From troubleshooting tripped breakers to upgrading outdated panels and installing modern safety devices, our electricians handle the electrical needs that matter most to local families.
The FAQs below address the most common electrical questions we hear from homeowners in Northern Utah, including concerns about flickering lights, GFCI outlets, panel upgrades, wiring safety, and surge protection.
Why do my lights dim when I turn on large appliances?
When your lights flicker or dim as your air conditioner kicks on or your hair dryer starts running, you are seeing the effects of voltage drop under heavy electrical load. Large appliances can draw 3,000 to 5,000 watts on startup, creating temporary strain on circuits designed for much smaller loads.
In many Utah homes built before the 1980s, electrical systems were sized for far fewer appliances than families use today. A 100-amp electrical panel that once seemed adequate now struggles against modern demands from multiple televisions, computers, kitchen appliances, and HVAC equipment all running on the same circuit.
Occasional brief dimming during appliance startup is common, but persistent or severe dimming indicates your electrical system cannot safely handle your household load. This often points to undersized wiring, loose connections, or an overloaded panel that needs professional evaluation.
Solutions typically include upgrading to a 200-amp panel, installing dedicated circuits for high-draw appliances, or addressing wiring issues that restrict electricity flows throughout your home.
What causes my GFCI outlets to keep tripping?
A ground fault circuit interrupter, commonly called a GFCI outlet, monitors electrical current flowing through the circuit and instantly cuts power when it detects an imbalance as small as 5 milliamps. This rapid response protects against electrical shock in areas where water and electricity might meet.
Common causes of repeated GFCI tripping include moisture infiltration, faulty appliances with damaged wires, worn outlets, or wiring issues elsewhere on the circuit. In Utah homes, basement moisture and outdoor weather exposure frequently trigger nuisance trips, especially during spring snowmelt or summer thunderstorms.
Before calling an electrician, try these troubleshooting steps: unplug all devices from the circuit, press the reset button firmly, and plug items back one at a time to identify a faulty appliance. Check that outdoor outlets have weatherproof covers properly installed.
If your GFCI outlet continues tripping after basic troubleshooting, or if you notice visible damage, burning smells, or outlets that feel warm, contact a licensed electrician. The fault circuit interrupter may be worn out, or you could have wiring problems requiring professional diagnosis.
How do I know if my electrical panel needs upgrading?
Your electrical panel serves as the central hub distributing power throughout your home. Signs that your panel needs attention include frequent circuit breaker trips, a breaker that will not stay reset, burning smells near the panel, visible rust or corrosion, or a panel still using fuses rather than modern breakers.
Many Ogden and Salt Lake City homes built in the 1970s and 1980s contain panels from manufacturers later identified as safety concerns. If your panel shows signs of age or you experience repeated electrical issues, having a licensed electrician inspect your system can identify problems before they become dangerous.
Modern electrical demands far exceed what older 100-amp panels were designed to handle. Today’s households often need 200-amp service to support multiple high-draw appliances, electric vehicle charging, home offices, and HVAC systems without overloaded circuits.
Upgrading your electrical panel improves safety, supports additional circuits for remodels or new appliances, and can increase home value by 5 to 10 percent. Many insurance companies also require panel upgrades in older homes to maintain coverage.
Is knob and tube wiring dangerous in my older Utah home?
Knob and tube wiring was standard in homes built before the 1950s and consists of individual hot wire and neutral conductors run through ceramic insulators. While this wiring was safe when installed, decades of use, modifications, and insulation blown over the wires have created significant fire risks.
The primary concerns include deteriorated insulation that exposes bare wire, connections that were never designed for modern electrical loads, and the heat buildup that occurs when attic insulation covers these old circuits. Unlike modern electrical wiring with grounding protection, knob and tube provides no path to safely redirect fault current.
Insurance implications are substantial. Many Utah insurers deny coverage or charge significant premiums for homes with active knob and tube wiring. Selling a home with this wiring type often requires either rewiring or substantial price reductions.
Complete rewiring is the safest solution, though the process varies based on home size and accessibility. Most homeowners can remain in the house during rewiring, with professionals working section by section to minimize disruption while bringing the electrical system up to current code requirements.
Why do some outlets in my home not work?
Dead outlets frustrate most homeowners, but the cause is often simpler than expected. Start by checking whether a GFCI outlet elsewhere controls the dead outlet. GFCI protection extends to other outlets on the same circuit, so a tripped GFCI in your bathroom might cut power to outlets in adjacent rooms.
Next, check your electrical panel for a tripped breaker. A circuit breaker trips by moving to a middle position between on and off. To reset a tripped breaker, push it firmly to the off position first, then back to on.
If the GFCI reset button and circuit breakers check out, the problem likely involves loose connections at the outlet itself, damaged wires in the wall, or a failed outlet that needs replacement. These conditions require professional diagnosis because working with electrical wiring while power is present creates serious shock hazards.
Never attempt to remove outlet covers or touch wiring without first shutting off power at the breaker and verifying the circuit is dead with a voltage tester. When in doubt, having a professional handle electrical outlet troubleshooting ensures your safety.
Do I need surge protection for my Salt Lake City area home?
Utah’s summer thunderstorms bring lightning that can send voltage spikes up to 6,000 volts through power lines, potentially destroying electronics and appliances in seconds. A single lightning strike near power infrastructure can damage computers, televisions, HVAC controls, and other sensitive equipment throughout your home.
Point-of-use surge protectors, the power strips many homeowners rely on, typically handle only 1,000 to 2,000 joules of surge energy. Whole-home surge protection installed at your electrical panel handles 20,000 to 60,000 joules, diverting 99 percent of power surges before they reach your devices.
Beyond lightning, power surges occur daily from utility fluctuations, nearby industrial equipment, and even appliances cycling on and off within your own home. These smaller surges gradually degrade electronics over time, shortening their lifespan.
Whole-home surge protection typically costs $300 to $800 installed and works alongside plug-in protectors to provide layered defense. Given the investment most Utah families have in computers, smart home systems, and modern appliances, surge protection offers significant value in prevented damage.
What electrical permits do I need for home improvements in Utah?
Electrical permits are required in Layton, Ogden, Salt Lake City, and throughout Utah for most electrical work beyond simple fixture replacements. Projects requiring permits include panel upgrades, new circuit installation, outlet additions, and any work involving your home’s permanent wiring.
Permit requirements exist to ensure electrical work meets the National Electrical Code, which Utah has adopted to protect homeowners from electrical fires and shock hazards. Work performed without permits can void insurance coverage, complicate home sales, and create serious safety risks.
Unpermitted electrical work discovered during a home inspection often requires tearing out completed projects for proper inspection, costing homeowners thousands in repeated work. Some insurance companies deny claims for damage caused by unpermitted electrical modifications.
When you hire Mountain Home Services, our licensed electricians handle the entire permit process, from application through final inspection. This ensures your electrical project meets all local requirements and protects your investment in your home.
Can I install a ceiling fan where I currently have a light fixture?
Installing a ceiling fan where a light fixture currently hangs is possible, but requires attention to the electrical box supporting the fixture. Standard light boxes support only 15 to 25 pounds, while ceiling fans weigh 25 to 50 pounds and create rotational forces that can pull a standard box loose over time.
Ceiling fan installation requires a properly braced electrical box rated for fan support, either attached directly to a ceiling joist or secured with an expandable brace between joists. If your existing box is not fan-rated, it must be replaced before installation.
Wiring considerations depend on your desired controls. A simple single-switch setup can often use existing wiring, but separate fan and light controls require additional wiring between the switch location and the ceiling. Many homeowners opt for smart switches or remote controls that provide full functionality without rewiring.
For two-story homes or installations where attic access is limited, professional installation ensures the mounting is secure without damaging ceilings or creating safety hazards.
Why does my home’s electrical system make buzzing or crackling sounds?
Electrical sounds demand immediate attention. Buzzing, crackling, or sizzling from outlets, switches, or your electrical panel often indicates loose connections, arcing electricity, or overloaded circuits generating dangerous heat.
Loose connections at outlets or in your electrical panel cause electricity to arc across gaps, generating heat that can ignite surrounding materials. This arcing is a leading cause of electrical fires, responsible for thousands of home fires annually according to the National Fire Protection Association.
Buzzing at a light switch often indicates the switch is failing or is paired with incompatible LED lights that create electrical noise. While less immediately dangerous, failing switches should be replaced to prevent further deterioration.
If you hear crackling or smell burning from any part of your electrical system, shut off power at the main breaker and call a licensed electrician immediately. Do not attempt to investigate or repair arcing electrical connections yourself. These situations represent genuine fire hazards requiring emergency response.
How much does electrical work typically cost in the Utah area?
Electrical service costs vary based on the complexity of work, materials required, accessibility of wiring, and your home’s existing electrical system condition. For perspective, common services in the Layton, Ogden, and Salt Lake City areas typically fall within these ranges:
Outlet or switch replacement runs $75 to $200 per location. Panel upgrades from 100 to 200 amps cost $1,500 to $4,000 depending on your home’s specific requirements. Whole-home surge protection installation averages $300 to $800. GFCI outlet installation in kitchens, bathrooms, and outdoor areas typically costs $100 to $200 per outlet.
The value of quality electrical work extends beyond the immediate fix. Properly installed electrical components last decades, while poor workmanship creates ongoing problems and safety hazards. Code-compliant work protects your insurance coverage and home value.
The most accurate way to understand costs for your specific electrical needs is scheduling an in-home evaluation. Mountain Home Services provides detailed estimates that explain exactly what work is needed and why.
