Cerrowire’s Voltage Drop, Conduit Fill and Amperage Calculator is a must have for all electrical professionals. The most commonly needed tools are presented in one easy-to-use calculator.

This app consists of three separate calculators that calculate the minimum wire size needed for a run of an inputted length to stay within a recommended voltage drop percentage, the fill % based on the cables and conduit used, and the amperage of a cable (per the NEC Table 310-15(B)(16)) based on wire size, wire type and temperature.

Features:

• Single app for multiple tools
• Easy-to-use interface with tabs for each calculator
• Calculates voltage drop for 120 Volts, 208 Volts, 120/208 Volts (4 Wire), 240 Volts, 277 Volts, 480 Volts, or 277/480 Volts (4 wire) voltages.
• Works for either copper or aluminum conductors.
• Works for THHN/THWN, XHHW, or USE conductor types.
• Conduit fill calculator works for EMT, ENT, FMC, IMC, PVC, Type EB PVC, LFNC-A, LFNC-B, LFMC, and RMC conduit types.
• Conduit fill calculator works for 14 AWG through 750 MCM conductor sizes.
• Amperage calculator works for 14 AWG through 1000 MCM conductor sizes.
