Common Questions

Can an electrical inspection help if my backup generator in Sonora won't connect properly?

Absolutely. A thorough electrical inspection from Case J L & Sons is the best first step. We'll examine your transfer switch, wiring connections, and the overall integration with your home's main panel—common points of failure for generators in our area. Our inspection will pinpoint whether the issue is a faulty connection, an overloaded circuit, or an installation error, allowing us to provide a safe, permanent fix to ensure your generator is ready when you need it.

Why does my arc fault breaker keep tripping, and how can an inspection help?

Arc fault circuit interrupters (AFCIs) are sensitive safety devices required in modern homes to prevent electrical fires. Frequent tripping in Sonora homes can be caused by damaged wiring behind walls, faulty appliances, or even loose connections. Our detailed electrical inspection involves specialized testing to locate the source of the nuisance arc—whether it's in a specific circuit, an outlet, or the wiring itself. We'll identify the root cause and recommend the precise repair needed to restore reliable power and safety to your home.

What does a local electrician look for during a whole-home electrical inspection?

Our whole-home inspection for Sonora residents is comprehensive. We check your main service panel for proper capacity and safe connections, test all AFCIs and GFCIs for functionality, inspect wiring for damage or deterioration common in our climate, verify grounding systems, and assess all outlets and switches. We pay special attention to systems like backup generators and areas prone to the issues you've described. The goal is to provide you with a complete picture of your electrical system's health and safety, along with a clear, prioritized list of any recommendations.
