Panel repair · Wichita & Sedgwick County · 67217
South Wichita is largely post-war ranch housing, which puts a lot of it in the years when aluminium service entrance conductors were standard and when 100 amp was considered generous. Both facts shape what we find at the board.

Aluminium at the service is not the same subject as aluminium branch wiring, and the two get confused constantly. At the panel, aluminium service entrance conductors are entirely normal and still installed today. What matters is how they are terminated.
Mostly 1950s to 1970s originals or first replacements, commonly 100 amp, with aluminium service entrance conductors landing on the main lugs. Aluminium expands and contracts more than copper under load, so those lugs need to have been torqued correctly and treated with the right compound. Frequently they were not.
Obsolete makes are well represented too. Federal Pacific and Zinsco boards both went into this housing in numbers, and split-bus designs are common enough that many owners have never had a single main breaker to switch off.
Not by itself. Aluminium service entrance conductors are standard, current and perfectly safe when terminated correctly. The failure is at the connection: a lug that was undertightened at installation, or overtightened, or landed without the antioxidant compound the terminal calls for.
All three show up the same way on a thermal reading, which is heat where there should be none. That is the check we run first on any board in this part of the city, before anything else gets looked at.
About thirty-two minutes from the yard, with the same-day slot held for hot, humming or smoking boards. South Wichita is inside the city, so MABCD permits panel replacement, service changes and subpanels from 271 W 3rd St N, Suite 101 on (316) 660-1840, inspected against the 2023 National Electrical Code, in force since January 1, 2025.
The outer door is safe to open, and the label is on the inside of it. Federal Pacific boards carry FPE, Federal Pacific or Federal Noark, and their breakers say Stab-Lok. A Zinsco will be badged Zinsco, Sylvania or GTE-Sylvania, and the breaker handles are usually coloured rather than black. Both makes went into this housing in numbers.
Never remove the inner cover to look. The bus behind it stays live with the main breaker off, because it sits on the utility side of that breaker. A photograph of the open door and the breaker layout is enough for us to identify the make without driving out.
South Wichita covers the residential streets south of Kellogg down toward the Haysville line.

Breakers had been tripping for months and two other electricians replaced them without fixing anything. Turned out the bus stabs had lost their grip so nothing was seating properly. That is the board, not the breakers. Replacement was the right call and he showed me why rather than telling me.

Solid job on a service upgrade. Detailed quote, no surprises on the invoice, permit and inspection all handled. Four stars only because the first appointment slipped a day for an emergency ahead of me, though they did call rather than leave me sitting there.

Aluminium service entrance conductors are standard and still installed today. They are safe when terminated correctly, which means torqued to specification and, where the terminal calls for it, treated with antioxidant compound. The risk is at the connection rather than in the conductor, and it shows as heat on a thermal reading.
No, and they get confused constantly. Branch circuit aluminium, used in some houses from the late 1960s, is a separate subject about receptacle and switch terminations throughout the house. Aluminium at the service entrance is normal and current. Different conductors, different concerns, different work.
That is a split-bus board, common in this housing. Several breakers at the top of the panel each feed a section rather than one main feeding everything. In an emergency you would need to switch those top breakers off individually. It is one of the practical reasons people replace them.
Look for what did not come back after power was restored. A dead circuit, a breaker that will not hold, an appliance that will not start, or a board that hums or feels warm. We test the board, the breakers and the service equipment together and document the findings with readings for your insurer.
Give us the street and the name on the panel door. You will get the next slot running in this area, and a same-day one if the board is hot, humming or giving off any smell.
