Rewiring and electrical panel upgrades can be extremely complex. You have to think about the load on the panel. If you need to add a breaker, or if you’re rewiring your home because it’s outdated (like knob and tube electrical), then you’re talking hundreds of feet of electrical wire that needs to be restrung through your home. That’s no small task! Not to mention the need to follow building codes for your area and potentially submit permits, depending on your project. Because of the complexity of rewiring and electrical panel upgrades and the potential for electrical fires and electrocution, we will always recommend that you contact a professional electrician who has years of experience in this kind of work.
