Editor's Pick: When a breaker trips at home or you suspect a wiring issue, just plug this in — the backlit LCD screen directly reads voltage and wiring status, so you can spot a reversed wire at a glance. It also shows trip time when testing GFCI outlets, making it handy for renovation inspections or checking for hazards in older homes. The AutoHold feature is great for outlets behind the couch that are hard to reach — the reading locks in so you don't have to crane your neck to see it. Two AAA batteries are included, so it's ready to use right out of the box.
