only provides a 30-amp RV connection.
These adapters typically utilize heavy-duty 10-gauge (10AWG) 3-conductor wire, often featuring STW or SOOW jacketing. This construction is rated for 30 amps at 125 volts, ensuring the cable can handle the load safely while remaining flexible and durable for outdoor use.
While this adapter allows you to plug in standard 15-amp devices, the total power draw across all connected outlets must not exceed the capacity of the circuit. Always be mindful of the total wattage of your connected devices to avoid tripping the generator's breaker or overloading the adapter.
This cord is designed as a temporary power distribution solution. While it is built with durable, weather-resistant materials like STW or SOOW cable, it should not be used as a permanent replacement for fixed electrical wiring or installed in a way that exposes the connections to standing water or extreme environmental conditions.
