Updating 2 wire outlets
It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires.
Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. The Plug-In Outlet Tester This is the first tool I grab to troubleshoot a problem with outlet circuit wiring.
Electrical Tools Required: Basic Electricians Pouch of Hand Tools, a Voltage Tester and a Multi Meter.
Estimated Time: Depends on personal level experience, ability to work with tools, work with electrical wiring, and the available access to the project area.
Luckily, metal boxes attached to armored, or BX, cable—a type of wiring commonly found in old houses—generally are grounded; the cable's flexible metal jacket serves the same purpose as a dedicated ground wire. Insert one prong of a circuit tester into the receptacle's hot slot (the shorter one), and touch the other to a screw that secures the cover plate.
To replace two-prong receptacles, just follow the steps below.

This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
They act and protect your outlets in the same exact manor.
NEC code rule 406.3(D)(3)(a) states that a non-grounding type receptacle (s) shall be permitted to be replaced with another non-grounding type receptacle NEC code rule 406.3(D)(3)(b) states that a non grounding type receptacle shall be permitted to be replaced with a ground fault circuit interrupter.
If grounds are required can you just change them with the ground fault outlets? Shawn in Wisconsin Ok here are you only options when dealing with old two wire circuits: The NEC specifically states that if you have ungrounded outlets, and you want to upgrade to polarized outlets, meaning 3 prong you have 2 choices.
You can either re-wire the entire house to meet the new NEC codes, or you can swap them out with GFCI's. If you dont want to replace all of your outlets with gfci's, then you can simply install gfci breakers.
