Neutral Bar
A Neutral Bar, sometimes called a neutral bus bar or neutral terminal strip, is an important component in electrical installations. It's like a central meeting point where all the neutral wires from different electrical circuits come together in an electrical panel or breaker box. Think of it as a gathering spot that helps organize and safely connect all the neutral wires, which are essential for completing electrical circuits. This is a basic but crucial part of any electrical installation, whether in homes, offices, or industrial buildings.
