Hi,
Thought you guys would be able to help me on this.
Why would my 220 volt table saw hum when its plugged in and not running. It is in a newly built shop about 60 feet away from the main house. I noticed this the other day when I went in, so I unplugged it. It was fairly cold (35 degrees) in the unheated building. It runs fine when being used. All the wiring seems to have the right polarity. When I turn on the fluorescent lights they hum also until they warm up , but I know that is normal. I am stumped as to why the saw would hum without even being turned on.
Thanks in advance for your thoughts, Yanni
