Q&A

My AFCI breaker in my Denver home keeps tripping. What could be causing this, and can you help?

Arc Fault Circuit Interrupter (AFCI) breakers are crucial for modern home safety but can be sensitive. In older Denver homes with aging wiring or newer builds with specific appliance loads, nuisance trips are common. We specialize in diagnosing the root cause—whether it's a wiring issue, a compatible device, or a need for a dedicated circuit—and provide a reliable repair or solution to restore safe, consistent power without compromising protection.

I'm considering an EV charger installation. What should Denver homeowners know about panel capacity?

Installing an EV charger is a significant electrical upgrade. A common issue we see in Denver is overloading an existing panel, which can be a safety hazard. Our process starts with a thorough inspection of your current electrical panel and home's power demands. We'll determine if a service upgrade or a dedicated sub-panel is needed to safely support the new 240-volt circuit, ensuring your charger operates reliably and your home's electrical system remains secure.

What's involved in an electrical panel upgrade or replacement with C4 Electrical?

A panel upgrade is a major project that enhances your home's safety and capacity. Our licensed master electrician with 46 years of experience handles the entire process: securing permits, safely disconnecting old service, installing a new panel with modern safety breakers (like AFCIs), and ensuring everything meets current Denver and National Electrical Code standards. We manage the project from start to finish, minimizing disruption and providing clear communication throughout.
