I've decided to take on the daunting task of rewiring my home. As a novice DIYer, this seems incredibly overwhelming. However, with the right tips and techniques, even a beginner can successfully rewire their house. Here are some brilliant yet little-known tips to help me tackle this project with confidence.
Research Local Building Codes and Permit Requirements
Before I start ripping out walls and rerouting wires, it's crucial that I research my local building codes and permit requirements. Electrical work often requires permits to meet safety standards. I'll call my local building department to find out exactly what is needed for my rewiring project. Knowing the legal guidelines ahead of time prevents expensive mistakes down the road.
Map Out a Plan for the New Circuit Layout
Rewiring a home is a big job, so having a solid plan is essential. I'll start by drawing up plans for where I want new lighting fixtures, outlets, switches and other wiring components to go. I'll also map out the circuit layout, marking where different runs of wire will connect various parts of the house. With a detailed plan in place, I'll have a much smoother rewiring process.
Label All Existing Wires and Circuits
Before removing any existing wiring, I need to identify what each wire is connected to. I'll flip breakers off one at a time and thoroughly label each wire with masking tape based on what turns off. For example, I'll write "kitchen outlets" on the wires that control the kitchen when I turn off that circuit. This prevents confusion later when I'm ready to reconnect the new wires.
Consider Running New Wire Through Walls and Attic
Rather than just reusing existing wire runs, I have the opportunity to route new wiring through walls and attic spaces while renovating. This allows me to create an efficient and organized wiring system. I can run wires vertically through interior wall stud bays, horizontally through drilled holes in wood and metal studs, and above the ceiling through the attic. Accessing these routes takes more work but yields a higher quality rewire.
Use the Right Wire Gauge and Type
Selecting the proper wire gauge (thickness) and material is vital for performance, safety and code compliance. For standard 15 amp household circuits, I'll use 14 gauge copper wire. For 20 amp circuits, like for large appliances, 12 gauge is required. I'll choose quality copper wiring over cheaper aluminum wire, which can cause hazardous connection issues over time. Using the right wire materials and thickness prevents electrical hazards.
Incorporate a Ground Wire in Every New Circuit
Modern electrical codes require a ground wire in addition to a hot and neutral wire for each branch circuit. The ground protects against shocks and electrical fires. As I run new wiring, I'll be diligent to install a ground wire for each new circuit I create. I may need to run new wire with a ground back to the main electrical panel in older homes where grounds were not common. This provides essential safety for all new wiring.
Create Separate Circuits for Heavy Appliances
When rewiring, it's wise to move large appliances like the refrigerator, electric range and washer/dryer onto their own dedicated circuits. This prevents overloading a circuit and tripping breakers. I'll run individual wires from the main panel directly to each major appliance. While more work upfront, separate circuits help ensure reliable power.
Upgrade the Main Service Panel if Needed
If my home's main service panel is old or undersized, it may need to be replaced to support updated wiring. Newer 200 amp panels are preferable. I'll hire an electrician to install a new panel and safely connect all my new branch circuit wiring. Upgrading the main service ensures all the hard rewiring work I do is supported by modern equipment.
Take Precautions Not to Overload Existing Wires
As I upgrade wiring in phases, I need to be cautious not to overload existing wiring that is still in use. I'll avoid using high-wattage appliances on older existing wiring. Overloading wires risks fires from excessive current and heat. I'll work carefully to balance electrical loads until the rewire is complete. Taking it slow protects my home.
Inspect All Work and Fix Issues Before Turning Power Back On
Once the rewiring is finished, I'll meticulously inspect every connection point, junction box and wire run before re-energizing the circuits. I'll repair any loose connections, ground faults or defective cables. It's crucial that all electrical work is perfect and up to code for safety. Only after thorough inspection will I turn the main power back on.
With proper planning, care and attention to detail, I can successfully rewire my home without issue. Following these brilliant yet little-known tips will help me avoid costly mistakes and end up with a beautifully renovated electrical system that meets all safety codes. This project will take time and diligence, but will be well worth it in the end for upgraded electrical safety and performance.
