If this switch doesn't require Neutral, why is there three wire with ground???

The EJ600 does require a neutral. The EJ500 and EI600 do not. See http://www.intermatic.com/Products/Timers/InWallTimers/Electronic_Timers.aspx http://www.intermatic.com/Products/Timers/InWallTimers/Electronic_Timers.aspx has Intermatic model differences and MUCH better programming instructions than printed instructions that come with the timer. The EJ600 replaced a EJ500 model which was still working well after 15 years. Replacement was necessary to properly use LEDs in outdoor lights. LEDs on the EJ500 model would briefly "flash" when off. I like the astronomical feature which allows lights to be turned off or on precisely at sunset or sunrise. Longitude and latitude is "automatically" determined by the EJ600's cleverly designed program when the owner enters the time zone and then manually corrects the displayed sunset time to the time of that day's actual sunset time. This corrections is only required once- at initial setup. My lights go ON at sunset and OFF at 11:00 pm and then ON at 7:00AM and OFF at sunrise (if sunrise before 7:00AM, the lights don't go on at all). One star taken off because the programing instructions were more complicated than necessary because they were written to save paper. PS: The EJ600 does need a neutral wire whereas the EJ500 does not. Most homes will have a neutral wire in the switch box . Intermatic does sell a timer (EI600) that does not need a neutral wire but it is a few dollars more expensive (and can handle larger electrical loads required by motors, etc), The EJ600 has an internal rechargeable battery whereas the EJ500 and EI600 has replaceable batteries.

The prong on the side by itself is the ground for the light on the switch. The other two are 12v in and out.

The short answer is yes. The long answer is that a light switch without a neutral wire will either not function or immediately fry if operated, depending on how modern your wiring. You will have great difficulty finding a light switch without a neutral wire. I imagine it would be illegal.

Don't know how to work with 2 wires. This switch took three wires: blue for load, black for hot line, and white for neutral line. You need to have three wires to make it work.

We haven't been able to install this yet, so I can't comment. The house we are temporarily in does not have grounded switches.

It does not require neutral, but if you want to use a "Matching" switch (one with LEDs on it) in a three-way/four-way installation, you must have a neutral wire. Otherwise, you can use a "Companion" switch (no LEDs) and not need the neutral wire for three-way/four-way.

There is no simple way for a homeowner to add a neutral wire to an existing switch box. You should hire an electrician for safety reasons. Also, this is a single pole switch and will not work as a 3 way switch.

I grounded my switch to the box and it works perfectly. I don't have ground wires either. You do need a neutral wire.

The switch gets its power by using the ground connection as a neutral, so it's running a small amount of current between live and ground. It's not a lot of power, just enough to run the detection circuitry, but it might draw enough for your GFCI to notice when it flips the relay.

Yes you're right. In fact there are five wires a ground and also an additional wire for like a two way switch location. I also recommend installing a surge protector in your load center because these electronics are very sensitive to Lightning strikes.

Yes, it requires a neutral wire, and the Product Description should really state that clearly. I do not have a neutral wire and did not find out that I had the wrong product until I saw the package.

Yes, you can install it without the ground wire. Just leave the ground (green) terminal on the switch un-connected.

Mine has three. Wouldn't make any sense for it to take grounded plugs and then straight up not ground them!

No. It's basically a dumb switch. It sends a pulse to the primary via the traveler wire of a traditional three way set up and the main switch works the light. It needs the traveler,neutral and ground.

It is a 3 way switch so the ground and 2 others are normal switches and the other is what will allow you to turn on the switch at the other switch if needed. I am no electrician but was still able to set up on my own (not recommended for just anyone to set up).

I have a regular three wire switch and it installed nicely. I don't recall it having a forth wire.

I don't think you can since no ground implies no neutral. You need the neutral.
