I'm very confused about few things electrical.
-Normal(standard) house hold electrical outlet is how many volts?
-I see that some power tools vary from 110,115,220,230 voltage and this confuses me like crazy. Let's say I get a drill press that decribes 115V/230V, does this mean it can run on either or? or is one default and the other I have to rig?
-IF standard house hold voltage was 110V, can i just plug in 115V system or do I need to change somthing?
-IF 110V and 115V can be interchanged without any modification to the tool or house electrical system, why would one manufacturer in USA state 115V on one of their tool and 110V for the other?
-I'm in a building that is roughly 75 years old. If I get a dust collector that states 220V, how do I make this work?
Thanks!
