Questions and Answers for Commercial Electric Outlet Tester

A:  Hello! This means that the white wire, which is the neutral, is loose or disconnected from the outlet that was tested. It could also be that the neutral is disconnected somewhere between that outlet and another outlet that that feeds it. Hope this helps.

A:  To add, this will only show a circuit grounded if its grounded back to the panel or a copper pipe, in my experience. So if that circuit is just ground to the box, this tester will show it open ground.

A:  My guess is that circuit is old and not grounded. At a minimum you can ground it to the box, assuming its steel.

A:  How many wires did your old two prong outlet have? How did you wire the wires to your new GFCI outlet? All GFCI outlets should have one live, one neutral and one ground from the breaker box or the electric wiring system. Where is your ground wire coming from?

A:  According to Commercial Electric MS112H's manual, MS112H has 12 months warranty from the date of purchase.

A:  Yes!

A:  You can test any 120 Ac outlet. Great tool for testing home or commercial outlets.

A:  Yes Joe, home use is fine. I bought it strictly for home use.

A:  It makes no difference. It will work exactly the same in a residential or commercial environment.

A:  No, it doesn't matter. It is a 3 wires receptacle tester. It makes sure that the testing receptacle is safe for use or wired correctly.

A:  The product description states: "Detects common wiring problems in standard receptacles." There is no limitation stated that the receptacles should be "residential", because there are nonesuch, but you would need a GFCI capable tester for any GFCI receptacles, which abound in modern residential construction. The manufacturer name: "Commercial Electric", appears to be more for marketing than as a limitation on use, implying that it is suitable for commercial use. That said, there is no reason one should limit tool selection to those limited to residential use as that would imply limitation to infrequent and light duty use. Also, other Q&A suggest there are some issues with this device which would best place this tool in the hands of an experienced operator.

A:  It works fine in both. I initially bought this for receptical testing in my home, but I started taking it with me on jobs as well. Great buy if you ask me.

A:  You can use in your home just fine

A:  nothing

A:  No lights will illuminate if there is no power.

A:  No, there is no light at all.

A:  No lights will come on.

A:  nothing would happen since it tests the flow of electricity , power must be on to the circuit

A:  Capacitor discharge.

A:  My understanding is that the green light will go off as the stored power contained within the unit, dissipates..

A:  no. the indicator lights will instantly go off when unplugged. snapping a quick photo with your phone to help remember the what you need to change always helps.

A:  Dear valued customer, the tester has capacitor module, once the device pulled out from the outlet, a tiny little current will stay over at the device, then to dim away. Therefore, the tester works properly and the tiny little current will not affect and cause injury. Please let us know if you have questions in further.

A:  The manufacturer makes a separate gfci tester, the implication being that this one does not work in gfci outlets.

A:  No, there is another tester for that.

A:  Yes, it tests GFCI outlets as well.

A:  Dear Customer, Both yellow light stay steady which mean the all line has grounded correctly. Thank you and have a great day.

A:  Dear Customer, while 3 lights came on, there would be consider as two possibility result: 1: The outlet was wired without ground wire on a 220V outlet. 2: Either ground or hot wire was connected incorrectly. Per technician recommendation, please check the voltage of ground or hot wire. Thank you and we will look forward for your further questions.

A:  Bad. read the tester it will guide you.
