I just had a conversation with a friend doing housing inspections. He, on occasion, uses an Ideal circuit tester to measure voltage drop for specific clients. Recently, he found a rather large, new, 600K house with an office/den that had outlets consistantly showing 15% voltage drop when tested.
The tester will be calculating the drop based on current at the rated circuit capacity, in this case, 15 Amps.
It occurs to me that the outlet, being a general lighting outlet will have a calculated load much less than that. . .perhaps 50 to 120 VA, depending upon how many opennings are in the X ft² alloted for that circuit's portion of the General Lighting Load. Hypothetically, let's say 18 outlets on a 15 Amp circuit, or 100 VA per outlet.
To satisfy the minimum of the Code, and, thinking of 210.19(A)(1)FPN No. 4:
Would I measure the voltage drop on the farthest general lighting outlet by applying a 100 VA load (from the above hypothetical)?
