The Electrician
Pick a lab below. Every calculator obeys real NEC rules — ampacity, derating, continuous-load limits, and voltage-drop targets.
Ohm's Law
Power wheel + NEC 80% continuous-load check.
Ampacity Chart
NEC 310.16 wire ampacity with ambient + fill derating.
Panel Capacity
Demand vs service — 125% continuous-load rule.
Voltage Drop
V = 2·I·R·L · 3% branch / 5% total.
Conduit Bend
Trig multipliers for offset bends.
