Extending Power Reach Indoors

This 100 ft power extension cord adds reach between a standard wall outlet, power strip or surge protector and any 3-prong device cord. The NEMA 5-15P plug and 5-15R outlet are fully grounded with a true 3-wire design and molded strain relief. It is built for indoor use in offices, labs, workshops and homes with a SJTW jacket. UL Listed and CSA certified file E210037 confirms safety compliance.

Thermals Noise And Power Draw

The cord uses 12 AWG copper conductors rated for 15 A at 125 V, supporting continuous loads up to 15 A without overheating. The SJTW jacket remains flexible at room temperature and does not generate audible noise during operation. Power loss over the 100 ft length stays within normal limits for 12 AWG wire at rated current. No active cooling or moving parts are present, so thermal and acoustic output is negligible.

Build Quality And Daily Use

Heavy duty 12 AWG 3-conductor grounded copper with a durable SJTW jacket resists abrasion and kinking during routine handling. Molded plugs with integrated strain relief protect the internal connections when the cord is plugged and unplugged repeatedly. The black finish suits professional and home environments. Indoor rating means it should not be used in wet or outdoor locations. RoHS compliant materials meet restricted substance standards.

Questions about this item

How do I install the 100 ft 12 AWG cord without creating a trip hazard?

Route the SJTW-jacketed cable along baseboards or cable trays; the step people miss is leaving slack at both moulded plugs so strain relief is not defeated.

What maintenance or replacement will the 12 AWG extension need later?

Inspect the 3-prong 5-15P and 5-15R ends for cracked insulation or loose blades; replace the cord if the grounded copper conductors show any damage.

What limit appears first when the cord runs at 15 A continuously?

The 125 V, 15 A rating of the NEMA 5-15 connectors is reached before the 12 AWG copper itself, so do not exceed 15 A sustained load.
