Question Answers
I live in an older Lafayette home and am concerned about my aluminum wiring. Can OSJ Electric help?
Absolutely. Addressing aluminum wiring, a common issue in many older Contra Costa County homes, is a specialty of ours. We perform thorough inspections to assess the risk and can implement safe, code-compliant solutions, which often involve installing special connectors or recommending a partial or full wiring upgrade to modern copper. Our priority is eliminating fire hazards and ensuring your home's electrical system is safe for your family.
I'm considering an electric vehicle. What does an EV charging station installation involve?
Installing an EV charger at your Lafayette home starts with a detailed assessment of your electrical panel's capacity. Our certified electricians will evaluate if your current system can support the added load or if a panel upgrade is recommended. We handle the entire process—from obtaining any necessary permits to the professional installation of a dedicated circuit and the charging unit itself—ensuring a safe, efficient, and code-compliant setup tailored to your vehicle's needs.
My circuit breaker trips frequently. Is this a repair or a full panel replacement?
Frequent tripping can indicate several issues, from a simple overloaded circuit to a more serious problem with the breaker itself or an outdated panel. Our electricians will first diagnose the root cause through a careful inspection. We might repair or replace a faulty breaker, but if the panel is old, undersized, or shows signs of wear—common in homes with expanding electrical needs—we'll discuss the benefits of a modern panel upgrade for improved safety and capacity.
