She is a writer and fact checker for TripSavvy, as well as a fact-checker for The Spruce. Often it is recommended to wire nut the hot and neutral (white and black) wires together (assuming this line is now dead). If the connector is passing a current at or more than its rated current, a poorly terminated connector could easily have to dissipate much more heat than it is designed to do. The blades can be changed after some time if the initial ones become dull. What code says that tape alone is not a proper termination? E.7 maximum temperature reached by any connector during testing must be recorded. Follow Up: struct sockaddr storage initialization by network format-string, About an argument in Famine, Affluence and Morality. Screw a blank electrical faceplate over the electrical box.
