Circuit Analysis
Voltage Drop Calculator
Calculate voltage drop in electrical circuits to ensure proper voltage levels at load points and NEC compliance.
Circuit Parameters
Enter circuit details to calculate voltage drop and ensure proper voltage levels at the load
One-way distance from source to load
NEC recommends maximum 3% voltage drop for branch circuits and 5% total (feeders + branch circuits). Higher voltage drops can affect equipment performance and efficiency.
