New to "higher" voltage Hi all, new to the site and I'm looking for a little guidance. I'm new to working with higher voltages (kV) and I am wondering what the difference is between using 13.8kV and 14.4kV. I'm dealing with some equipment vendors and one has specified 13.8kV while the other used 14.4kV. Other than the obvious, what am I missing. Thanks!!
