Is grounding to the box adequate for a neutral or must it have a third wire?

Grounding the neutral is not allowed per electric code. The EI 600 model is the same timer but does not require a neutral wire.

You will need a neutral conductor to meet your local electrical code requirements.

You should ask an electrician why it needs one, but I know it won't work without it being grounded.

You would be better off the changing the two(2)prong outlet for a three(3)prong.for ground protection.And for a two or three dollars investment,you will be safe

My previous set up was 3 wires. 2 hot and a ground. I did a few searches and was told that this unit did not need the ground wire so I left it disconnected as there is no place to connect it. The unit has been working fine for 8+ months now.

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.

No grounding is needed. All you do is hook up the coaxial cable and the power source can be close to your TV.

If I understand your question correctly the answer is yes. That's a pretty standard set-up and it was designed to handle that exact situation. Of course you have to have power running to that outlet for it to function. Grounding and polarity have to be right too.

For the device to work, you must have the ground wire connected to a ground source or third wire that goes to the ground.

I use it without grounding and no problem. It is a general rule for any electrical equipments tp avoid shock in case an electrical leak to the metal parts.

yes, these are much like a standard switch which does not require a neutral. You will need to ground the switch however.

I believe it did require a neutral wire. If I remember my installation correctly it didn't simply drop in place of the hot switch it replaced

I think it does not need it. But instructions say ground wire is highly recommended. My take: since there is circuitry imbedded in the unit, the ground keeps it from getting fried. I wouldn't install without ground.

You need to run 12/2 wire with a ground. So, three wires. Black to one leg of 220, white to the other leg, and bare to ground. No neutral is required.

The neutral does not need to be connected. The voltage across the red and black is 240V and the white is just a center-tap on that potential, meaning the voltage between white and red (or between white and black) is 120V and this unit does not need both 240V and 120V at the same time. Be sure to cap off the unused white wire.

Older installations won't have a matching ground wire. The ground wire is for safety, but not strictly necessary. Simply cap it off as you do the other leads and be very careful none of the wrong wires touch each other when you push the box in.

Hi, it counts on your wiring. If the box is ground and you use the screw in the loop then yes it will be ground. If the box is not then of course a ground will not just appear from no where.

Yes you ground your device anywhere you find a good ground and then run your red(positive) wire to the fuse box using the Add-A-Circuit.
