When to Call a Licensed Electrician
If you have worked through the earlier steps in this checklist and the electrical problem persists—or if the issue involves your panel, wiring, or anything that makes you uncomfortable—it is time to call a licensed electrician. Electrical work is one area where the consequences of mistakes are severe: shock, fire, and code violations that void your insurance. This guide helps you draw a clear line between safe DIY fixes and jobs that genuinely need a professional.

Always Call a Licensed Electrician For These Issues
The following situations require a licensed electrician. Do not attempt these yourself:
- Any work inside the electrical panel: Breaker replacements, bus bar connections, main breaker work, and panel upgrades involve live conductors at full service amperage. Arc flash can cause severe burns and death.
- Adding new circuits: Running new wire, adding breakers, and connecting circuits to the panel requires load calculations, code knowledge, and a permit in virtually every jurisdiction.
- Aluminum wiring issues: Homes built between 1965 and 1973 may have aluminum branch wiring, which expands and contracts differently than copper and is a documented fire hazard. Special COPALUM or AlumiConn connectors are required—standard wire nuts are not safe.
- Burning smell from outlets or panel: A burning or melting plastic smell indicates arcing, overheating, or melting insulation. Turn off the circuit at the panel immediately and call an electrician. This is a fire in progress or about to start.
- Repeated breaker trips on the same circuit: A breaker that trips more than twice in a row after resetting is telling you something is wrong—a short circuit, ground fault, or overloaded wiring. Forcing it to stay on by holding the breaker or upsizing the breaker is extremely dangerous.
- Any work requiring a permit: New circuits, panel upgrades, service changes, and major alterations require permits and inspections. Unpermitted electrical work can void your homeowner's insurance and create serious legal liability when selling.
When Permits Are Required
Permit requirements vary by jurisdiction, but this general breakdown applies in most areas of the United States and Canada:
Permit usually NOT required
Replacing outlets, switches, light fixtures, ceiling fans (on existing boxes), and smoke detectors on existing circuits. Essentially, like-for-like replacements that do not alter the wiring or circuit.
Permit usually required
Adding new outlets or circuits, panel upgrades or replacements, installing sub-panels, running new wiring through walls, converting from fuses to breakers, adding dedicated circuits for appliances, and any work involving the service entrance.
Why it matters
Unpermitted electrical work is the number one reason home insurance claims get denied after electrical fires. It also creates disclosure problems when selling your home and can result in fines from your local building department. The permit itself typically costs $50 to $200—a small price for legal protection.
Aluminum Wiring: A Special Case
If your home was built between 1965 and 1973, there is a significant chance it has aluminum branch circuit wiring. This is not a DIY situation.
- The problem: Aluminum expands and contracts more than copper when heated, causing connections to loosen over time. Loose connections create heat, and heat creates fire. CPSC data shows homes with aluminum wiring are 55 times more likely to have fire-hazard conditions.
- How to identify it: Look at the wiring entering your panel or at an outlet. Aluminum wire is silver-colored (copper is orange). The cable jacket may also be stamped "AL" or "ALUMINUM."
- The fix: A licensed electrician can install COPALUM or AlumiConn connectors at every connection point—outlets, switches, fixtures, and the panel. This is called "pigtailing" and typically costs $50 to $75 per connection point. A whole-house remediation runs $2,000 to $5,000 depending on the number of connections.
- What NOT to do: Never use standard twist-on wire nuts to connect aluminum to copper. Never ignore discolored cover plates, flickering lights, or warm outlets in a home with aluminum wiring—these are warning signs of overheating connections.
Emergency vs. Scheduled Service
Understanding the difference can save you significant money. Emergency electricians charge 50 to 100 percent more than standard rates.
- True emergencies (call now, any hour): Burning smell from a panel or outlet, sparking that will not stop, complete loss of power to the home (after confirming it is not a utility outage), exposed live wires from storm damage, or flooding near the electrical panel.
- Urgent but not emergency (call first thing in the morning): A circuit that trips and will not reset, a single room that has lost power, a GFCI outlet that will not reset, or light switches that feel warm to the touch.
- Schedule at your convenience: Adding outlets in a room, upgrading two-prong outlets to three-prong, installing dimmer switches, adding dedicated circuits for new appliances, and annual electrical inspections.
Electrical Work Most Homeowners Can Do Safely
If the breaker is OFF and confirmed dead with a voltage tester, these tasks are generally safe for a careful homeowner. Always check local codes first.
- Replace a light switch: Turn off the breaker, confirm power is off with a non-contact voltage tester, swap the switch, and restore power.
- Replace a standard outlet: Same process as a switch. Match wire-to-terminal connections exactly as the old outlet was wired.
- Replace a light fixture: Support the fixture, match wire colors (black to black, white to white, green/bare to ground), and secure with wire nuts.
- Replace a GFCI outlet: Follow the LINE and LOAD terminal markings carefully. Incorrect wiring will prevent the GFCI from protecting downstream outlets.
- Reset a tripped breaker: Flip fully OFF, wait 30 seconds, then flip ON. If it trips again immediately, stop and call an electrician.
- Replace smoke detector batteries: Test monthly, replace batteries annually, replace the entire unit every 10 years.
Pro Tips
- •Verify the license: Ask for the electrician's license number and verify it with your state or local licensing board online. A licensed electrician carries liability insurance and pulls permits—an unlicensed handyman typically does neither.
- •Get the permit yourself if needed: In many jurisdictions, homeowners can pull their own electrical permits. This lets you hire the electrician you want while still getting the work inspected by the building department.
- •Take photos before and after: Photograph the inside of every box before the electrician starts and after the work is done. This creates a record of what was changed and helps future electricians understand the wiring.
- •Never upsize a breaker to stop trips: If a 15-amp breaker keeps tripping, replacing it with a 20-amp breaker does not fix the problem—it removes the protection. The wire is rated for 15 amps, and forcing 20 amps through it can melt the insulation and start a fire inside your walls.
Frequently Asked Questions
What electrical work requires a licensed electrician?
Any work inside the electrical panel, adding new circuits, upgrading service capacity, working with aluminum wiring, installing sub-panels, and any job that requires a permit must be done by a licensed electrician. Simple device replacements like switches and outlets on existing circuits are generally homeowner-safe in most jurisdictions, but panel work and new wiring are not.
How much does an electrician charge for a service call?
A typical electrician service call costs $75 to $150 for the trip and initial diagnosis. Hourly rates range from $50 to $100 for standard work and $100 to $150 or more for master electricians. Emergency and after-hours calls can cost $150 to $300 or more. Many electricians offer flat-rate pricing for common jobs like outlet or switch replacements.
Is it illegal to do your own electrical work?
Laws vary by jurisdiction. Most areas allow homeowners to perform basic electrical work on their own primary residence, such as replacing outlets, switches, and light fixtures. However, work that requires a permit—new circuits, panel modifications, and major alterations—typically must be done by or inspected by a licensed professional. Doing unpermitted work can void your homeowner's insurance and create issues when selling your home.
