What Is The Max Voltage Drop Allowed at David Greenfield blog

What Is The Max Voltage Drop Allowed. Find nearest lower voltage drop value in tables, in correct column for type of conductor, conduit and power factor. 8.4.1.2 requires branch circuit conductors to be sized for a maximum voltage drop of 3% at design load. This nec article limits the voltage drop on any branch circuit serving sensitive electronic equipment to 1.5% of the applied voltage. Divide voltage drop by ii (amperes x circuit feet). The maximum total voltage drop for a combination of both branch circuit and feeder should not exceed 5%. Alternatively, the maximum combined voltage drops on the feeder and branch circuits going to sensitive electronic equipment should be limited to 2.5%. Typical values for lv installations are given below in figure g27. The total conductor voltage drop (feeder and branch circuit) shouldn't exceed 120v×0.05=6v. The maximum conductor voltage drop recommended for both the feeder and branch circuit is 5% of the voltage source (120v). Determine maximum desired i voltage drop, in volts. Read conductor size for that value. Section 647.4(d) limits the voltage drop on any branch circuit serving sensitive electronic equipment to 1.5% of the applied voltage. While the nec does not have a general mandatory voltage drop rule, some of the energy code that are being adopted do have.
