Conable's 1-foot L14-30P to 14-50R adapter cord converts a 30A twist-lock generator outlet into a secure 50A RV/EV inlet for safe 125/250V, 3750W power connections.

This compact, heavy-duty adapter lets you connect 50-amp RVs or Level 2 EV chargers to a 30-amp generator output using a NEMA L14-30P twist-lock male and a NEMA 14-50R female receptacle. Built with 10/4 AWG pure copper conductors and an STW-rated PVC jacket, the cable is designed for outdoor use, high heat tolerance, and reliable current transfer. It is ETL listed and intended for temporary generator-to-vehicle or charger hookups where equipment ratings and local electrical codes permit.

How does this adapter keep a secure connection during generator use?

The adapter uses a NEMA L14-30P twist-lock male plug at the generator end so the connection resists vibration and accidental pull-out. The twist-lock action creates a mechanical hold that stays engaged under moderate movement. The 14-50R female receptacle includes an ergonomic handle to make mating and unmating easier without stressing the cord.

  • Twist-lock L14-30P prevents accidental disconnection
  • Ergonomic handle on 14-50R for safer plug removal
  • 10/4 AWG pure copper for stable electrical contact

Is this cable safe for outdoor and high-heat environments?

Yes — the jacket is STW-rated PVC with flame retardant, heat- and UV-resistant properties designed for outdoor jobsite conditions. The heavy-duty construction reduces abrasion and weather damage during short-term use. Always confirm your generator and vehicle/charger ratings before connecting and avoid permanent installation situations where a permanent-rated cable is required.

  • STW jacket resists heat, sunlight, and wear
  • Flame-retardant PVC helps reduce fire risk from surface ignition
  • 10AWG copper conductors for lower resistive heating

Can I use this adapter to charge electric vehicles like Tesla models?

The adapter provides a 125/250V, up to 3750W connection suitable for Level 2 charging equipment that accepts a 14-50 inlet. It can be used with EVSEs compatible with 14-50 inlets (Tesla Mobile Connector and many aftermarket EVSEs), but charging speed will be limited by generator capacity and the adapter’s 30A source. Verify your EVSE, vehicle acceptance, and local regulations before connecting.

  • Works with EVSEs that accept NEMA 14-50 inlets
  • Charging rate limited by generator output and adapter rating
  • Useful for temporary or emergency charging when permitted

What power and certification details should I check before using this adapter?

This cord is rated for 125/250V and up to 3750 watts with 10/4 AWG copper conductors and carries ETL listing for safety standards compliance. It is intended for temporary generator-to-equipment use only; do not rewire or modify the connectors. Always match generator output, breaker protection, and appliance/EVSE requirements to prevent overloads.

  • 125/250V, 3750W maximum load
  • 10AWG pure copper, four-conductor cable construction
  • ETL listed — follow local electrical codes and manufacturer instructions

Who is this adapter for? If you need a short, heavy-duty cable to adapt a generator's L14-30 twist-lock outlet to a 14-50 inlet for an RV or compatible EVSE, this Conable 1-foot adapter is designed for that purpose. It's aimed at RV owners, mobile EV charging setups, contractors, and anyone who needs a portable, secure temporary connection between a 30A generator source and 50A equipment. It is not a substitute for permanently installed wiring or panels; consult a licensed electrician for fixed installations and always adhere to equipment ratings and local code.
