For example, an SEU cable has a neutral conductor but lacks a ground conductor. Because ground conductors and neutral conductors are only joined at the point of service disconnect, SEU cables are only safe to use at the point of disconnect.

The common factors that can contribute to conductor insulation degradation because of excessive operating temperature are the ____ temperature in which the conductor insulation shall operate, the ____ heat created in the conductor as a result of current flow, the dissipation rate of the heat into the surrounding environment, and the heat generated by adjacent current-carrying conductors.
