Answer: 7-8 hrs
Explanation: For a straightforward residential panel replacement, the physical removal and installation typically takes about 4–8 hours. | | EDLab LLC | Answer: 6-7 hrs
Explanation: A full panel removal and replacement—same location, same service size, using existing wiring—typically lands in the 6–7 hour range. It’s a detailed, safety-critical process that involves far more than just swapping a metal box.
Why it takes 6–7 hours:
Utility disconnect and reconnect: SMUD or PG&E must shut off power at the service drop and return later to re-energize.
Removing the old panel: Circuits must be safely labeled, disconnected, and pulled out without damaging existing wiring.
Installing and mounting the new panel: The new enclosure must be leveled, secured, and aligned with existing conduit or service entry.
Transferring all branch circuits: Each circuit is trimmed, landed, torqued to spec, and organized to meet code.
Upgrading grounding and bonding: Most older homes need updated grounding electrodes, bonding jumpers, or water-pipe bonding.
Inspection and testing: The installation must pass city or county inspection before the utility reconnects power.
When it takes longer (7–8+ hours):
Damaged or short wiring that needs extension
Service mast or meter issues
Corroded grounding system
Tight or inaccessible panel locations
Multiple subpanels or add-ons
When it can be slightly faster (5–6 hours)
Clean, modern wiring
Straightforward like-for-like replacement
Easy exterior access
