Homes typically use insulated copper electrical wire, most commonly NM-B (non-metallic sheathed cable). The wire gauge, or thickness, varies depending on the circuit's amperage rating and intended use. Proper insulation is crucial for safety, preventing short circuits and electrical shocks. Using the correct wire type is essential for any electrical installation.

An electrical socket, also known as an outlet or receptacle, is the point in a wall or surface where you plug in electrical devices. It receives power from the building's wiring system. When a plug is inserted, it completes a circuit, allowing electricity to flow to the appliance. Sockets are designed for safe and reliable power delivery. They are a fundamental part of any electrical system.

An electrical box, or enclosure, is a container that houses electrical connections, devices, or wiring. This can include circuit breakers, switches, or wire splices. Its primary purpose is to protect these components and prevent accidental contact with live electrical parts. Boxes are made of metal or plastic and come in various sizes and shapes. They are crucial for electrical safety and code compliance.

An electrical junction box is a safety enclosure for wire connections. It protects splices and allows for future access or expansion of the electrical system. Junction boxes are required by electrical codes to prevent hazards from exposed wires. They ensure that all connections are made securely within a protected space. Proper installation is vital for safety.
