The more you study and practice wiring fundamentals, the more comfortable you'll become working with electrical systems. But always consult local building codes for regulations.

Essential Safety Tips for Wiring Your Home

Electricity must be treated with extreme caution. Here are some key safety precautions to take when wiring a home as an amateur:

• Turn off power - The power source should always be switched OFF and verified at the breaker panel before starting any work.

• Personal protective equipment - Wear rubber-soled shoes, gloves, long sleeves and safety goggles when handling cables.

• Mind aluminum wiring - If your home has aluminum wiring, extra precautions must be taken due to fire risks. Consider hiring a professional.

• Use caution with cables - Never nail or staple into cables. Secure cables properly and handle with care.

• Double check connections - Faulty connections can lead to arcing, sparking and fires. Double check all splices, connections and terminal screws.

• Test wires before touching - Verify power is OFF with a non-contact voltage tester. Never assume a wire is safe to touch.

• Call for inspections - Local building codes likely require inspections from the city electrical inspector at certain milestones.

• Know when to call a pro - Some wiring projects like the main electrical panel should only be done by licensed electricians. Know your limits.

Slow and steady wins the race. Rushing leads to mistakes. Follow safety protocols and you can wire like a pro.

Choosing the Right Wire Gauge and Type

Selecting the proper wire gauge (thickness) and composition is imperative to any home wiring project:

• Know your amperage needs - Calculate the amperage draw of the circuit to determine the required wire gauge per code.

• Copper vs. aluminum - Copper is preferred for most household wiring. Aluminum requires special precautions.

• Match wire insulation - Insulation like THHN/THWN is approved for indoor wiring. Use UV-rated insulation outdoors.

• Never undersize wires - Undersized wires overheat quickly. Oversizing is safer.

• Use color codes - Different color insulation denotes hot, neutral and ground wires. Keep color codes consistent.

• Purchase quality materials - Buy wiring from reputable electrical supply stores, not the bargain bin.

For any wiring project, consult local building codes to determine the proper wire gauge and type sanctioned in your area. Using subpar or unsuitable wire can lead to catastrophic failures.

Essential Electrical Tools for Home Wiring

These basic tools will get you through most standard home wiring jobs:

• Voltage tester - A non-contact tester detects live power. Verify electricity is OFF before working.

• Multimeter - Measures voltage, current and resistance to troubleshoot circuits and trace wires.

• Wire strippers - Quickly strips insulation off wire ends. Use the right size for your wire gauge.

• Cable ripper - Safely splits the outer sheathing off Romex and other flexible cable.

• Linesman pliers - Twists wires together, cuts and shapes wire, and drives staples into studs.

• Wire cutters - Cleanly cuts and prepares the ends of wires for connections.

• Screwdrivers - Posi or flat head for installing receptacles, switches, breakers and terminal screws.

• Fish tape - Flexible steel tape for pulling cables through walls and ceilings.

• Headlamp - Frees up both hands and illuminates work area.

Invest in commercial grade tools, not the cheap versions prone to breaking. And learn how to use them properly before wiring.

Wiring a Room from Scratch

Wiring a new room in your home may seem intimidating but can be accomplished with proper planning and execution:

Step 1) Plan the room layout - Decide where you want switches, lights and receptacles located. Include potential future needs too.

Step 2) Shut off main breaker - Locate the main breaker panel and shut off power to the entire house. Test that power is OFF with a voltage tester.

Step 3) Run cable - Notch studs and drill holes to run 14/2 NM Romex cable between the new room and breaker panel. Avoid plumbing.

Step 4) Mount electrical boxes - Secure outlet, switch and junction boxes in the planned locations. Mind code spacing requirements.

Step 5) Pull cables - Use fish tape to carefully pull the cables through holes/notches into boxes. Provide several feet of slack.

Step 6) Connect switches and receptacles - Join hot, neutral and ground wires to devices with proper splices and terminal screws.

Step 7) Install fixtures - Connect light fixtures to wiring and mount them to junction boxes per included instructions.

Step 8) Label breakers - Identify and label which breakers control the newly wired room at the panel.

Step 9) Inspection and power - Call for inspection. Pending approval, turn power back on and test all fixtures and outlets.

Take it slow and steady. Rushing leads to mistakes with potentially hazardous results. If at any point you feel unsure, consult an electrician. Safety first.

Common Electrical Hazards to Avoid

Any mistakes with household electrical wiring can injure, kill or start fires. Here are some of the most common hazards to steer clear of:

• Overloaded circuits - Trying to draw more amperage than the circuit capacity can lead to dangerous overheating.

• Incorrect wire gauge - Undersized wires overheat quickly. Oversized wires waste money. Use the proper size.

• **Faulty grounding ** - Improper or missing ground connections jeopardize safety mechanisms. They are critical.

• Unsecured cables - Loose cables strain connections which heat up and degrade over time. Anchor properly.

• Pierced cables - Nails or screws through cables can immediately arc and spark or slowly damage insulation. Keep clear.

• Reverse polarity - Accidentally swapping hot and neutral creates an electrocution risk and can damage appliances.

• Uncovered junctions - Exposed splices and terminals create a fire and shock hazard if accidentally touched. Keep covered.

• Damaged insulation - Compromised wire insulation exposes dangerous conductive wire. Replace any damaged cable.

Pay close attention to detail, double check everything, and consult local codes to prevent these hazards. Safety first!

When to Call a Licensed Electrician

While many wiring projects can be DIYed, some are best left to licensed professionals:

• Main electrical panel - Only electricians should install, upgrade or repair the main panel and service entrance.

• Heavy appliances - Hardwired stoves, dryers, A/C units, hot tubs etc should be wired by experienced pros.

• New circuits - Licensed electricians are qualified to safely size and install new breaker circuits.

• Whole house rewiring - Rewiring an entire outdated home electrical system is an enormous job requiring pro skills.

• Aluminum wiring - Special techniques are required to safely handle aluminum. Consult an electrician.

• Codes and permits - Electricians know all the codes and can acquire the proper permits from the city.

• Unsure about any task - If at any point you are not 100% confident in doing a wiring job safely, call a pro.

While wiring projects can seem intimidating, safety should be the number one concern. Knowing when to call a licensed electrician is an important wiring skill as well.
