Greenlee GT-10GFI

Electrical Supplies Online is offering the Greenlee GT-10GFI electrical tester for $8.82 today.  They’ve also got the GT-10 “polarity cube” (read: the same thing, but no GFI) for $5.18.

If you’re doing any re-wiring in your house — especially an older house — this (or one like it) is a must for your toolkit.  It’ll test any 120V grounded or GFCI outlet, and its various light sequences indicate proper and improper wiring.

    Harbor freight sells these for only a few bucks – get them in the store rather than ordering the ones here: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=32906

    They work great and I believe they have the GFCI and non-GFCI versions.

  2. I have the one similar to the one you listed on Harbor Freight that has the GFCI test in it. I gave the one without the test that I had previously gotten to my friend.

    These GFCI testers make life very easy when you run receptacles off a GFCI breaker or a GFCI receptacle. The problem with not doing testing is that if you improperly connect the line/load configuration, you can have a GFCI that is functioning like a regular receptacle. This gives you nice “warm fuzzies” when you’re testing a regular receptacle that is hooked to a GFCI somewhere down the line. Otherwise, how do you know it’s really working? GFCIs fail over time anyway.

    This tool is totally work the chicken scratch you will pay for it, even the Greenlee.

    Is the Harbor Freight one just as good as the Greenlee one? It was my impression that Greenlee makes quality stuff?

    I’ve seen both – I’d go with the Greenlee tester.

    I’ve used the Harbor freight version, the GB, and the Greenlee. Prongs on the others (cheapos) tend to get loose and you have trouble getting correct readings, especially if you stick it in 25 to 50 receptacles each day. Buy the Greenlee if you intend on giving it some real use. Buy the cheapos if you’re just gonna use it around the house once every blue moon.
