Here are common questions we hear from Livermore area homeowners and business owners — answered clearly, professionally and honestly by TopTech Electrical.
Q: Do I need a licensed electrician for a panel upgrade in Livermore?
A: Yes — California code requires a licensed C-10 electrical contractor (license #1138519 for us) to perform panel upgrades. It ensures safety, code compliance and proper permitting.
Q: How long does an EV charger installation take?
A: For most homes in the Tri-Valley, a Level 2 EV charger installation takes 1-2 days: site assessment, circuit run, installation and testing all included.
Q: What signs indicate I may need rewiring or a sub-panel?
A: Flickering lights, tripping breakers, hot outlets or frequently used extension cords are red flags — we evaluate your system and recommend upgrades.
Q: Can you work with my business’s tenant improvement schedule?
A: Absolutely — we coordinate with general contractors and building managers in Livermore and the East Bay to deliver wiring and lighting on time with minimal business disruption.
Q: How often should I have an electrical safety inspection?
A: We recommend a full safety inspection every 3–5 years for older homes or every major remodel. Businesses may require annual inspections depending on code and insurance.
