NEMA 6-20 Power Extension

This three-foot cord extends a NEMA 6-20 outlet to reach equipment that sits further from the wall. It carries 250 V at up to 20 A for a 5000 W maximum load, making it suitable for high-draw devices such as welders, compressors or server PDUs. The 12 AWG SJTW cable is rated for heavy-duty indoor use.

Electroplated Copper Terminals

Molded connectors use electroplated copper terminals that resist surface oxidation over repeated mating cycles. The 100 % copper conductors inside the jacket maintain low resistance and consistent current delivery. These materials reduce the chance of hot spots during sustained 20 A operation.

T-Blade Female Accepts 6-15 Plugs

The receptacle accepts both NEMA 6-20 and NEMA 6-15 plugs, giving flexibility when connecting equipment with either blade pattern. The three-foot length adds reach without excessive slack in tight equipment bays. Builders needing longer runs or outdoor-rated jackets will need a different cord.

Questions about this item

Will the electroplated copper terminals need periodic cleaning to prevent oxidation?

The terminals are moulded with electroplated copper specifically to avoid surface oxidation, so routine cleaning is not required.

What is the maximum continuous current the 12 AWG SJTW cable can carry before it becomes the limiting factor?

The 12 AWG SJTW conductors are rated for a maximum of 20 A, matching the NEMA 6-20 plug and receptacle rating.

Does the cord generate noticeable heat when running at 5000 W continuously?

The 100 % copper, 12 AWG SJTW construction is designed for the full 20 A, 250 V load, keeping temperature rise within normal limits for this wire gauge.
