Common Electrical Questions
If something feels off, tap a question below. And if it's not here, call us and we'll talk it through.
My outlet sparked and smells like burning. What do I do right now?
Stop using the outlet and keep away from it. For smoke, fire, or a suspected active fire, leave and call 911 from a safe place. Do not touch damaged equipment or approach a hot or sparking panel; arrange electrical assessment once the immediate danger is addressed.
Why does my breaker keep tripping even after I reset it?
Repeated tripping can result from excess demand, a wiring fault, connected equipment, or the breaker itself. Leave a repeatedly tripping circuit off and have the cause checked. Do not keep resetting or force the breaker.
Half my house lost power but no breaker tripped. What's wrong?
Partial power loss can originate in the building or the utility supply. The symptom alone does not prove a loose connection in the neutral wire that returns current or identify which equipment failed. Contact the serving utility about an outage and arrange electrical assessment as needed; avoid damaged equipment.
Are flickering lights throughout the house dangerous?
Persistent flicker in several areas warrants prompt assessment. It can have more than one cause, including building wiring or the utility supply. Keep clear of any hot, damaged, or sparking electrical equipment.
I have a Federal Pacific or Zinsco panel. Is it really a fire hazard?
The brand name alone does not establish the condition of your panel. Identify the exact equipment and have accessible components assessed. We can explain replacement options and the limits of what an inspection can establish.
When is an electrical problem an emergency vs. something that can wait?
Smoke, fire, or an immediate threat to people requires emergency services. Stay away from exposed, damaged, or wet electrical equipment. Repeated tripping, new heat, smell, or unusual noise needs prompt assessment; a short online description cannot establish that it is safe to wait.

Electrical Questions, Answered
Answers to common electrical questions for homes and businesses. For advice about your property, tell us the location and what you want to repair or install.
Breakers & Tripping 3
My breaker won't reset. Is that an emergency?
Leave the breaker off and arrange an electrical assessment. The symptom alone does not identify the cause, and forcing or repeatedly resetting it is not a repair. Smoke, fire, or an immediate threat calls for 911 from a safe location.
Why does my AFCI / arc-fault breaker keep tripping for no reason?
An arc-fault circuit interrupter (AFCI) detects certain unintended electrical arcs, which are discharges across a gap. Repeated trips can involve wiring, a connected device, or the protective equipment. Diagnosis should establish the cause before anything is replaced or bypassed.
Why can't I just replace my breaker with a bigger one?
The breaker must suit the wiring and equipment it protects. Increasing its rating without checking the entire circuit can leave wiring inadequately protected. We assess demand and the circuit before recommending changes.
Outlets, Sparks & Safety 5
There are black scorch marks around my outlet. Is it dangerous?
Scorching or melting needs prompt electrical assessment. Stop using the outlet; replacing its faceplate or device alone may leave the underlying cause unresolved. Do not open or touch damaged equipment.
My outlet is warm or hot to the touch. Is that normal?
Unusual heat, discoloration, smell, or damage warrants an assessment. Stop using a hot outlet. The symptom does not establish whether the cause is the outlet, a connection, or connected equipment.
Half my outlets stopped working but the breaker isn't tripped. Why?
Several faults can produce that symptom, including loss of supply or a protective device elsewhere on the circuit. We trace the affected circuit before recommending a repair; the symptom alone does not identify a failed connection.
Why won't my GFCI outlet reset?
A ground-fault circuit interrupter (GFCI) helps protect against electric shock. It may not reset because power is absent, a fault remains, or the device needs attention. Leave it out of use and have the cause checked rather than repeatedly resetting it.
My outdoor or bathroom GFCI keeps tripping when it rains. How do I fix it?
Moisture may be involved, but the affected wiring and equipment need assessment. Stop using the affected equipment and avoid wet electrical areas. Do not bypass the protection or assume a new cover alone fixes the problem.
Electrical Panel Upgrades 6
What are the signs I need to upgrade my electrical panel?
New equipment, a damaged panel, or limited circuit space are reasons to assess the system. Repeated tripping needs diagnosis rather than an automatic upgrade. A load calculation, an assessment of electrical demand, helps determine whether more supply capacity is needed.
Is upgrading from 100 amp to 200 amp worth it?
It depends on the existing supply, equipment condition, and planned demand. The service is the utility power supply to the home; increasing it differs from adding circuit space. We compare the options with your plans before recommending a size.
How much does a 200 amp panel upgrade cost in the Bay Area?
The existing panel, meter arrangement, cable route, and utility requirements all affect cost. A site review helps separate panel work from a utility supply change and other necessary work. Ask us to assess the scope before comparing prices.
My panel is full with no breaker spaces left. What are my options?
First separate circuit space from available electrical capacity. A subpanel, a secondary panel supplied from another panel, can add spaces but does not increase the utility supply. Other options depend on the manufacturer-approved equipment configurations and a demand assessment.
How long does PG&E take to approve a service upgrade?
Utility review and on-site installation follow different schedules. The existing supply, proposed demand, equipment, and permit path affect the process. Check the current project schedule with the serving utility after the scope is established.
Why is an underground service upgrade so much more expensive than overhead?
Underground work can involve excavation, protective tubing for cables, access, and surface restoration. The actual utility design determines what is needed. Compare itemized scopes rather than assuming every underground project has the same costs.
Old Panels & Wiring 5
Will my insurance drop me because of my old panel or wiring?
Coverage decisions belong to your insurer. Ask for its written equipment or inspection requirements, then share those with us. An electrical assessment can document findings and repair options without guaranteeing insurance acceptance.
Is knob-and-tube wiring safe, and will insurance cover my house?
Knob-and-tube is an older wiring method that uses separate conductors supported by ceramic parts. Its condition and any later modifications need assessment. Ask your insurer separately about its requirements; a webpage cannot determine coverage or the condition of concealed wiring.
Is aluminum wiring a fire risk, and can I still get insured?
The wiring type, connections, and condition need to be identified before recommending repairs. Aluminum wiring requires compatible connection methods and equipment. Insurance acceptance is a separate question for your carrier.
I have two-prong ungrounded outlets. How do I add grounding?
A protective grounding connection helps carry current from an electrical fault back to its source. A three-slot outlet alone does not establish that path. We assess the existing wiring and applicable replacement options; shock protection and an equipment ground are different features.
How much does it cost to rewire an old house?
Cost depends on the wiring to replace, access, circuits, finishes, and any associated panel work. We assess the conditions and discuss whether the work can be phased. Wall repair and painting should be identified separately.
EV Charger Installation 5
Does my home panel have enough amps for a Tesla or Level 2 charger?
The charger setting, existing demand, and equipment ratings determine what is possible. A load calculation assesses demand, while compatible load management limits charging power when necessary. We review both before recommending a supply upgrade.
How much does it cost to install a home EV charger in California?
Cable length, access, charger requirements, and available capacity affect the price. Photos can help plan an assessment but may not establish concealed conditions. Ask for a scope that distinguishes equipment, electrical work, and other site work.
Do I need a panel upgrade just to add an EV charger?
Not always. We compare the charging requirement with existing demand and equipment ratings. A lower charging setting or compatible power management may be an option, but the assessment must establish whether it meets your needs.
Can I install an EV charger if my panel is already maxed out?
First establish whether the limit is circuit space, electrical capacity, or equipment condition. A secondary panel adds spaces but does not create supply capacity. We assess charging limits, compatible controls, and any required supply change separately.
Are there rebates or tax credits for home EV charger installation?
Check current eligibility and application timing with the program administrator before budgeting an incentive. A special electricity rate is different from an installation rebate. Equipment, location, and funding conditions can change.
Flickering & Power Loss 2
Why do my lights flicker or dim when the AC or an appliance turns on?
Starting equipment can affect voltage, but the pattern and severity need assessment. Note which lights change and what equipment is operating. New, persistent, or worsening flicker should be checked rather than attributed to one cause from the symptom alone.
Is the buzzing or humming sound from my electrical panel normal?
New or pronounced buzzing or crackling needs assessment, especially with heat, smell, or visible damage. Do not remove the panel cover. For smoke, fire, or an immediate threat, leave and call 911 from a safe location.
Lighting & Switches 3
Why is my dimmer or light switch warm or hot to the touch?
Some dimmers produce warmth in normal use, but unusual heat or damage should be checked against the device instructions and connected lighting. Stop using a hot or discolored control and arrange assessment; do not open it yourself.
How much does it cost to install recessed lighting with no attic access?
Access, fixture choice, wiring routes, and finish repairs affect the cost. We review the ceiling and explain likely openings before pricing. Limited access does not support a blanket promise of no drywall damage.
Do I need an electrician to install a ceiling fan where there's no wiring?
A new fan location needs suitable wiring and support rated for the selected fan. We assess the route, mounting, and controls before defining the installation. Do not assume an existing light box can support a fan.
Permits & Code (California) 4
Do I need a permit for electrical work in California?
Permit requirements depend on the work and local jurisdiction. Identify the scope and confirm the permit path with the building department before construction. Our electrical scope should state who handles applications and inspections.
What happens if electrical work was done without a permit?
Start with available plans, records, and the building department requirements. The authority may request documentation or access to review the work. Insurance and property-transaction consequences depend on the circumstances and should not be assumed.
Does my ADU need a separate electrical meter or panel in California?
An accessory dwelling unit (ADU) needs an electrical design suited to the property and proposed demand. Metering and panel arrangements depend on local and utility requirements and the project design. Confirm them before selecting equipment.
What is Title 24 and how do I make my lighting comply?
Title 24 is the California Building Standards Code; Part 6 contains the Energy Code. The applicable lighting requirements depend on the project. Agree with the design and permit team on who selects fixtures and controls, prepares documentation, and performs any required testing.
Electrical Emergencies 2
I smell electrical burning but can't find the source. What do I do?
If you suspect an active fire, leave the area and call 911 from a safe location. Do not search inside electrical equipment or approach a hot or sparking panel. A burning smell needs prompt professional assessment even when its source is unclear.
Who do I call for a power emergency, the electrician or PG&E?
Call 911 for a downed power line or an immediate threat, and keep clear. Report utility outages to the serving utility. An electrician can assess customer-owned equipment, but ownership and the fault location may need investigation.
Pricing & Hiring 3
Why are electrician quotes so different? How do I compare them?
Compare the actual work, materials, access assumptions, permit responsibilities, testing, finish repairs, and exclusions. Check how changes are priced. A price difference alone does not show that another contractor is omitting necessary work.
How do I check that an electrician is licensed (CSLB lookup)?
Use the California Contractors State License Board (CSLB) lookup and compare the listed business, classification, and status with the contracting documents. Our site lists license #1145945; the official record is the place to verify current details.
Do you offer a warranty on your work?
Ask for the written workmanship and equipment terms for your project before work begins. Coverage, exclusions, maintenance conditions, and who provides service should be clear; do not assume all projects have the same warranty.
Backup Power & Surge 3
How much does a whole-house generator with transfer switch cost?
Generator size, supported equipment, transfer arrangement, fuel work, placement, and local approvals affect cost. A transfer switch changes the supply between utility and generator power. Review all of those items before comparing installation quotes.
Can a smart panel or backup battery replace a full panel upgrade?
Controls that limit electrical demand may change the options, but a battery or smart panel does not automatically increase the utility supply. Assess the equipment, demand, and backup goals together before deciding whether a panel or supply upgrade is needed.
What is whole-home surge protection and do I need it?
A surge protective device limits certain brief increases in voltage. It cannot prevent every type of electrical damage or correct a wiring fault. Review the equipment, installation requirements, and protection limits before choosing a device.
