EV Charging Adapter L6-20P to 14-50R

This compact adapter connects a NEMA L6-20P twist-lock outlet to a 14-50R receptacle for electric vehicle charging. It is built for Tesla UMC or other EV chargers and rated for 250 volts at 20 amps. The unit uses UL STW 12AWG stranded copper conductors and electroplated terminals. It is not intended for RV use.

Replaces Direct Plug Mismatch

The adapter solves the incompatibility when an EV charger with a 14-50 plug meets an L6-20 power source. It is worth using when the available outlet is a 20-amp twist-lock and the charger requires a 14-50 connection. The 20-amp limit means charging current must be set below that threshold. Builders needing higher amperage or a different NEMA configuration cannot use this adapter.

Sustained Load Behaviour

Heavy-duty 100% copper conductors and molded electroplated terminals resist oxidation during continuous 20-amp operation. The 12AWG stranded wire supports the maximum rated loading without overheating in normal conditions. The single-piece yellow PVC housing maintains secure contact throughout the charge session. No active cooling or monitoring features are included.

Questions about this item

What outlet and plug types does the L6-20P to 14-50R adapter connect?

The adapter has a NEMA L6-20P twist-lock male plug that fits a 250 V 20 A outlet and a NEMA 14-50R female receptacle that accepts an EV charger plug.

How do I install the adapter and what setting must I change on the charger?

Plug the L6-20P end into the twist-lock outlet, then insert the EV charger's 14-50 plug into the adapter; set the charger to draw 20 A or less.

What should I check periodically on the adapter's cable and contacts?

Inspect the yellow PVC jacket for cuts or heat damage and verify the electroplated copper terminals remain clean and free of oxidation.
