Extends standard 3-prong power cords

This 25 ft extension cord adds reach between a wall outlet, power strip or surge protector and any device that uses a NEMA 5-15 plug. It is built for indoor use in offices, labs, workshops and homes where the existing cord falls short. The male 5-15P plug connects to the supply side and the female 5-15R receptacle accepts the equipment cord. Rated 13A at 125V, it suits computers, monitors, appliances and shop equipment.

Plug in and route the cord indoors

Installation is straightforward: insert the male plug into the power source and plug the device into the female end. The molded plugs and strain relief reduce the chance of loose connections. The SJT jacket is rated for indoor environments only; using it in wet or outdoor locations is unsafe and not supported. A common mistake is selecting a gauge that is too light for the load, so verify the device draw before use.

13A capacity for typical desktop loads

The 16 AWG copper conductors handle up to 13A, covering most desktop computers, monitors and similar office gear. Heavier loads such as servers, PDUs or equipment drawing above 13A will exceed the rating; 14 AWG supports up to 15A and 12 AWG up to 20A for those cases. The cord is UL Listed and CSA certified (file E210037) and RoHS compliant. Buyers who need outdoor-rated cable or higher amperage should choose a different gauge or jacket type.

Questions about this item

How can I confirm the 16 AWG cord is working correctly after plugging it into a 125 V outlet?

The molded 5-15P plug and 5-15R receptacle should seat firmly; the connected device powers on without the cord or plugs becoming warm during normal 13 A use.

What comes in the box and is any extra hardware required?

The package contains only the 25 ft black SJT extension cord with molded 3-prong plug and receptacle; no additional hardware is needed for indoor connection to a standard outlet or power strip.

Which gauge should I choose between 16 AWG and the other listed options?

Select 16 AWG for computers and appliances drawing up to 13 A; use 18 AWG for lighter loads up to 10 A, 14 AWG for servers up to 15 A, or 12 AWG for heavy 20 A equipment.
