Indoor Power Extension for 20 Amp Circuits

This Cable Leader PW143-1210 cord extends the reach of equipment using a NEMA 5-20P plug by ten feet. The 12 AWG SJT cable carries 20 amps at 125 volts for computers, monitors, appliances and shop tools. Molded 5-20P to 5-20R connectors provide a fully grounded three-wire path. UL and CSA certifications confirm compliance for indoor environments.

Verify Your Outlet and Device Compatibility

Confirm that both the wall receptacle and the equipment plug match the NEMA 5-20 configuration with its distinctive T-blade neutral slot. The cord is rated for indoor use only and must not be routed through wet or outdoor locations. Ensure the connected load does not exceed the 20 amp, 125 volt rating marked on the cable jacket.

Durable Construction for Daily Indoor Use

Heat-resistant PVC sheathing and a flame-retardant coating protect the copper conductors during routine operation. Molded plugs incorporate strain relief to resist damage from repeated insertion or cable tension. The ten-foot length allows flexible placement of workstations or bench equipment without permanent rewiring.
