“The problem with those neon light testers is that while they detect most problems, there are some very dangerous situations — ground/neutral shorts (aka “false ground”), excess impedance in the lines, voltage drop under load, among others — that they miss entirely.
“Both models of SureTest analyzers, the 164 and 165, test for all of these (including voltage drop over three different loads –12, 15, and 20 amp), as well as giving you a true RMS readout of the hot-neutral voltage and ground-neutral voltage, a peak hot-neutral voltage, a frequency reading in Hz, a measure of the available current through the breaker in a worst-case-scenario dead short of all three conductors, and a test of the GFCI if you’ve got one installed — this even includes a reading of how much current it took to trip and how long it took to trip!. The more advanced 165 model adds testing of AFCIs and another related test or two.
“I recently replaced my no-longer-manufactured Ecos AccuTest circuit tester with a Suretest 164, and am in love. (I went through a “new toy” phase of running every test on every outlet in my apartment).
“As a live sound engineer, I use it all the time to test power at a venue before I plug my (or, perhaps more importantly, my boss’s) expensive equipment into it, but it’s equally important for homeowners, where many of these problems can be the cause of electrical fires.”
Street pricing starts around $225 for the Model 164.
