How Long Does a Panel Upgrade Take? Your Complete Timeline Guide
Most straightforward 200A panel swaps finish in one working day after permit approval and utility scheduling. Projects take longer when we add new conduit runs, relocate the service/panel, preserve stucco/drywall, trench for feeders, or coordinate PV/ESS interconnections. We confirm your AHJ requirements and give you a written schedule at the assessment.
Wondering how long does a panel upgrade take? At farashi electric, we handle everything—from planning and permitting to electrical panel upgrade in Los Angeles—in just a single day for standard jobs, and up to two days for more complex scenarios. This detailed guide breaks down every step, helping you set clear expectations, avoid surprises, and get your system upgraded efficiently and safely.
What Affects How Long Does an Electrical Panel Upgrade Take?
Size and complexity: A basic swap usually completes in 4–8 hours with two technicians . Add rewiring or relocation, and it can span multiple days
Panel amperage: Installing a 200-amp service typically needs one workday (6–10 hours)
Pre-existing wiring condition: Old or damaged wiring adds extra time for electrical rewiring in Los Angeles.
Location & permits: Moving the panel or dealing with city inspections extends the timeline. Surface-mounted work often wraps in a day; flush-mounted may require two workdays plus inspections.

Permits & Utility Coordination (Los Angeles)
Electrical permits are required for panel upgrades in the City of Los Angeles (LADBS) and LA County. Many residential swaps qualify for Express/e-Permits. We handle the permit, then coordinate utility disconnect/reconnect (e.g., LADWP/SCE), and schedule the final inspection with your AHJ.

It depends on AHJ workload and scope. Many residential projects use Express/e-Permits; we schedule the final inspection and coordinate utility as needed.
