Subpanels are an important part of a home's electrical system. They provide extra power outlets, allow for circuit breakers to be easily switched off, and help protect against electrical shorts and fires. However, correctly installing subpanels requires understanding some fundamentals, including how to wire ground and neutral lines.
In order to maintain the integrity of the electrical system, both ground and neutral wires should be wired into the subpanel. Ground wires should always go to the green screw or terminal on the subpanel. Neutral wires, on the other hand, go to the silver-colored screws or terminals. It is also important to ensure any wires connected to the ground and neutral terminals in the subpanel have the correct gauge size. Too large of a wire can overload the system, leading to dangerous situations.
Ground wires help prevent electric shocks by providing a path for current to flow to the ground. This helps protect people and electronics from the effects of electrical shorts or surges. Neutral wires are responsible for fluxuating the electric current between the subpanel and the main panel, fulfilling their role in safety and keeping power balanced. It is therefore imperative to ensure these wires are properly installed and inspected to guarantee a safe and efficient electrical system.
