When tripped, the fuse is destroyed, opening the circuit. A tripped fuse must be replaced with a new one after the electrical fault or overload is located.=== fuse box ===Predecessor to the modern breaker box.=== gang ===Describes an accommodation of receptacles or switches in an electrical box.=== ground ===In residential wiring, the 3 wires are hot, neutral, and ground. Either not insulated or green insulated wire. The ground is the connection to the earth at the location of the electrical system. The ground wire is not connected so as to be part of the normal path of the circuit, as a neutral is. The earth ground only carries a current in a fault or short circuit condition and is a safety precaution. === ground fault ====== hot ===In residential wiring, the 3 wires are hot, neutral, and ground. The black wire. The hot wire has voltage present and may be used to complete a circuit via the neutral, ground, or a human body standing on the ground.=== junction box ===a box used only for making connections such as splicing into an electrical circuit.The junction point of the legs in a Wye circuit.In residential wiring, the 3 wires are hot, neutral, and ground. Neutral is the white wire. The junction point of the legs in a Wye circuit.=== panel ===Otherwise known as a panel box or breaker box.=== pigtail ====== Scotchlok ===Insulation displacement connectors also known as a wire nut.The main breaker box or panel in a building is the central source for receiving power from the utility provider. A subpanel is another breaker box fed from the main breaker box panel.
