Problem with 220 Line?I am in the process of installing a subpanel using a pre-existing 220 line that is not being used now, but was used for a water heater. The problem is, measuring accross the hot wire and ground I get a normal reading of 115. Measuring across the neutral and ground I get a reading of 94v. at the main panel, both lines read correctly, 110-115. The cable from the main to the subpanel is short, not more than 3 feet. Both boxes are the old edison type fuses and have been converted to s type. Any input would be appreciated. thanks. Randy
