Nilight 30A RV Generator Adapter L14-30P to TT-30R — 14.6in 10 AWG, 3750W Durable Outdoor Cord

Nilight's 30 Amp L14-30P to TT-30R RV generator adapter cord converts a 4-prong 30A generator outlet to a 3-prong RV inlet, delivering up to 125V and 3750W for temporary campsite power.

This compact adapter cable bridges a 30‑amp four‑prong generator outlet (NEMA L14‑30P) to a 30‑amp three‑prong RV receptacle (NEMA TT‑30R). Built with three 10 AWG stranded copper conductors and a flame‑retardant PVC jacket, it’s designed for reliable short-term power hookups to run appliances like refrigerators, AC units, microwaves and other typical RV loads while camping or during portable generator use.

How does this adapter handle generator-to-RV connections?

The adapter turns a locking 4‑prong generator plug into a 3‑prong RV inlet, making it simple to connect older or differently configured RVs to modern generator outlets. It’s intended for temporary supply only and does not change voltage or regulate current.

• Connector types: NEMA L14‑30P (male, 4‑prong) to NEMA TT‑30R (female, 3‑prong)
• Rated output: 125 volts, up to 3750 watts (30 amps)
• Length: 14.6 inches—compact for storage and quick hookups
• Note: Not a voltage/current regulator—use only as an adapter

Is the cord durable enough for outdoor use?

Yes — the cable uses stranded 10 AWG pure copper conductors inside a rugged STW-style thermoplastic jacket that resists heat, flame and weather exposure. That construction keeps the adapter flexible for routing while protecting it from common campsite wear and environmental stressors.

• 100% pure stranded copper for better conductivity and flexibility
• Heavy-duty flame-retardant PVC outer jacket for abrasion and weather resistance
• Designed to withstand wind, rain, snow, dirt and rough surfaces
• Pressure-proof twist-lock male plug ensures a secure connection

What appliances and loads can I safely power with this adapter?

The adapter supplies a standard 30‑amp RV circuit, so it can power most RV household appliances within the 3750W limit. Always confirm your combined appliance wattage does not exceed the generator and adapter ratings and follow generator manufacturer guidelines.

• Suitable for refrigerators, air conditioners, microwaves and small kitchen appliances
• Not intended for continuous heavy industrial loads or to exceed 30 amps
• Use load calculators or appliance nameplate ratings to verify compatibility

How do I check compatibility before buying?

Confirm your generator outlet is a NEMA L14‑30 (four‑prong locking) and your RV inlet is a NEMA TT‑30 (three‑prong 30A). This product is a 4‑prong male to 3‑prong female adapter—double‑check plug types to avoid mismatched hardware.

• Measure or inspect plugs: L14‑30P (twist-lock 4 prong) to TT‑30R (3 prong RV)
• Verify required amperage: both sides are rated at 30 amps
• Remember: adapter does not alter voltage or phase—match system specs

Who this is for: RV owners, weekend campers and anyone using a portable generator who needs a compact, reliable way to connect a 30A RV inlet to a 30A generator outlet. This adapter is ideal for temporary campsite hookups, emergency power situations and travelers who want a durable, flexible cord that stores easily in an RV compartment or generator bag. It’s not a permanent electrical solution, and should be used according to generator and RV electrical safety guidelines.
