Plugging in a Speedaire compressor: what voltage?
by Fred
I have an older Speedaire compressor. The model number is 3Z355B (sorry six characters not five as posted). It is a two cylinder, single phase compressor that can be wired either 230V or 115V. Bill says... don't worry! Hi Fred. No, I'm not an electrician, but I have to believe that you can't plug a 110 VAC plug into a 220 VAC receptacle, and vice versa, as the two types of plugs are incompatible, in order to help people identify the two. Have you a clothes dryer? Have a look at the plug for the dryer. Clothes dryers are often 220 VAC, and if yours is, you will see what I mean about an entirely different plug. Plug your compressor into a 110 VAC receptacle, and see what happens. Make sure the tank drain valve is closed, and of course, that there are no obvious issues with compressor maintenance, such as bare wires, wires off... you know, that sort of thing. Also, look at your compressor plug, and the 220 receptacle behind your dryer. If the dryer is 220 VAC, then your compressor plug, as I interpret how you've described it, just won't fit. Last, I believe if the compressor is dual wired inside, you need to make a change in the supply plug to provide the appropriate power. Anyone else have any suggestions? And Fred, thanks to him for visiting this website and for writing in. Cheers, Bill
