The answer to 'difference between rewiring' is that rewiring is the process of completely replacing an older, outdated electrical system in a home, while electrical upgrades involve making improvements or additions to the existing electrical system. Rewiring is a more extensive and costly project that involves running new electrical wiring throughout the entire home, while upgrades can be more targeted and less disruptive.
Rewiring is typically done when the existing electrical system is no longer safe or adequate to meet the home's current electrical needs. This can be due to outdated wiring materials, insufficient capacity, or safety concerns. Rewiring ensures the home has a modern, up-to-date electrical system that is safe and can handle the demands of today's electrical devices and appliances. Electrical upgrades, on the other hand, are often done to improve the efficiency, capacity, or functionality of the existing system without a full replacement.
