Re: [CAD_CAM_EDM_DRO] Re: power supply connection issues

Jerry,
Be careful, they may get you for practicing "electrician" without a
license. There are a lot of cities whose electrical code will not allow
romex. I personally prefer flex, and try to oversize it slightly. Then, if I
have to pull in any additional service in the future, I have the space.
