The answer to 'how to replace rewiring' is that rewiring a home is a complex electrical project that should be done by a licensed electrician. Rewiring involves completely replacing the electrical wiring throughout a home, which requires extensive knowledge of electrical codes and safety protocols. This is not a DIY project for most homeowners.
Rewiring is typically only needed if the home's existing wiring is outdated, damaged, or no longer able to safely handle the home's electrical load. Signs that rewiring may be necessary include frequent tripped breakers, outlets that don't work, flickering lights, or an old fuse box instead of a circuit breaker panel.
