Page 9: Unpacking And Inspection
INTRODUCTION The INSP-3, wiring inspector is a rugged tester designed to verify building wiring compliance to electrical code, especially voltage drop under load. Identify issues with splices, connections and conductor quality, crucial to safety and performance of the electrical system. - Page 10 • Meter detects faulty wiring in need of repair without removing outlets cover plates, or panel covers: • Faulty splices and connections • Incorrect wiring • Undersized wiring • Faulty GFCIs, • Faulty or incorrectly wired AFCIs • Incorrect line voltage • Poor ground quality • User selectable 10,15 and 20 amps loads to verify performance of the electrical system • Incorrect wiring or voltage drop test failure is clearly indicated by flashing screen • Will not trip circuit breakers or blow fuses during the test • Tests GFCI and AFCI operations • Check ground quality for safety and ability to...

Page 11: Operation
Ground impedance and polarity is not tested on 2 wire outlets. 1. Push GFCI TEST push button or AFCI TEST push button before plugging the INSP-3 to a GFCI or AFCI circuit outlet to be tested. 2. Plug the INSP-3 wiring inspection tester into an energized 120V wall outlet using the power cord provided. -

Line 2: shows the polarity status Line 3: The “SET LOAD” switch is set for a test drawing 15 amps. At 15 amps of current draw, the voltage at the outlet would drop by 4.2%. Since 4.2% is lower than the NEC recommendation of a maximum of 5% drop, it would not be flashing. -
Page 13: What The Readings Mean
the wiring resistance would limit the current to approximately 424 Amps. Line 5: shows that if the hot and ground conductors were to be shorted at the outlet, the wiring resistance would limit the current to approximately 850 Amps. NOTE: Unit turns on automatically when plugged in. - Page 14 loose connection or if the wiring run is too long or has too small a gauge wire for the length of the run. The electrical code states that “. . . where the maximum voltage drop on both feeders and branch circuits to the farthest outlet does not exceed 5 percent, will provide reasonably efficiency of operation”...
- Page 15 and high technology electronics are reliant on a good quality equipment ground for proper operation. A typical rule of thumb is ground resistance in most cases should be less than 2 ohms. Loose connection, splices or too small of a ground conductor can cause high impedance.
