Reach extension for 20A equipment
This one-foot NEMA 5-20P to 5-20R extension cord adds reach between a wall outlet, power strip or surge protector and any standard three-prong device cord. The moulded plugs and strain relief provide a secure connection for computers, monitors, appliances and shop equipment. Rated 12 AWG, 20A at 125V, it uses a three-conductor grounded copper core inside an SJT jacket. UL Listed and CSA certified (file E210037), RoHS compliant.
Sustained-load behaviour
The 12 AWG copper conductors are rated for continuous 20A service at 125V, so the cord handles full-load operation from heavy-duty equipment without overheating. The SJT jacket is rated for indoor environments such as offices, labs and workshops; it is not intended for wet or outdoor locations. The fully grounded three-wire design maintains safety grounding throughout the extension.
12 AWG gauge decision
The wire gauge determines the maximum safe current: 18 AWG for up to 10A, 16 AWG for up to 13A, 14 AWG for up to 15A, and this 12 AWG for up to 20A equipment. Choose this cord only when the connected device and supply circuit are both rated for 20A. It will not suit applications that require an outdoor-rated jacket or a longer reach than the one-foot length.

Questions about this item
Does the 12 AWG SJT jacket run warm when powering a 20 A load all day?
The cord uses 12 AWG copper rated for 20 A at 125 V, so normal continuous operation stays within its thermal limits.
My server has a 5-20P plug — will it mate with the 5-20R outlet on this cord?
Yes, the female end is a standard NEMA 5-20R that accepts any 5-20P plug.
Can I chain this 1 ft extension to an older 14 AWG cord on the same circuit?
The 12 AWG section supports up to 20 A; the overall circuit capacity is limited by the thinnest gauge in the chain.
