Web= 1.732 × Iwire (A) × ( L(ft) × Rwire (Ω/kft) / 1000 (ft/kft)) The line to line voltage drop V in volts (V) is equal to square root of 3 times the wire current I in amps (A) times one way wire length L in meters (m) times the wire resistance per 1000 meters R in ohms (Ω/km) divided by 1000: Vdrop (V) = √ 3 × Iwire (A) × Rwire (Ω) WebLimitations. The NEC limit for 14-gauge wire is 20 amps, which means you should never use 14-gauge wire in your 240-volt circuits, only your 120-volt circuits, or the amperage will …
