#QuestionOfTheWeek2026:
An electrician is installing a 230-volt, single-phase circuit supplying a 32-amp load.
The circuit uses #10 AWG copper THHN conductors.
Using the 2026 NEC, determine the maximum one-way circuit distance while limiting voltage drop to 6%.
🔎 Study Challenge
Don't just calculate it — find the information you need in the NEC first.
Look for:
- The circular mil area for #10 AWG
- The applicable voltage-drop information
- The appropriate voltage-drop calculation
- Any other NEC information needed to complete the calculation

A single-family dwelling qualifies for the optional calculation method under NEC 120.82. The service is rated 200 amperes, 120/240 volts, 3-wire. The following data applies:
- Floor area: 2,400 sq ft
- 2 small-appliance branch circuits + 1 laundry branch circuit
- Fastened-in-place appliances: dishwasher (1,200 W), garbage disposal (800 W), water heater (4,500 W)
- Electric range: 8,000 W nameplate
- Electric clothes dryer (not on the laundry circuit): 5,000 W nameplate
- Central air conditioning: 4,000 W nameplate
- Electric space heating: 2 separately controlled units, 10,000 W total nameplate
- No EVSE installed
Explain what method is used via the NEC 2026, and calculate what the total calculated load for this dwelling is, in volt-amperes. Show work in the comments.
