The answer to 'how does rewiring work' is that rewiring a home involves completely replacing the existing electrical wiring system with new, up-to-date wiring. This process involves running new electrical cables through the walls, ceilings, and floors to power all the outlets, lights, and other electrical devices in the home. Rewiring is often necessary when an older home has outdated, unsafe wiring that needs to be brought up to current electrical codes and standards.
The rewiring process typically starts with an assessment by a licensed electrician to identify any issues with the existing wiring and determine the best approach for the new system. They will then work to safely disconnect the old wiring, install the new cables, and connect them to the home's electrical panel and individual devices. This may require opening up walls, ceilings, or floors to access the wiring, and the process can be disruptive but is necessary to ensure the home has a safe, reliable electrical system.
