How to Rewire Your 130 Year Old House Without Burnning it Down

Assess the Current Wiring

Before beginning any rewiring project in an old house, it's important to thoroughly assess the existing electrical system. Here's what I recommend doing:

• Examine the electrical panel and take note of the type of wiring, the amperage rating, and whether it uses fuses or breakers. Very old wiring may be knob-and-tube, which will likely need to be completely replaced.

• Look for outlets with only two prongs - these indicate outdated ungrounded wiring. I'll need to replace these with modern grounded outlets.

• Check for any loose, damaged, or frayed wiring. This can be a fire hazard and will need to be repaired or replaced.

• Consider hiring an electrician to do a thorough inspection and provide recommendations on updating the wiring. Their expertise can prove invaluable for a large rewiring project.

• Test outlets and lights throughout the house for functionality and odd behavior that could indicate wiring issues.

Thoroughly understanding the current state of the wiring will help me develop a plan and budget for the rewiring project.

Develop a Rewiring Plan

With the assessment complete, I can strategize my rewiring plan:

• Prioritize safety - focus first on any hazardous wiring that poses a fire risk. This needs to be addressed before tackling other updates.

• Determine scope - decide how much I want to rewire. I may opt to only rewire some sections rather than the entire house. Focus on frequently used areas and older wiring first.

• Choose a wiring method - new cables can be run through walls, basements, or attics. I'll need to pick the most sensible routing method for my house.

• Select materials - decide which gauge and type of wiring to use. Copper wiring will provide the safest, most reliable conduction.

• Consider smart home additions - if I want to incorporate any smart home devices, I'll need to factor in the necessary wiring now. This includes things like digital thermostats, smart speakers, and internet-connected appliances.

• Develop a circuit map - draw up a detailed map of existing and planned circuits to refer to during the project. This will help avoid confusion.

• Pull permits - check with my local building department to determine if I need any permits for the project. This ensures I follow safety codes.

Having a clearly defined plan in place will make the rewiring process smoother and less prone to headaches down the road.

Safely Running New Wiring

When it's time to actually run the new wiring, safety has to be my top concern. Here are some best practices to follow:

• Turn off power - The electricity must be completely shut off at the main breaker panel before starting any work. I'll want to test with a voltage tester to be sure.

• Use caution penetrating walls - Carefully cut holes to feed wires in minimal locations. Avoid contact with existing wiring or plumbing inside walls.

• Protect wires - Secure cables properly and avoid leaving them dangling. Use nail plates when passing wires through studs to prevent accidental punctures.

• Connect wires securely - When splicing wires, choose durable connector types like wire nuts. Wrap connections in electrical tape for added protection.

• Label everything - Mark all circuits clearly on the breaker panel. Leave notes along the wiring route for future understanding.

• Test thoroughly - Verify proper operation of all outlets and lights after connecting them. Check for continuity, grounding, and polarity.

• Call an electrician if I'm ever unsure about the safety or code compliance of the work I've done. Their guidance can help avoid missteps.

Taking a slow, cautious approach will help ensure I don't cut corners that could put me or my home at risk. Patience and care will pay off.

Helpful Tools and Materials

Rewiring an old house has some unique challenges. Having the right tools can make the job much smoother. Here are some recommended supplies to have on hand:

• Voltage tester - Essential for safely checking that power is off before working. Look for a model with an audible alert function.

• Fish tape - Flexible steel fish tapes are indispensible for routing new wiring through walls.

• Cable stapler - Necessary for properly securing cables running along walls and studs as code requires.

• Wire strippers - A quality pair will strip insulation without nicking copper wiring. Self-adjusting styles are very handy.

• Cable cutters - Ratcheting cutters make tidier, more precise cuts through thick cable insulation.

• Wiring labels - Pre-printed wire labels or label maker to neatly mark all new circuits.

• Wire nuts - Corrosion resistant ceramic wire nuts provide a safe, durable connection for splicing wires.

• Electrical tape - Use high quality tape rated for electrical applications to insulate connections.

• Safety gear - Wear sturdy work gloves and eye protection when drilling or handling wires.

Investing in professional grade tools and gear suited for electrical work makes completing a rewire much more efficient and safe for a DIYer.

Hiring a Licensed Electrician

While a major rewiring is certainly possible as a DIY project, there are some key advantages to hiring a professional electrician:

• Experience - Electricians have years of training and understand the nuances of working safely with complex electrical systems.

• Identifying issues - Electricians can spot problems in old wiring that may go unnoticed by an untrained eye.

• Knowledge of codes - Electricians ensure all work complies with the latest electrical codes and standards.

• Efficiency - Professionals have the right tools and expertise to complete jobs accurately and quickly.

• Insurance coverage - Licensed electricians carry liability insurance in case of property damage or injuries.

• Licensed and bonded - Reputable electricians are properly licensed, insured and bonded for maximum accountability.

• Permit processing - Electricians can handle obtaining any required permits from local building departments.

While pros charge more for their services than a DIY project might cost in materials, the added safety, reliability, and peace of mind often make the expense worthwhile for major electrical work like a full rewire.

Staying Safe Throughout the Project

Safety should be the number one priority when tackling a major electrical project. Here are some key tips for maintaining safety:

• Discard damaged wiring - Don't attempt to patch or splice old, damaged wiring. Replace it completely.

• Never overload circuits - Adding excessive load to undersized wiring can cause fires. Stick to circuit ratings.

• Keep water away - Never let wiring be exposed to moisture. Water and electricity are a dangerous mix!

• Protect cable runs - Make sure cables are secured properly and protected from damage. Never leave live wires exposed.

• Confirm power is off - Always double check with a voltage tester that the power is off before starting any work.

• Provide adequate ventilation - Prevent buildup of heat that could melt insulation by allowing airspace around wiring.

• Monitor extension cords - Avoid using extension cords for permanent structures. They should only be temporary.

• Install smoke detectors - Have working smoke detectors throughout the home, especially near any electrical work.

• Check your work - Carefully test all connections and circuits after completing work to confirm proper function.

By placing safety first and avoiding shortcuts, I can tackle the rewire of my 130 year old home with confidence and peace of mind. With proper planning and safe execution, the risk of catastrophe is greatly diminished.
