So I'm reconnecting my little ProtoTrak bed mill, and looking at the label on the electrical box that says "Caution, disconnect Both 110v and 220/440V power before working on this machine". I find myself wondering why this is the only machine I have that is wired like this. We like to move this around the shop as needed and if there was only one connection it would be less work to drop a single line and not have to snake an extension cord to the machine each time, plus that would leave one less cord to clean up around and/or get damaged. I've even been tempted to put a small transformer in the box to make 110, there's plenty of room. The control won't start with only 110 connected, it needs both or the monitor stays dark.
Most machines I have have control transformers to make 110, some only have one to supply an outlet for a trouble light or other tools for a tech. I'm not certain this even meets all NEC rules.
Anyone here know a good reason for this?
And yes I did ask Southwestern once upon a time and got the answer - "It won't run if you don't connect both wires". Duh.
