I need to replace my A/C in the living room. The old unit use a 240V outlet. I notice a lot of new A/C with over 10,000 BTU uses a 120V outlet. Can I plug a 120V A/C into a 240V outlet? Are there plug adapters that will make the 120V A/C plug work with the 240V outlet? Thanks.

Hi, I am new to the forum, but I am hoping someone can help me with what I am sure, or at least I hope, is a very simple issue. My fiancé asked me to replace the ceiling fan in our bedroom with a new one with more light. I assumed this would be no big deal and agreed. I took down the old ceiling fan no problem and when I did, I found an unexpected number of wires in the junction box: Total of 9 wires, none labeled or color-coded in any way. There are two bundles of 4 wires each and one single wire. I am pretty sure that the two bundles of wires are positive and negative and the single wire is ground, although I did not get a really good look at them until after I disconnected the old fan so i could be mistaken. When I connected the new fan the way I thought it should be (that is 4 wires to positive, 4 wires to negative and the single wire to ground) the circuit blows as soon as I power it on. When I disconnected the single wire from the fan's ground, the fan worked, but the light switch that controlled the old fan did nothing. In other words, with the fan's positive wired to one set of four wires and the fan's negative wired to the other set of four wires the fan turns on, but the light switch does nothing. Also, this configuration sparked and shorted after a few minutes so I am pretty sure it was not right. So now I am hoping that someone on here can give me some clue how to wire this thing, or at least what my problem might be and how to test it. I can have an electrician come in and wire the thing for 5 times what I paid for the fan, but I want badly to avoid that. Any advice is appreciated. Thanx. Dan
