Don't make this electrical mistake when connecting wires to an outlet or a switch. The back stab or quick connect feature offered on 15A residential grade devices is not reliable in my opinion. These are very tempting since they are so quick and easy to use but they often become problematic later on. In this video I will show you what they are and how to use them, why I think they're a mistake, two better options for connecting wires and then we'll take a receptacle apart and see the issue which makes the connection fail over time.
