Voltage Drop from Meter

Voltage Drop from Meter

Voltage Drop from Meter

(OP)
What is considered the average or normal voltage drop from my meter to my breaker panel?  I understand the ANSI standard range for service voltage at meter is 114-126V and 110V minimum at the receptacles, but what is % voltage drop should one expect at the main breaker panel?  thanks!

RE: Voltage Drop from Meter

Depends on the length and size of the feeder and the load that's present...  Could be up to two to three percent, or down to darn near zero.  Common practice was to design wiring to insure no more than five percent to the end point of use.

You can compute -- look up AC resistance for the size wire in your feeder, and do the V = I * R thing.

Good on ya,

Goober Dave
