FAQ

Two-prong outlets lack a ground, so they’re not as safe as modern three-prong ones. They’re grandfathered into older homes, but upgrading to grounded outlets will make it safer.

Check your panel for tripped breakers, and see if neighbors are affected to rule out a utility issue. If it’s isolated to part of your home or happens frequently, call for help.

It’s not recommended. Paint can get inside the slots or switches and interfere with connections. If you want to change the look, swap the covers with new ones instead.

Yes, outlets can develop loose terminals or internal wear that increases fire risk. If you notice cracking, discoloration, or plugs falling out easily, it’s time for a replacement.

A dedicated circuit powers only one appliance or outlet, like a microwave or EV charger. These are required for heavy-use items to prevent overloads and maintain consistent power.

Older panels sometimes lose labels during past upgrades or repairs. It can be dangerous in an emergency. A professional can map your panel and clearly relabel each breaker.

You’ll need GFCI protection, weatherproof covers, and the correct conduit for underground or exposed wiring. It’s important to use components rated for exterior use to avoid corrosion and water damage.

Yes, fluctuating voltage or improper grounding can wear down components or cause them to fail. If appliances keep breaking or acting strangely, your wiring might be part of the problem.

Tamper-resistant outlets are now required by code in new homes and offer the best protection. Avoid cheap plastic covers that can be pried off. Secure wires and teach safety from a young age.

If it feels warm, smells burnt, or trips the breaker when used, it’s likely overloaded. Running too many devices from one outlet is a fire hazard and should be corrected quickly.

Extension cords are meant for short-term use and can overheat or get damaged over time. For long-term solutions, it’s safer and cleaner to have additional outlets installed where you need them.

The neutral wire completes the circuit by carrying current back to the panel, while the ground wire provides a backup path in case of a fault. They serve different purposes and should never be mixed.

Aluminum wiring can become loose over time, which increases the risk of overheating or fire. It can be retrofitted with special connectors to make it safer, but many homeowners choose to replace it altogether.

Yes, but only with LED-compatible dimmers. Using a standard dimmer can lead to flickering, limited dimming range, or buzzing sounds. Replacing the switch usually solves the issue.

Not in a dramatic way, but older wiring can run less efficiently, especially if there are loose connections or undersized circuits. Over time, that inefficiency adds up in both cost and risk.

An upgraded panel can handle more load safely, which is important if you’re adding high-draw appliances or finishing a basement. It also makes your home more efficient and reduces the risk of overheating or outages.

Permits make sure that the work is inspected and meets safety codes. It protects your property and any future buyers. In some areas, unpermitted work can cause trouble during home sales or insurance claims.

Many are, but it depends on the device and your wiring. Some require a neutral wire or constant power, which older systems may not support. It's always smart to check the specs before installing.

A whole-home surge protector will be installed at your electrical panel and defend your wiring and devices from sudden voltage spikes. They're very useful in storm-prone areas or homes with lots of electronics.

Frequent breaker trips, dimming lights, or outlets that feel warm can all be signs. If your home has aluminum wiring or knob-and-tube systems, it’s definitely time to have it evaluated.

Yes, those areas are considered “wet zones,” and GFCI outlets are required by code to help prevent shock. They cut off power almost instantly when they sense current leaking outside the normal path.

A small blue spark can be normal, especially with high-draw devices. But if it happens regularly, comes with a buzzing sound, or leaves scorch marks, the outlet might be worn out or have loose internal connections.

A grounded system gives excess electricity a safe route into the earth if there’s a fault. This helps protect people, appliances, and the entire system from electric shock or surge-related damage.

While it might seem safe if the power’s off, mistakes in wiring can create long-term risks like fire hazards or electrocution. Many areas also require a licensed electrician for code compliance and inspections.

This usually happens when the AC draws a large amount of current on startup, and temporarily drops the voltage to other circuits. If it happens often or gets worse, it might be because of undersized wiring or a loose connection in the panel.

Every 3 to 5 years is a good baseline for inspections, especially in older homes or properties with recent renovations. Regular checks can catch hidden problems, confirm safe grounding, and keep you compliant with local code.

A breaker panel uses resettable switches to stop the flow of electricity when there’s a problem, while a fuse box relies on fuses that melt and need to be replaced after they blow. Breaker panels are more convenient and safer, which is why they’re standard in modern homes.
