Uses a round-trip conductor path for single-phase portable loads.
Enter the real running current, not only the breaker size.
Distance from receptacle to load in feet.
Tight targets help motors, compressors, pumps, and sensitive electronics.
No common cord size in this range passes both screens.
Try a shorter run, lower load, or hardwired circuit.
Heavy portable loads and very long runs often need 8 AWG or larger temporary cable, a shorter setup, or a permanent branch circuit closer to the equipment.
The calculator checks common copper cord sizes from 16 AWG through 8 AWG.
Each option must pass both the entered current and the selected voltage-drop target.
Voltage drop uses round-trip conductor length, which is why a 100-foot cord is calculated as 200 feet of conductor path.
Motors, compressors, pumps, and pressure washers usually benefit from a 2% to 3% drop target.
Portable heaters and other long-running loads should use real running current, not a rounded estimate.
If plugs feel warm or the tool starts sluggishly, shorten the run or move up another gauge.
This is a planning tool, not a substitute for the cord manufacturer rating or the equipment instructions.
Do not use extension cords as permanent wiring through walls, ceilings, floors, or concealed spaces.
Large generators, welders, and specialty flexible cable systems may need cord types and conductor sizes beyond this simplified range.
Voltage Drop Calculator
Run a full branch-circuit voltage-drop check after you choose the cord or feeder size.
Ampacity Calculator
Compare portable-cord planning against installed-conductor ampacity checks.
Conduit Fill Calculator
Use this when the temporary setup becomes permanent wiring in raceway.
Cable Size Calculator
Move from extension-cord planning to full cable sizing for fixed installations.
Wire Resistance Calculator
Review conductor resistance directly if you want to inspect the loss math.
Wire Weight Calculator
Estimate reel weight and handling load for long heavy-duty cords or cable runs.
