What if my house was older and they did not run a ground wire to the outlets, will a gfi give me protection such as a ground wire would?

No, a GFCI senses an imbalance between the hot wire (black) and the neutral wire (white) presumably a situation where part of the current is going somewhere other than returning directly to the power source. A GFCI trip is also many times faster that a circuit breaker trip thereby reducing the risk to human life. Now, having said that, it is generally an allowed practice to replace household two prong receptacles with 3 prong GFCI receptacles (requires a sticker on the receptacle staring that it is not grounded) but it does not / can not replace a ground wire (green or bare) that is not there.

If the voltage from the outlet surges, any surge protector diverts the extra electricity to ground through the outlet's ground wire. If you have any additional questions, please reach out to our Pre-Sales Applications team at 773-869-1773.

Yes, it will work properly. The ground wire does not run through the circuit. This device works by measuring the current flowing from line to neutral or hot to cold. Normally 100% of the current should flow from the line through the device and back down the neutral wire. If something like a person touched a live circuit it would cause a current imbalance and trip the outlet. A hair dryer is an example of a two-wire ungrounded device that uses a gfci.

You only need one of these, attached to the main cable that comes into your house. That will stop any electrical surge that may come through the cable itself.It doesn't function like a "ground" for everything, though... The power cord of each device (TV, computer, etc.) will still need to be plugged into a wall outlet or power strip that's equipped with surge protection in order to stop surges that may come through the regular house wiring.

Any outdoor outlets need to be properly connected to a GFCI ground fault circuit interrupter. You should not use it where it might get damp. Temporary use for a dry outdoor task may be okay.

I'm sure it would. The third prong is a grounding connector. The ground wire is for protection so it doesn't serve any other purpose except that. You must have a older home like my brother where his receptcacles doesn't have a ground. You can't use any safety electrical devices like a GFI without a ground but all 120vac devices will run without a ground except the protection of a GFI.

Depends on what you call "properly". Yes it will work as a GFCI but as the other answer already noted, there will be no ground. Inside the box are stickers. One of which indicates that the GFCI is NOT GROUNDED. You will need to attach this sticker to the GFCI. The GFCI part of the receptacle will work to monitor current differences between the hot (black) and the neutral (white) wires but there will be ground connection to protect against grounds to "earth". It is generally recognized as a proper way to convert 2 prong receptacles with no ground conductor to a 3 prong receptacle. Check with your local code enforcement office for regulations in your area.

It does not include a GFIC. To add the protection, just install a GFIC receptacle between the thermostat and the breaker.

Others have already commented that the ground conductor in Romex electrical cable is bare copper. If you have no ground wire, the GFCI will still detect a current leak between hot (black) and neutral (white) conductors and turn off if the leak is greater than 5 mA. When you install it without a ground, the GFCI has to be labeled as "No Equipment Ground". The same label has to be pasted on all receptacles that are on the load side of the GFCI receptacle. While the GFCI will "work" without being connected to a ground conductor, it is far safer for it to be grounded. Although this receptacle is described as "Self-Grounding", that term is frequently misunderstood by end users and employees at some home improvement stores. As stated in the documents provided with the receptacle, be aware that it does NOT provide a ground. Self-grounding means that the receptacle can be grounded by connecting it to a metal gang box that is already grounded (if it is installed in such a gang box - frequently found in older homes). For all other installations, it is grounded only if it is connected to a ground wire.

No this is not GFI (Ground fault interrupter), you would have to install separate GFI behind the switch or between the switch and fan. -- It is a very good timer switch, and I have wired several for use in bath exhaust fans. It's advantage is that it will handle larger loads (bigger fans) then most switches.

No. As long as your devices are plugged into the surge protector it shouldn't matter what is between your surge protector and the power coming into the house.

My home is old, too. I did not have a grounded outlet available in the room where I used it, so I plugged it into a regular outlet and it worked fine. I honestly don't remember if it said that it "needed" a grounded outlet. I don't think I even got an instruction booklet with it, which I remember thinking was odd. You could probably find some specifications for this unit on the Vornado website, however, if you have safety concerns. Good luck!

Just connect the 2 wires, hot and neutral, to the GFCI. Ground isn't needed.

Indoor outlets (except for the bathrooms) rarely have Ground-Fault Circuit Interrupters (GFI/GFCI). Outdoor outlets MUST have them, by the National Electrical Code. You would be wise to buy a short plug-in GFCI (or whatever the new model's called) at the hardware store to protect yourself from getting shocked if something happens to the cord outside.

only if is pluged in by a water source but it would not hurt to plug it to a gfi if thats what is there gfi is a added safety breaker

That wouldn't be a good idea because you will be removing a built-in protection against electrocution/short circuits and I'm sure it's against the building code. I would find another outlet to replace.

I drove a 4 foot grounding rod into the ground and wired (same size of wire or larger) it to the ground lead from the surge protector. This gives the protector way to bleed of any surge and dump it to ground. If location will not allow you to drive a rod, you can run wire back to a house ground and attach to it.
