Is this comptabile NEMA 6-20p/6-20 R 240V 20Amp? In the description it only says for heavy duty 240 V.
I do wish amazon had a better picture of the Plugs or the Type in the details.
One person here says it is?

does buying the incorrect item on your part really qualify as a review?
I should hope you know the difference betwen 240v and 120v, if you do not! hire an electrican.
Particular Plugs are desgined for particular applications.. ( i.e. NEMA 6-20p/6-20 R 240V 20Amp can not plug into the 120v stanard lamp outlet and helps to keep tards from burning down the house )
Reasearch before you buy???? That is what I am doing???

In the heat of summmer, I got tired of walking into my apartment at the end of the day only to have it be sweltering hot. I have a wall mounted AC with no timer so I decided to buy one. After much research and a lot of dead ends, I finally came across this product. My AC now turns on 20 minutes before I get home and my apartment is nice and cool. Make sure to search around to ensure this model fits your outlet! Intermatic offers similar models with different plug designs so make sure to get the right one. I have used this timer for over a year now and have yet to have any major problems.

You can find a pdf with the complete specs here: [...].

A few words on how this product works, the HB112C is a simple timer that controls when a high amperage appliance (such as an air conditioner) receives power. On the face there is a 24hr clock with notches at 1/4 hour intervals where you can insert the start (red) and stop (black) pins. Each timer comes with two sets of pins that essentially allow you to turn your appliance on and off twice per 24hr period. The pins work by turning a black nob located on the front of the timer. This same nob can be turned manually at any time to turn the appliance on or off. The 24hr clock is reasonably precise but it does tends to gain time if turned on & off frequently (at worst 20-30 min over the span of a week). It is, however, extremely easy to reset the clock to the proper time.

I'm not sure what else this device would be useful for, but as an AC timer it works great. I wouldn't want to go another summer without one.

I was unable to use this item It had two vertical prongs. My husband thought it was European. Apparently you have to be an electrician to properly purchase these things.
