Jerry what percentage of house do you find with more that 5% VD?
I am going to guess it is a very large number. ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif)
How do you sleep at night with all that is wrong in peoples homes?
Just kidding with you Jerry, not everything is a big deal. (At least in my not so humble opinion
Report it, don't report it, the test means little as the it all depends on the how heavy the load is on the circuit.
You test with 12 amps of load on a 15 amp circuit, but in use a single duplex outlet almost never gets loaded that heavily.
Now if this is new construction and the contract for the EC had a specification that voltage drop could not exceed 5% with 80% loading at the furthest point on the circuit you certainly have something to report.
This is a typical specification I have to meet at the jobs we do, many times this means 10 AWG for 20 amp circuits.
FWIW most UL standards require utilization equipment to operate + or - 10%
However that is the total variation, the 5% VD in the structure and
any variation by the power company.
