Panel replacement is a safety project, not a capacity project. The service size stays the same; what changes is the load center itself. Diagnosis is visual and thermal: scorch marks on the busbar, breakers that wobble on their stabs, double taps, melted insulation at lugs, and heat signatures at connections under load. When a panel shows internal damage or belongs to a known problem line, replacement is the fix, because individual breaker swaps cannot repair a compromised busbar.
Montgomery's mid century neighborhoods are the core of this work. Homes built from the 1950s through the 1970s in Dalraida, Chisholm and Normandale commonly carry Federal Pacific Stab-Lok panels, whose breakers have a documented history of failing to trip under fault. Zinsco panels turn up too, with busbars that pit and arc where breakers clip on. Five months of heavy AC load every summer accelerates all of it, because thermal cycling loosens connections year over year.
Replacing a panel requires a permit and final inspection through the City of Montgomery Inspections Department even though the amperage does not change. Current code also reaches into the new panel: circuits that now require AFCI or GFCI breakers get them, the grounding and bonding are verified, and neutrals and grounds are separated properly on the bars. Alabama Power pulls the meter for the changeout and resets it after the city signs off.
The traps in this job are in the details. Old panels often hide multiwire branch circuits that must land on handle tied breakers in the new panel or the shared neutral overheats. Conductors cut short by the original installer need junction extensions done cleanly. And a panel that has been arcing sometimes conceals damaged insulation a foot up inside the wall, which is why we inspect the conductors before energizing rather than after the first burnt smell.
Technician insight
In Dalraida and Chisholm the panel brand is half the diagnosis. When the call describes a 1960s carport home with breakers that never seem to trip, we expect a Stab-Lok before the cover comes off, and the busbar usually confirms it.
A Stab-Lok Found During a Home Sale
A buyer's inspector flagged a Federal Pacific panel in a Chisholm ranch and the insurer would not bind coverage until it was gone. The changeout was permitted, the multiwire circuits were handle tied in the new panel, 2 heat shortened conductors were extended in junction boxes, and the passed city inspection record went to the insurer the same week.

How it works
- 1
Panel Inspection and Quote
Panel inspection with the cover off: busbar condition, breaker fit, thermal readings and conductor condition, followed by a written quote.
- 2
Permit and Meter Pull
Permit filed and the meter pull scheduled with Alabama Power.
- 3
Changeout Day
Old panel removed, new panel set, every circuit relanded with proper torque, multiwire circuits handle tied, panel labeled.
- 4
Inspection and Testing
City final inspection, meter reset, and load testing of every circuit before we leave.
Pricing
Price follows breaker count, required AFCI and GFCI types, conductor condition and panel location. A 20 circuit indoor changeout with healthy conductors is the base case; heat damaged wiring needing extensions, exterior 3R equipment, or relocating a panel out of a closet the code no longer allows all add cost. Everything is itemized in the written quote.
