Classic manual knockout punches are operated with a socket wrench.

A knockout punch set gives you the choice of many different sizes of knockouts. A knockout punch is an electrician’s favorite tool for making new holes in an electrical box or panel. Knockout Set – Known more specifically as an electrical knockout set or knockout punch. Ground Fault – A ground fault is an unintentional, electrically conductive connection between an ungrounded conductor of an electrical circuit and the normally non–current-carrying conductors, metallic enclosures, metallic raceways, metallic equipment, or earth. Grounded (Grounding) – Connected (connecting) to the ground or to a conductive body that extends the ground connection. Grounded Conductor – A system or circuit conductor that is intentionally grounded. Ground Fault – An unintentional, electrically conductive connection between an ungrounded conductor of an electrical circuit and the normally non–current-carrying conductors, metallic enclosures, metallic raceways, metallic equipment, or earth. Ground or Earth - The reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth. To restore service, the fuse must be replaced using a similar fuse with the same size and rating after correcting the cause of failure. Feeder pillars act as a central circuit that controls and distributes electricity to outgoing circuits downstream to the feeder pillar.įuse - A circuit interrupting device consisting of a strip of wire that melts and breaks an electric circuit if the current exceeds a safe level. DC current is an electric current that flows in only one direction.įeeder – All circuit conductors between the service equipment, the source of a separately derived system, or other power supply source and the final branch-circuit overcurrent device.įeeder Pillar – A feeder pillar (also known as a power box or distribution pillar) is a cabinet used to house electrical equipment. This is an electric current that reverses its direction many times a second at regular intervals.ĭC (Direct Current) - DC stands for Direct Current.
