Cable Leader 3ft NEMA 5-20P to 5-20R Heavy Duty Power Extension Cord, 12 AWG SJT 20A/125V, Black - 3 Prong 20A Extension Cable for Shop, Server & Equipment, UL Listed

The Cable Leader 3 ft NEMA 5-20P to 5-20R power extension cord adds 20A reach to high-draw equipment. The 5-20P plug goes into a 20A wall outlet, power strip or PDU; the 5-20R T-slot outlet accepts your existing 15A or 20A power cord - so you can place shop tools, servers and equipment exactly where you need them.

Built with heavy-duty 12 AWG, 3-conductor grounded copper and an SJT jacket, it is rated 20A / 125V (300V cable rating). Fully molded plugs with strain relief and a true 3-wire grounded design make it safe and durable for demanding indoor use.

Indoor duty: the SJT jacket is intended for indoor environments. For wet or outdoor locations, choose an outdoor-rated (SJTW) cord instead.

Choosing the right gauge: 18 AWG handles up to 10A for light electronics; 16 AWG up to 13A for computers and appliances; 14 AWG up to 15A for servers, PDUs and higher-draw equipment; 12 AWG up to 20A for heavy-duty and 20A circuits.
