NEMA 6-20 Extension Cord for 20 A Equipment

This NEMA 6-20 extension cord connects a 6-20P male plug to a 6-20R female receptacle that also accepts 6-15R plugs. It uses 12 AWG copper conductors rated for 20 amps at 250 volts, delivering up to 5000 watts. The 50-foot SJTW jacket suits indoor or outdoor power runs for high-draw devices.

Replaces Shorter or Undersized Leads

A standard 15-amp cord cannot sustain the 20-amp continuous load this cable handles without voltage drop or overheating. Upgrading is worthwhile when equipment such as welders, EV chargers or server PDUs draws near the 20-amp limit and the existing lead is shorter than 50 feet or uses thinner gauge wire.

Integrates with 250 V Circuits

The cord requires a NEMA 6-20 outlet on a dedicated 20-amp branch circuit protected by a matching breaker. It frees equipment placement by extending reach up to 50 feet without adding intermediate connections. Builders needing a different plug configuration or a lower ampacity rating should select a cord specified for that service.

Questions about this item

What plug and receptacle types does the 50-foot cord use?

The cord has a NEMA 6-20P male plug on one end and a NEMA 6-20R female receptacle that also accepts 6-15R plugs on the other.

How do I connect the cord safely, and what step is often missed?

Ensure the circuit is off, then insert the 6-20P plug fully into the matching outlet and seat the device plug firmly into the 6-20R receptacle; the step often missed is confirming both connections are fully latched before restoring power.

When should the cord be inspected or replaced?

Inspect the SJTW jacket and 12 AWG copper conductors before each use; replace the cord if the insulation shows cuts, the blades are bent, or the receptacle grips feel loose.
