Frequently Asked Questions

 A fuse blows once and must be replaced; a circuit breaker trips and can simply be reset. Breakers are safer and more convenient, which is why modern homes use them.

 A GFCI outlet instantly shuts off power if it detects current leaking (like into water) to prevent shocks. They are required in bathrooms, kitchens, garages, and outdoors.

An AFCI detects dangerous electrical arcs (which can start fires) and trips the breaker. Regular breakers only protect against overloads and short circuits.

 The third prong is the ground wire that safely directs stray electricity away from you. Two-prong outlets/plugs are ungrounded and less safe.

A short circuit happens when electricity takes an unintended path (usually wire-to-wire), causing a sudden surge that trips the breaker or blows a fuse.

Electric current (measured in amperes or amps).

What is overlamping and why is it dangerous?

Junction boxes without covers expose live wires. They must always have a proper cover installed.

Outlets with built-in shutters that only open when both prongs are inserted together — great for child safety and required in new construction.

Used in the 1960s–70s; it expands/contracts more than copper and can loosen connections, creating fire hazards. Special repairs or rewiring are often needed.

Early 1900s–1940s wiring with porcelain knobs and tubes. It lacks grounding and insulation degrades — replace during major renovations or if insuring the home is difficult.

Usually overload (too many devices), a short circuit, or a ground fault. Repeated tripping needs professional diagnosis.

Yes, once or twice is fine if you unplug some devices first. If it keeps tripping, call an electrician.

Overloading, short circuits, ground faults, or faulty appliances. Spread high-power devices across different circuits and avoid cheap extension cords.

Tripped breaker = switch flipped to “OFF” or middle position (can be reset). Blown fuse = melted metal inside (must be replaced).

That appliance draws more power than the circuit can handle. It may need its own dedicated circuit.

If your home is over 40 years old, has only 60–100 amps, or you’re adding major appliances/EV charging — upgrade to at least 200 amps.

Brief small spark is normal (arc when contacts touch), but bright or repeated sparks mean loose wiring — call an electrician.

The outlet contacts have worn out and lost tension. The outlet needs replacement.

Press the “RESET” button on the GFCI outlet. If it won’t reset or trips immediately, the outlet or appliance may be faulty.

Dangerous sign of overloading or loose connections. Unplug everything and call an electrician right away.

Push the “RESET” button firmly. If it won’t stay in, there’s a fault that needs professional attention.

Older 15-amp circuits can’t handle today’s high-draw electronics. Upgrading to 20-amp circuits or adding dedicated lines solves it.

Loose wiring, water damage, or worn contacts. Never ignore — have them inspected.

Not required, but very convenient for charging phones/tablets without adapters.

Ground pin on top is common for commercial/safety reasons. It’s not wrong either way and doesn’t need fixing unless you prefer it flipped.

Loose bulb, loose wiring, voltage fluctuation, or overloaded circuit. Persistent flickering needs professional checking.

Vibration, overlamping, poor-quality bulbs, or voltage issues. Switching to LEDs usually solves it.

Loose service drop from utility pole or tree branches touching lines — contact your power company first.

Incompatible dimmer switch. Use LED-rated dimmers or non-dimmable LEDs.

Turn off breaker, test with voltage tester, follow instructions. If wiring looks old or confusing, call a pro.

Utility power fluctuations or lightning surges. A whole-house surge protector helps.

Only if the bulbs are dimmable (most LEDs now are, but check the package).

Lightning, utility switching, or large appliances cycling. Whole-house surge protectors + good power strips offer best protection.

Usually a loose connection or tripped breaker in that circuit. Needs electrician diagnosis.

Check breaker panel first. If some areas work and others don’t, it’s almost always a tripped breaker or loose wire inside the house.

Installed at the main panel; protects everything from large surges. Highly recommended with expensive electronics and EV chargers.

Every 3–5 years for homes under 40 years old; every year if over 40 or signs of issues.

Frequent breaker trips, flickering lights, warm outlets, burning smells, aluminum wiring, or two-prong outlets.

Adding central AC, EV charger, hot tub, solar, if you have a 60–100 amp service, or if you have an old Federal Pacific Panel.

Too many wires crammed into one spot — causes overheating and is a code violation.

You’re constantly using extension cords or power strips for normal daily use.

Connections loosen over time, overheat, and can cause fires. Needs pigtailing or full rewiring.

Minor tasks like changing a light bulb or cover plate are fine. Anything involving wiring, breakers, or panels should be done by a licensed electrician.

Anytime you have to open the breaker panel, add circuits, or see signs of burning/loose wiring.

Shock, electrocution, fire, voided home insurance, and failed inspections.

Don’t overload circuits, replace damaged cords, install AFCIs/GFCIs, and schedule periodic inspections.

Unplug everything, turn off breaker if possible, and call an electrician immediately — do NOT use that outlet again.

No — they’re temporary only. Permanent use is a fire hazard.

You must still follow the National Electrical Code (NEC) and local amendments; permits and inspections are usually required.

Heating/cooling (50%+), water heater, refrigerator, washer/dryer, and lighting.

Switch to LED bulbs, upgrade old appliances, add smart thermostats, and seal air leaks.

Old inefficient appliances, poor insulation, vampire loads (devices on standby), or electrical leaks. If you have a 3rd party electricity provider check and see if your contract has ended, often times after the contract period they make you pay premium rates, shop around on Power to Choose  to get the lowest rates if necessary.

Yes, but you’ll likely need a panel upgrade, proper inverter, and permits.

Level 2 chargers require a dedicated 240V circuit (usually 40–50 amps) installed by a licensed electrician.

Tripped GFCI or breaker, bad breaker, loose plug, internal failure, or power surge damage.

A break in the wiring path so electricity can’t flow — acts like an “off” switch.

Overload or internal short. Replace with exact same amp rating.

Brushes wear down over time causing sparking or no operation (common in older vacuums, drills, etc.).

Use a multimeter to check continuity when switched on/off. Replace if no continuity in “on” position.

Should be infinite resistance (open). Any reading means insulation failure — motor is unsafe.

Move devices to other circuits or have new circuits added.

Loose connections, corroded wires, or backstabbed outlets failing over time.

Usually because the circuit is too small or shared with other loads. Needs a dedicated 50-amp circuit minimum.

Loose wiring, incompatible LED bulbs, or worn switch. Tighten screws or replace switch.

Start at the breaker panel → outlets → fixtures. Anything beyond resetting breakers or tightening screws should be handled by a pro.

Safety device that cuts power if the appliance overheats. Usually means blocked vents or failing motor — often requires replacement part.

Turn off power, use a non-contact voltage tester, check connections, test continuity with multimeter. Process of elimination.

Home over 40 years old, major renovation, buying/selling, frequent issues, or insurance requires it.

In most areas yes (with permits and inspections), but it must pass code and many insurers dislike DIY electrical.

Ammeter or clamp meter (multimeters can do it too).

Use dimmable LEDs with LED-compatible dimmers; remove ballasts in fluorescent fixtures if necessary.

Undersized panels, ungrounded outlets, cloth-insulated wiring, aluminum wiring, and lack of GFCI/AFCI protection.

Smart switches/dimmers often require neutral wires that older homes lack, plus proper load rating and Wi-Fi stability.

Overheating wires, melting insulation, or arcing — shut off power and call an electrician immediately.

Schedule a full electrical inspection with a licensed electrician — we’ll give you a detailed report and fix any violations.
