Main Electrical Service Panel
Your electrical service panel is more than just a switch—the backbone keeps your home running smoothly. From lighting up rooms to safeguarding against surges, it’s the unsung hero ensuring your home stays powered and safe.
Understanding Main Electrical Service Panels
The main service panel acts as the nerve center of your home’s electrical system. Serving as a switchboard, it receives incoming power from the utility company and efficiently distributes it to circuits supplying lights, outlets, appliances, and various devices throughout your house.

FAQ's
How do I know if my electrical panel needs to be upgraded?
Common signs include frequently tripping breakers, flickering lights, a panel that feels warm to the touch, burning smells near the box, or a 100-amp panel in a home with modern appliances and devices. If your home is more than 25 years old and hasn’t had a panel upgrade, it’s worth having a licensed electrician assess it. McCarthy Electric offers free estimates — contact us to schedule yours.
How long does a panel upgrade or replacement take?
Most panel upgrades are completed in a single day. The exact timeline depends on the scope of work, whether a permit inspection is required, and the size of your home’s electrical system. Our team will walk you through the timeline during your estimate so there are no surprises.
Does a panel upgrade require a permit in Lynnwood, WA?
Yes. Panel upgrades in Lynnwood and throughout Snohomish County require a permit and inspection through the City of Lynnwood Building & Code Compliance Division. McCarthy Electric pulls all required permits on your behalf — work is inspected and completed to Washington State code under License No. MCCARET796DQ
What size panel does my home need?
Most modern homes require a 200-amp panel, especially if you have or plan to add an EV charger, heat pump, or other high-draw appliances. Older homes may still have 100-amp or even 60-amp service, which often can’t safely support today’s electrical loads. We perform a formal load calculation on every job to recommend the right panel size for your specific needs.
Can McCarthy Electric upgrade my panel and install a smart panel at the same time?
Yes — and it’s often the most cost-effective approach. If you’re already replacing your panel, upgrading to a smart panel like SPAN gives you real-time energy monitoring, circuit-level control from your phone, and seamless integration with solar, battery backup, and EV charging. Ask about our smart panel services when you request your estimate.
