Signs You Need a Panel Upgrade
Circuit breakers tripping repeatedly when running multiple appliances simultaneously.
Flickering or dimming lights when major equipment like air conditioning turns on.
Buzzing sounds, crackling noises, or burning odors originating from the breaker box.
Presence of fused boxes or outdated panel units that fail to meet modern safety codes.
Rust, moisture corrosion, or physical damage on the metal panel enclosure.
Insufficient open breaker slots to install new circuits for EV chargers or hot tubs.
Should You Repair or Replace Your Electrical Panel?
Minor issues like a single faulty breaker can often be repaired quickly. However, if your breaker panel is over 20 years old, shows signs of thermal damage, or lacks the capacity to support modern appliances, a complete panel replacement is the safest and most cost-effective long-term investment.
Frequently Asked Questions About Panel Upgrades
How do I know if my electrical panel needs to be replaced?
Signs include frequent breaker trips, flickering lights when appliances turn on, buzzing noises, or burning smells near the panel box. Outdated panel designs that do not meet modern standards also indicate an immediate need for replacement.
How long does a main panel upgrade take to complete?
Most residential panel replacements are completed within a single day. Power is temporarily shut off during installation, and our team works efficiently to restore full power before leaving your property.
What is the difference between a 100-amp and a 200-amp panel?
A 100-amp panel provides sufficient power for basic electricity needs in smaller homes, whereas a 200-amp panel delivers double the electrical capacity. A 200-amp panel is required for modern homes with central HVAC, electric vehicle chargers, and heavy kitchen appliances.
Do panel upgrades require municipal permits in Austin, TX?
Yes, main electrical service upgrades and panel replacements require permits and local utility coordination to ensure code compliance. Big Shoulders Electrical Services manages all permitting and inspection steps directly for you.
Can a new panel protect my home from electrical fires?
No. A hot outlet can signal a serious hazard. Stop using it and call us right away.
