Methods for electrical isolation of a locator wire for locating the position of a utility conveyance include, in one aspect, the steps of positioning at least one locator wire in substantial alignment with the utility conveyance, and placing the locator wire in electrical communication with an electrically conductive terminal at least partially enclosed within an electrically isolating sheath. In another aspect, a method is provided for locating a utility conveyance, including the positioning at least one locator wire in substantial alignment with at least a portion of the utility conveyance and placing an electrically conductive terminal in electrical communication with an end of the locator wire. The terminal is separate from the locator wire and further is at least partially enclosed within an electrically isolating sheath. A detectable signal may then be applied to the locator wire through the terminal, and the location of the utility conveyance may be ascertained with a detector.
