Ferraina Electrical Contracting, Inc. - Glendora's Licensed Electrical Company

An electrical inspection by our certified electricians is the best proactive step for older homes. We meticulously examine your wiring, outlets, and electrical panel for signs of wear, corrosion, or outdated components that are common culprits of short circuits. We identify overloaded circuits and potential fire hazards, providing you with a clear report and recommendations to upgrade your system for safety and reliability, giving you peace of mind.

A professionally installed transfer switch is critical for safety and functionality. It creates a secure, code-compliant connection between your generator and your home's electrical panel, preventing dangerous backfeed into utility lines that could harm utility workers or neighbors. Our expert installation ensures your essential circuits—like sump pumps, refrigerators, and medical equipment—receive power automatically and safely during an outage, protecting your home and family.

During an inspection, we focus on aging components prevalent in Glendora's older homes. This includes checking for knob-and-tube or aluminum wiring, evaluating the capacity and condition of your main service panel, testing for faulty grounding, and inspecting for overloaded circuits with multiple high-wattage appliances. We also assess the integrity of outlets and switches, looking for signs of overheating or damage that often lead to short circuits, ensuring your system is safe for daily use.
