Q&A

How can an electrical inspection from David Dunham help with my generator transfer switch on Nantucket?

Generator transfer switches are critical during Nantucket storms, but salt air and humidity can cause corrosion and connection failures. Our inspection thoroughly tests your transfer switch, checks for corrosion, and verifies it will operate safely and automatically when needed, ensuring your home stays powered during an outage.

Why are my outdoor outlets failing, and how does your inspection address this common Nantucket issue?

Salt spray and moisture are harsh on outdoor electrical components, leading to rapid corrosion and dangerous shorts or GFCI failures. Our inspection includes a detailed check of all exterior outlets, covers, and wiring for corrosion and water damage. We identify compromised outlets before they become a safety hazard and recommend weatherproof upgrades suitable for our island climate.

What specific things do you look for in a Nantucket home electrical inspection?

Beyond standard safety checks, we focus on island-specific concerns. We examine the main panel and outdoor disconnects for corrosion, test all GFCI outlets (especially in damp areas), verify grounding systems are intact, and assess the condition of wiring in attics and crawl spaces for signs of moisture or pest damage. Our goal is to catch small, local issues before they become major repairs.
