Drop'N Volts

Drop N Volts is a powerful, field-ready voltage drop and conductor sizing calculator built for electricians. Enter your load, distance, material, and phase (single or three-phase), and instantly get the minimum conductor size required.

Go beyond basic calculations by adding multiple conductors to your run and ensuring compliance with NEC conduit fill requirements. Select conductor insulation types and conduit materials to match real-world installations.

Designed for accuracy and efficiency, Drop N Volts helps you plan complete runs—not just single circuits. Once finished, easily email detailed results including all key inputs and calculations for documentation or review.
