I guess things will never change. I have a home inspector who invested in that tester that checks for polarity, grounding, GFCI protection AND voltage drop. Since he has paid $300+ for his new tester he is charging $600+ for the home inspection required prior to the sale of the house. When the tester simulates a 10a. load on the end of a 150 foot long, 15a. circuit and it shows a 10v. drop he reports to the customer that there is something wrong with the wiring in the house???? What should I tell this "gentleman" and not risk offending?
