How Long Does a Panel Upgrade Take

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.

Typical Timeline — What to Expect

  • Pre-work (scheduling & permits): We verify AHJ rules, pull the LADBS/LA County permit, and book utility disconnect/reconnect if needed.
  • Installation day: De-energize, swap meter-main/panel, update grounding & bonding, label circuits, restore power.
  • Final inspection: We schedule the final inspection and close out the permit; you receive as-built photos and the updated panel schedule.

Exterior relocations, long conduit routes, wall/finish preservation, service size changes, or coordination with PV/ESS can add time. We call these out in your written proposal.

What We Do on Installation Day

  • Replace meter socket / meter-main or panelboard listed for your service size
  • Install service conductors & raceway; verify working clearance (~30″ wide, 36″ deep; door opens 90°)
  • Set main OCPD, label the panel schedule
  • Verify grounding & bonding (water/gas bond, GES continuity; add/verify electrodes as required)
  • Provide service SPD and emergency disconnect labeling where adopted
  • Torque to spec, restore power, test circuits

Panel Upgrade with EV Charger: What to Expect

Planning for a future ev charger Installation in Los Angeles?

  • Add 1–2 hours for panel capacity checks and load calculations.
  • Potentially upgrade wiring to allow for a 200-amp service—adds 2–4 hours + permit/inspection time.

When It Takes Longer: Watch for These Factors

  • A. Complete Rewiring: Extensive rewiring adds 4–12+ hours.
  • B. Panel Relocation: Moving a panel (e.g., garage to utility area) may add full additional workday.
  • C. Inspection Scheduling: City timing can delay final approval (24 hours to a week).
  • D. Unexpected Issues: Aging wiring, damaged conduits, or tight panel spaces can stretch timelines.

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.
