Installing your own home electrical system can be a rewarding project that saves you money, but it also comes with risks if not done properly. Follow this guide to learn how to safely and legally install basic home electrical components.
Research Local Building Codes and Permit Requirements
The first step is understanding your local jurisdiction's building codes and permit requirements. Electrical work often requires permits to meet minimum safety standards.
-
Contact your local building department to ask about electrical permit requirements in your area. Generally, basic installations like lights, switches and outlets can be done without a permit if you own and live in the home. More complex projects like new circuits usually need permits.
-
Ask the building department if there are exceptions to permit requirements. Some areas waive permits for minor electrical work done by homeowners in their residence.
-
Find out about inspections. Permitted electrical work requires passing inspections at certain stages to verify it meets code.
-
Research local and national electrical codes for your area. The National Electrical Code (NEC) forms the basis of most local codes. Review these to understand legal installation requirements before starting.
Evaluate Your Skills and Project Scope
Be realistic about your electrical skills and only take on what you can safely handle:
-
Electricity can be dangerous. Honestly assess your experience working with electrical systems before tackling installations.
-
Start with simple projects like installing new switches or lights on existing circuits. Leave complicated tasks like new circuits to professionals until you gain more experience.
-
Set a maximum scope for doing your own work. Know when to hire an electrician for more advanced projects. Attempting work beyond your skill level can put you and your home at risk.
Use Extreme Caution and Pay Attention to Safety
Electrical safety should be your top priority. Take every precaution when working with electrical components:
-
Turn off power at the main breaker panel. Verify it's off by testing with a non-contact voltage tester. Lock out the main breaker and tag it "off" as an extra precaution.
-
Disconnect wires safely. Use insulated tools and wear personal protective equipment like gloves and eye protection. Remove only one wire at a time when disconnecting.
-
Connect new wires securely. Use proper connectors and secure wires tightly so connections won't loosen over time.
-
Insulate all connections. Use wire nuts or electrical tape so no conductors are exposed.
-
Keep the work area dry. Don't work in damp areas or use wet tools which can cause shock or fires.
Take Things Slowly with a Methodical Approach
Allow plenty of time so you can move slowly and focus on working safely:
-
Shut off the power well in advance so you have time to verify it's off before starting work.
-
Lay out all necessary tools and materials beforehand so they're ready to go.
-
Follow installation instructions carefully for each component. Don't skip any steps.
-
Double check connections are tight and properly insulated when finished with each wire.
-
Take breaks as needed if you feel tired, distracted or rushed. Electrical work requires full attention.
Have Your Work Inspected Before Turning Power Back On
-
If the project required a permit, call the building department to schedule a final inspection once the installation is complete. They will verify your work meets code requirements.
-
For small unpermitted projects, consider hiring an electrician to inspect the work. They can catch any problems before energizing the system.
-
Correct any issues found during inspections. Only turn the power back on once you receive approval that the system is safe.
Follow Up with Regular Electrical System Maintenance
-
Check that all electrical components are still working properly right after turning the power back on and throughout the following week.
-
Visually inspect wires and connections looking for any damage or loosening over time which could cause hazards. Tighten or repair as needed.
-
Consider having an electrician periodically inspect even minor electrical work to catch any issues early. Electrical safety demands diligence.
Taking the proper precautions makes it possible to safely install your own basic home electrical system. But always put safety first and seek expert help when needed. Remember, electricity should be handled with care, caution and respect.
