Frequently Asked Questions

Do I need a permit for an electrical panel upgrade or EV charger in Southlake, TX?

Yes. The City of Southlake Building Inspection Department requires electrical permits and final field inspections for main breaker panel upgrades, subpanels, and 240V dedicated circuits. Our licensed master electricians manage all permit filings and city inspection appointments directly.

Homes exceeding 5,000–6,000 square feet with multiple 5-ton AC units, electric pool heaters, double ovens, and dual Level 2 EV chargers exceed the safe 200A continuous power threshold. Upgrading to a 400A dual-bus panel ensures clean, un-interrupted power distribution without main breaker trips.

Most residential Level 2 EV charger installations take 2 to 4 hours. Our electrician mounts the wall charger, runs heavy-gauge 240V copper wiring to your panel, installs a dedicated double-pole breaker, and conducts full testing.

Panel-mounted Type 2 surge protectors suppress high-voltage lightning surges and power grid switching spikes up to 108,000 amps at the main service box before they reach refrigerators, HVAC control boards, smart TVs, and computers.
