Frequently Asked Questions
What are the signs that my electrical panel is outdated or hazardous?
If your panel is a brand associated with known safety failures, it should be replaced immediately. Other warning signs include burn marks on the bus bars, breakers that fail to trip during an overload, or a persistent "crackling" sound. In 2026, panels over 25 years old are generally considered past their operational prime and may not support modern safety standards.
How long does a full electrical panel replacement take?
A standard residential replacement typically takes 4 to 8 hours. During this time, the main power to your home must be disconnected by the utility company or via the main shut-off. Our team removes the old interior components, installs the new bus bar assembly and breakers, and performs a thorough bonding and grounding check before restoring power.
What is included in a professional electrical panel inspection?
We perform a comprehensive 20-point check, including thermal imaging to detect hidden hotspots, torque-testing all terminal connections, and verifying the integrity of the main grounding electrode. We also check for "double-tapped" breakers and ensure the panel is correctly sized for your home's actual electrical demand based on a current load calculation.
Why is a permit required for replacing an electrical panel?
In almost all jurisdictions, a panel replacement is considered a major structural change to the electrical system. A permit ensures that a city inspector verifies the work meets 2026 National Electrical Code (NEC) safety standards. This documentation is critical for maintaining your homeowner’s insurance coverage and is a requirement during any future home sale.
Will a panel upgrade increase my home’s power capacity?
A panel replacement alone doesn't increase the power coming from the utility, but an "upgrade" (e.g., from 100-amp to 200-amp service) does. This process involves replacing the meter socket and the service entrance cables. This ensures your home can safely support high-draw equipment like EV chargers, heat pumps, and modern kitchen suites.
What is the difference between a main breaker and a sub-panel?
The main breaker panel is the primary point where power enters your home and contains the main shut-off for the entire property. A sub-panel is a smaller distribution board used to provide power to a specific area, such as a garage or a home addition. Sub-panels are excellent for organizing circuits but still rely on the main panel for their total power supply.
Why do I need to move my panel out of the closet or bathroom?
Modern safety codes strictly prohibit electrical panels in bathrooms (due to moisture) or clothes closets (due to combustible materials). If your current panel is in a restricted location, a replacement project is the mandatory time to relocate it to a safe, accessible area with at least 3 feet of clear working space.
Do new panels come with built-in surge protection?
While surge protectors are separate components, current 2026 codes often require a Whole-Home Surge Protective Device (SPD) to be installed during a panel replacement. This device protects your sensitive electronics and smart appliances from external voltage spikes caused by utility switching or lightning.
Can I just replace the individual breakers instead of the whole panel?
If the panel enclosure and bus bars are in excellent condition, replacing a faulty breaker is a standard repair. However, if the bus bar shows signs of pitting, corrosion, or heat damage, the entire panel must be replaced. Installing new breakers on a damaged bus bar will not solve the underlying safety issue.
Do you provide 24/7 emergency service for panel failures?
Yes. A total panel failure or a main breaker that won't reset is a critical emergency. We provide 24/7 emergency response to diagnose the failure point and perform immediate repairs or temporary bypasses to ensure your home remains safe and powered until a full replacement can be scheduled.
