  • Connector Typetype
  • Connects 50A outlet to 20A plug for welders and EV charging
  • 12AWG STW cord stays flexible in cold weather
  • Bright orange jacket improves visibility in dim or cluttered spaces
  • UL listed for 250V safety compliance
  • 5 ft length reduces cable clutter at the work site

Intended use

This NEMA 6-50P to 6-20R adapter connects a 50 A 250 V supply to equipment fitted with a 6-20 plug. It serves welders, plasma cutters and EV owners who need a level 2 charge from an existing 6-50 outlet. The 1.5 ft length suits fixed or semi-fixed installations. It is not for 120 V circuits or devices that require a higher amperage than 20 A.

Build and connectors

The cord uses STW 12 AWG three-conductor cable with a rubber jacket that stays flexible in cold weather. An orange finish improves visibility in dim or cluttered work areas. The assembly carries UL certification, confirming compliance with relevant safety standards. Moisture resistance allows outdoor use, though prolonged sunlight may discolour the jacket.

Thermals and power

Rated for 20 A continuous at 250 V, the adapter handles typical welder and EV charging loads without overheating. The 12 AWG conductors and UL-listed construction keep temperature rise within safe limits during normal operation. No active cooling is required and the passive design adds no audible noise. Power draw depends entirely on the connected equipment.

Questions about this item

What current does the NEMA 6-50P to 6-20R adapter support in practice?

The adapter is rated for 50 A on the plug side and 20 A on the receptacle side at 250 V, so the connection is limited by the 20 A receptacle rating.

What physical clearance does the 1.5 ft STW 12 AWG cord need to fit?

The cord is 1.5 ft long with a 12 AWG three-conductor STW jacket; allow enough slack for the plug and receptacle bodies plus the short cable run.

How is the adapter installed, and what step do users often miss?

Plug the NEMA 6-50P end into the 50 A outlet, then insert the 6-20 plug into the receptacle; verify the circuit breaker is rated for 20 A or less so the receptacle is protected.
