Can this be used to test a non-GFCI outlet?

Yes... as long as it is a 3-prong outlet, it will test for polarity and proper grounding. The only part of this that is for the GFCI plugs is the push button which drains off a little current. If you push the button on non-GFCI plugs (or non-functioning GFCI plugs), nothing will happen. BTW, this is one of the best testers like this that I've found.

I did, but I'm not sure I should have. Nothing bad happened to the outlets, but it didn't seem to register a response. As I recall, the instructions said it was for GFCI outlets only - of course, I read it AFTER I used it in non-GFCI outlets. I hope this helps you.

No. Tests for presence of electricity and proper wiring of outlet. Also tests for proper operation of GFCI.

It so does protect againt surges. Those people writing negative reviews more than likely did not have a properly grounded outlet. It will not work without a ground! Get a circuit tester at any hardware store for about $5.00 (a lot cheaper at Harbor Frieght) and make sure your circuit is good. Besides the ground test, it will test the polarity on your circuits, and any GCFI's you have. Easy as pie to read ... not so easy to fix if you DON"T know what you are doing. Good luck -jay

Yes and No. The USB ports are powered and the surge suppress indicator works. I have mine plugged into a GFCI outlet. This device is designed to be attached to a standard duplex outlet using the supplied screw that mates with the screw hole for a standard wall plate. This cannot be done with a GFCI. I use it by being careful to hold the device when pulling cables out.

Yes it will. A very handy tool when rewiring outlets or just checking for power.

Hi, thank you for contacting us. I'm afraid the tester can only perform test when component is NOT in circuit. With best regards, Kevin

It test the polarity etc. of a regular receptacle. It does not trip the breaker in the panel that feeds the receptacle. Hope this answers your question.

Yes, this would be an excellent use for this tool. Be sure to check a known power source such as a receptacle to ensure the tester is working properly.

Should be able to test 6 volt battery one at a time, not all connected together.

Yes, in some cases you can detect the wiring, but I have not found it to be 100% reliable.

Plugging in the tester plug into any receptacle will identify which line it is on no mater how many outlets are on that circuit.

I just tried this for you, and yes - it will check resistance between neutral and ground, and alert if they're connected together.

I think so. It only has prongs for one outlet. It has a plastic prong for the bottom half of the outlet, just for support. I had to break the plastic part off with pliers to get it to fit in my GFCI outlet. The spacing between the top and bottom must be different than a standard outlet.

Yes, but if you need test resistence this devices dont do that.This device working for continuity.

No, it is only a 120vac outlet tester. If you some how get it plugged into a 220vac outlet, you will most-likely burn it up.

This is just a simple electrical tester. It sends a pulse down each wire to see if there is a response on the other side, i.e. it doesn't traverse switch ports.

Yes, any three prong outlets. It won't test dryer plugs or oven plugs. It does test regular and GFI outlets
