Replacement is about the condition of the panel, not the size of the service. The candidates are specific: Federal Pacific Stab-Lok panels, whose breakers have a documented history of failing to trip under fault, Zinsco panels, whose busbars burn where breakers clip on, fuse boxes still serving older in town homes, and any panel with heat damage, water intrusion, rust on the busbar or a smell of burnt insulation. If your 100 amp service meets your loads, the replacement stays 100 amps and the job stays smaller than an upgrade.
Tuttle's older housing keeps this work steady. In town homes built midcentury still run fuse panels with a 60 or 100 amp service, and 1960s through 1970s houses are exactly the era where Federal Pacific and Zinsco shipped in volume across Oklahoma. Water is a local aggravator: panels on north walls and in garages take blown rain during spring storms, and a meter base that has lost its seal lets water track down the service entrance conductors into the panel, rusting the busbar from the top down. That corrosion is a replacement trigger even on a young panel.
A like for like panel replacement is still permitted work. Inside city limits the permit and inspection run through the City of Tuttle Building and Code department, outside they fall to county and state jurisdiction, and the replacement is the moment the grounding electrode system, bonding and AFCI or GFCI protection get brought up to the National Electrical Code as adopted in Oklahoma where required. A brief utility or co-op disconnect is usually scheduled for the swap.
Field notes that matter: a Stab-Lok panel can look pristine and still be dangerous, because the failure is inside the breaker mechanism, so cosmetic condition is not a pass. Zinsco damage hides behind the breakers, and the panel has to be opened and the breakers pulled to see the bus. And a house that blows fuses constantly does not need bigger fuses, it needs the overloaded circuits found, because oversizing a fuse on old cloth wiring is how attic fires start.
Electrical Panel Replacement Services We Offer
✓Federal Pacific Stab-Lok Replacement
Removal of FPE Stab-Lok panels and replacement with a modern load center, with every circuit relanded and tested.
✓Zinsco Panel Replacement
Replacement of Zinsco and Sylvania-Zinsco panels, including busbar damage assessment and clean termination of existing circuits.
✓Fuse Box Replacement
Fuse panels converted to breaker panels at the same service size, with circuit mapping so every fuse's job is preserved and labeled.
✓Damaged Panel Replacement
Panels compromised by water, rust, heat or storm damage replaced, including meter base sealing where the water came from above.
✓Breaker and Busbar Repairs
Where a quality panel has one problem, failed breakers or a damaged section can sometimes be repaired instead of replacing the panel.
✓Panel Relocation
Panels moved out of closets, bathrooms and blocked corners where code no longer allows them, restoring legal working clearance.
How it works
- 1
Panel Evaluation
The panel is opened, the bus and terminations inspected, and you get an honest read: replace, repair, or leave alone. Not every old panel needs to come out.
- 2
Written Price and Scheduling
The quote covers the panel, code required protection updates and the permit. The utility or co-op disconnect is booked so the swap happens on one scheduled day.
- 3
The Swap
Old panel out, new load center in, every branch circuit relanded, torqued to spec and labeled. Power is typically back the same day.
- 4
Inspection
The inspector verifies the work, and you keep the documentation, which insurers increasingly ask for on FPE and Zinsco homes.
Pricing
Pricing turns on circuit count, access and what the old panel hides. Crowded panels with double taps take longer to reland, and required AFCI or GFCI protection moves the number more than the panel itself. Written price after the evaluation.
