Okay, so upon further inspection (I feel like I find something new each time I look). I notice that there is a 220V in my basement that is not being used. The hot wires were capped off to allow for additional space on the panel, but the neutral is still connected. Since this is not currently hooked up, can I remove and cap the neutral, which would provide the one open space I need for the dedicated circuit (and be legal)?
I'm guessing my panel is not newer, probably 1980's, so I would just double them up I guess If the above isn't going to work.
