Frequently Asked Questions
Voltage drop is the reduction in voltage in an electrical circuit between the source and load due to wire resistance.
Typically, a voltage drop of 3% or less is acceptable for branch circuits, and 5% for total system.
Yes, longer wires result in higher voltage drop because resistance increases with length.
