![]() ![]() ![]() leg to leg, it is just fine.īottom line, I still don't even know what you are really trying to do but the distance, ease of rewiring, etc would all dictate which route you take. High leg is only a problem when it is referenced to neutral. This is also how many machines deal with the delta high leg issue. Obviously if it is insulated properly, there would be no foul there.Īs mentioned above, the way machine tools usually do it is they use a step down isolation transformer so the potential of your 2 legs to make 240V become 2 legs to make 120V. In a Romex wire, you have 3 insulated conductors and 1 bare conductor. The ground conductor cannot be used as a neutral because it is usually bare, without a thermal/electric rated insulation. Lastly, as you say you have two live wires and one neutral, I am working on the assumption that you are wiring up single phase devices (sounds like you're wiring a phase converter for the mill?) Surely less than the cost of running a new breaker and line from your main box. Failing that, you can buy a transformer that will take 220V and step it down to 120V. ![]() The easiest course of action would seem to be to change the leads on your equipment if it is dual rated 110/220V. Suddenly you touch something and that power goes to you instead of the "ground". Using your Ground as Neutral can be dangerous for this reason. Neutral is connected to things such as your conduit or light switch box. but based on your question, I expect all of your equipment is rated at 60Hz?ĭO NOT USE GROUND AS NEUTRAL. "European" 220V power is not the same as what you wire up in the US as 220V because it operates at a different Hertz. ![]()
