I would recommend a transformer based system to drop the 220 to 110, this will further isolate the line. Run that to a dedicated subpanel and run your system off that.
Home electrical question.
I've got a 220V line running into my basement for a dryer. Don't really need it since I'm using a gas dryer. It would be expensive to run a new separate line into the house. The 220V line line could be re-routed where I need it relatively easily. What do I need to do to convert this to a 110V dedicated line? I don't think there's anything else on the circuit although there may also be a 222V outlet for an electric stove on it, not sure. I'll have to check. Again, I have a gas stove. I would have an electrician do the work but I need to know if it can be done and some of the terms I need to know to communicate efectively. Thanks!
