Kanayu 15 ft 30A Generator Adapter Cord with Pre-Drilled L14-30 Inlet Box — 10 AWG STW, Weather-Resistant

Kanayu's 15-foot, 30-amp generator adapter cable and pre-drilled inlet box convert a TT-30P generator outlet to an L14-30R lock-style inlet, giving you a safe, ETL-listed connection to a manual transfer switch and up to 3,750 watts of power.

When a portable generator only offers a TT-30 (three-prong RV) outlet but your house transfer switch or inlet requires an L14-30 (four-prong, 30A, 250V) connector, this kit bridges the gap without permanent rewiring. The package includes a 15-foot heavy-duty STW 10 AWG adapter cord (TT-30P to L14-30R) and a pre-drilled, weather-resistant L14-30P inlet box rated for 30 amps. Each component is designed for outdoor use, visible identification, and straightforward installation so you can position the generator away from your home while maintaining safe, code-conscious connections.

How does this adapter cable ensure safe generator-to-house connections?

The cord uses 10 AWG copper conductors with STW-rated insulation for outdoor durability and a molded TT-30P plug plus a locking L14-30R female end to prevent accidental disconnection. Materials include flame-retardant and UV-resistant jacketing, and the cord supports up to 30A, 250V (maximum 3,750 watts).

• 3-conductor 10 AWG copper for reliable current capacity
• Molded TT-30P plug and locking L14-30R receptacle for secure fit
• STW jacket: weather, UV, and flame resistant for outdoor use
• Rated for 30A/250V, up to 3,750 watts continuous load

What features make the inlet box installation-friendly?

The included inlet box arrives pre-drilled and pre-configured for an L14-30P lock-style plug, which cuts installation time and reduces the need for specialty tools. Its spacious wiring cavity and anti-rust coating simplify neat connections to a manual transfer switch or house wiring, while ETL listing signals independent safety evaluation.

• Pre-drilled faceplate for quick mounting and wiring
• L14-30P lock mode inlet ready for the adapter cord
• Generous wiring area for tidy conductor routing
• Anti-rust finish and ETL listing for durability and compliance

Can I use this kit outdoors for RVs, tailgates, or during outages?

Yes — the cable and inlet box are built for outdoor placement so you can keep the generator distant from living spaces to reduce exhaust and noise. The bright yellow jacket improves visibility at night or in crowded areas, reducing trip hazards when running power to RVs, events, or backup systems.

• Bright yellow jacket for easy locating in low light
• Designed for generator-to-house and generator-to-RV setups
• Keeps generator position flexible for noise and exhaust control
• Suitable for emergency backup, camping, tailgating, and events

How do I match this adapter to my generator and transfer switch?

Confirm your generator has a TT-30 (three-prong) outlet and your inlet or transfer switch accepts an L14-30 (four-prong locking) connection. This kit specifically adapts TT-30P generators to L14-30R transfer inlets; it does not change voltage or bypass transfer-switch safety procedures.

• Works when generator outlet = TT-30 and inlet = L14-30
• Does not alter generator voltage or safety interlocks
• Use with a manual transfer switch or inlet box only
• Confirm 30A/250V compatibility before use

Who is this for? Homeowners and RV owners who need a dependable, visible, and code-aware way to connect a TT-30-equipped generator to an L14-30 inlet or manual transfer switch will find this Kanayu kit useful. Electricians, event operators, and anyone wanting to position a generator safely away from structures will appreciate the 15-foot reach, durable STW construction, and pre-drilled inlet box that speeds installation without sacrificing safety or visibility.
