ELEGRP 30 Amp Generator Adapter Cord

ELEGRP's 30 Amp generator adapter converts a NEMA L5-30P generator outlet to a TT-30R RV receptacle, letting you safely run a travel trailer or camper from a compatible generator.

When you need reliable temporary shore power for an RV or travel trailer, this compact dogbone adapter provides a secure, high-capacity link between generator and camper. Built with 10-gauge copper conductors, a twist-lock plug, and a flexible 12-inch body, it balances durability with ease of use so power equipment remains protected and accessible during trips or outages.

How does this adapter keep the connection secure while the generator runs?

The adapter uses a NEMA L5-30P twist-lock male plug that locks into the generator outlet with a quarter-turn, preventing accidental unplugging from vibration or movement. The molded housing fits tightly and the short, flexible dogbone relieves stress at both ends.

• Twist-lock L5-30P ensures a frictionless locked connection
• Molded strain-relief reduces wire fatigue at the plug
• 12-inch flexible length prevents rigid pull on outlets

Will it supply enough power for my RV appliances?

This adapter is rated for 30 amps at 125 volts, with a maximum capacity of 3,750 watts, suitable for many RV circuits and appliances when load-managed. It’s intended to provide temporary power for essential systems rather than serve as permanent campground wiring.

• 30 A / 125 V rating supports standard RV loads
• 3,750 W maximum combined power under correct generator sizing
• Use power management to avoid overloading single-generator output

What materials and construction features make it durable outdoors?

The cord is built from 10/3 AWG copper conductors inside an STW-rated jacket for abrasion and sunlight resistance. Molded ends and a robust handle on the RV connector improve longevity and make repeated connections easier to grip in the field.

• 10-gauge copper for low resistance and heat tolerance
• STW jacket protects against moisture, wear, and UV exposure
• Ergonomic female handle for safe, controlled disconnects

How do I know this adapter is compatible with my generator and RV?

Compatibility depends on the generator’s outlet and the RV inlet. This adapter specifically fits a generator with a NEMA L5-30 (3-prong twist-lock) outlet and an RV with a TT-30 (NEMA TT-30R) 30 amp inlet. Always confirm both outlet types before purchasing.

• Generator must have NEMA L5-30 receptacle (30A twist-lock)
• RV must accept a NEMA TT-30P (30A RV) plug
• Not a substitute for permanent shore power panels or mismatched voltages

Who is this for: The ELEGRP 30 Amp generator-to-RV adapter is made for RV owners, campers, and technicians who need a short, robust connector to run travel trailers or small motorhomes from a compatible portable generator. It’s ideal for weekend campers, seasonal travelers, emergency backup setups, and anyone who requires a secure, weather-resistant adapter that minimizes strain on generator outlets. Note: verify your generator outlet type and observe safe load management when powering multiple appliances.
