Introduction
Rewiring a home can be a daunting task, but with proper precautions it can be done safely. Electrical systems have come a long way since the 1800s, so while we may romanticize the obscurity of old wiring methods, most are unsafe by modern standards. I aim to provide helpful tips on rewiring while emphasizing the importance of safety and best practices. There's no reason to risk burning your house down in 2023!
Leave Rewiring to the Experts
I strongly recommend leaving major electrical work like rewiring to licensed electricians. Rewiring requires in-depth electrical knowledge and experience working with safety codes and standards. Mistakes could lead to fires, electrocution, or other dangers. The potential risks usually outweigh the cost savings of DIY electrical work.
That said, I understand the desire to take on do-it-yourself projects. So if you plan to rewire, take every precaution and ensure you have the proper training and tools. Only take on what you're confident you can handle safely. Know when to call a professional.
Safety First - Turn Off Power at the Breaker
Before touching any wires, you must disengage power to the circuit you're working on. Turn off the breaker switch that controls that circuit. Verify power is off by testing wires with a contactless voltage tester. Failure to do this could result in electrocution.
Always double check wires are de-energized before handling. Assume wires are live until proven dead. Accidentally restoring power mid-job can have disastrous consequences.
Use Extreme Caution Working Near Live Wires
Avoid working on or near live wires whenever possible. But some rewiring tasks like installing new circuits may require working in live electrical boxes. Use insulated tools, wear personal protective equipment, and avoid contact with bare conductors.
Have an overcurrent protection plan in place. Know exactly which circuits will be affected. Exercise extreme caution and if in doubt, consult a professional before proceeding.
Update Outdated Wiring and Use Modern Materials
While obscure old wiring techniques may seem intriguing, most are unsafe by modern standards. Replace outdated wiring with new cable insulation like Romex. Use up-to-code junction boxes, conduits, and connectors. Install AFCI/GFCI outlets for protection against arcs and ground faults.
Follow national and local electrical codes, available via NFPA 70 and local permitting offices. Adhering to modern standards reduces fire and shock risks. Don't replicate questionable vintage wiring you may uncover in the process.
In Summary
Rewiring an old home comes with risks. Safety should be the top concern. Turn power off at the breaker before working. Use extreme caution near live wires. Follow modern codes and best practices, don't replicate outdated techniques. Consider leaving major rewiring to licensed electricians. A professional assessment of your electrical system is recommended before attempting DIY work. Take all precautions and only take on tasks you're confident handling safely.
