does this need a ground wire?

This timer is in our front hall and turns on the outdoor low volt lights and one standard volt light pole with 60 watt bulb. IT DOES NOT NEED TO BE GROUNDED. This timer has two wires: one red and one black. Just wire the black to black and the red to red. We reset it several times a year for long and short days. It is quite reliable.

The switch has 3 wires sticking out from it: black, white & green. Although I'm not an electrician, we attached the green (ground) wire to the metal electrical box, just to be safe. Good luck!

I put one in the garage for the outside lights and did not ground it. I just screwed it to the box. It worked just fine.

As I recall, the switch has 3 wires that need to be connected. One wire is connected to the power source (hot), one wire is connected to the neutral, and the third wire goes to the load (light or receptacle, or device). This switch requires a neutral connection. I do not recall a ground wire or connection. I have used this device for a year, and found it to work just as advertised. The wire leads are 12 gauge wire.

There is ground wire attachment point on the front to attach a wire to run to a ground point. It will work without the ground but most generator manufacturers now recommend using an external ground for additional safety.

It comes with wires to wire it in with but they are fairly short so you will need more wire probably. I did.

I haven't purchased this yet, but if there is no ground wire connection on the unit, then you just connect the ground wires from the incoming cable and outgoing cable together in a plastic box. If you do use a metal box, then you should run a pigtail ground wire to a grounding screw in the box to ground the box, but it would be easier to just stick with a plastic box so you don't have to worry about grounding the box.

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

There is no ground wire input. 1 in 1 out 1 power input and thats it. Noiseless on my stereo. Great turntable pre-amp for the money.

yes, if you wire it correct. there are only three wires, ground, positive and negative.

There is a way to ground it, but you must do it through a separate amp. Hope this helps!

Yes if you connect only the line and neutral to the unit and unit is not grounded in through its mounting. I mounted this unit in a car, which is obviously not connected to the earth ground because of the tires. During a power outage, I plug a 10AWG extension cord into the unit. The line and neutral of the extension cord are wired to a power transfer switch (not the ground wire as mentioned earlier). I have powered the house this way without tripping the CFCI outlet on the unit.

It's a three prong plug, so if concerned about safety; yes it needs a ground (three prong outlet). As far as dedicated circuit, its powerful, but not like an big industrial motor, so dedicated circuit is not needed.

There is no ground wire provided with the timer but the timer bracket is metal and the instructions are to attach house ground to the bracket.

To be perfectly honest im not too savvy with electrical but I know it does have the ground that plugs into the wall. I have had no problems witth it

I do not know. I ended up not using it because it required an additional ground wire, which I do not have.

Just because this unit didn't come with a ground wire dose not mean you can't make one. Find a metal area on the frame of the unit-there should be a screw there somewhere to connect a wire and connect the other end to a metal area on the receiver-there should be a screw there also. I really hope this works for you-good luck.

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.
