Electrical โ FAQ
Does Greenlee actually make power extension cords?
No. Greenlee manufactures drill extensions and electrical tools, not power cords. The search results mix Greenlee drill accessories with other brands' power cords. Electricians should buy Greenlee for drilling needs and trusted brands like Klein or Southwire for power delivery.
What's the difference between a drill extension and a power extension cord?
Drill extensions are flexible shafts that attach to drill bits, allowing you to bore holes around corners and through tight spaces. Power extension cords deliver electricity from outlets to tools. They serve completely different purposes on a job site.
What gauge extension cord do I need for 15-amp power tools?
Use 12 AWG for runs up to 50 feet. For 100-foot runs, step up to 10 AWG to prevent voltage drop and tool overheating. Sixteen AWG cords are only suitable for light-duty tools under 10 amps and should never be used for table saws or rotary hammers.
Are lighted ends on extension cords worth the extra cost?
Absolutely. The LED indicator immediately shows if the cord is live, preventing accidental cuts and troubleshooting dead outlets. On job sites with multiple cords, this feature saves time and prevents injuries. Klein and Southwire both offer this feature standard.
Can I use an indoor extension cord outdoors?
Never. Indoor cords lack UV-resistant jackets and weather sealing. They crack within weeks of sun exposure, creating shock hazards. Always use cords marked 'SJTW' or 'SJEOW' for outdoor electrical work, and ensure connections stay dry.
How do I maintain my extension cords and drill extensions?
Coil cords properly without kinks, store indoors, and inspect for cuts before each use. Clean drill extensions with a dry cloth after use; never oil them. Replace any cord showing copper exposure or any flex shaft that binds or wobbles.
