What transfer switches involves

The wiring in an older Illinois house was never sized for how people live now. The work starts with finding out what is actually there. With transfer switches, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

You see the problem before you see a price. We point to what we found, explain why it matters and then tell you what fixing it takes. No pressure to approve on the spot.

Where this comes up

Panels, rewires, outlets, lighting and the circuits behind everything in a house. Most of these calls come from Des Plaines and the surrounding suburbs, but we take them anywhere in our service area.

A lot of the work in Illinois starts in a house or building that has been added onto more than once. Each addition borrowed power from whatever circuit was closest, and by now nobody knows which breaker feeds what. Sorting that out is part of the job.

How we do it

Licensed electricians, to code, cleaned up behind us. Where the village requires a permit we pull it and we meet the inspector, so the work is on record and it passes.

What changes with an older building

Buildings in this part of Illinois cover about a century of wiring practice. Knob-and-tube in the oldest, cloth-insulated branch circuits after that, aluminum wiring in a stretch of the sixties and seventies, and modern copper since. Each one fails differently and each one has its own repair path.

We look at what is actually in the walls before quoting, because guessing from the year the house was built is how people end up with a surprise halfway through.

Who actually shows up

One crew covers all of it, from a single outlet in a house to service work on a municipal building. You get the same licensed electricians no matter how big the job is, and we do not farm out pieces of it.

Being on time is part of the job. You are told who is coming and when, and a late arrival gets a call ahead of time. Too many contractors skip that step.

What the permit actually buys you

A permit puts the work on the public record for the address. When the building changes hands, that record is evidence the electrical was done and checked. Without it, a buyer's inspector treats everything they find as suspect.

It also means the work was sized and installed to the code edition in force, not to whatever was normal when the building went up.

Grounding and bonding

Grounding is the part nobody sees and the part that decides whether a fault clears safely. The ground path has to be continuous and low-impedance from every device back to the service, and the neutral and ground can only be bonded together in one place.

A neutral bonded to ground in a subpanel is one of the most common defects we find. It works right up until it does not, and then it puts current on metal that people touch.

What to do before we arrive

If an outlet or switch is sparking or scorched, leave it alone and turn off its breaker. Do not pull the plug from a device that is visibly burning at the receptacle. Keep people and pets out of that room until we get there.

Leave the affected circuit off if it smells hot or keeps tripping. Otherwise, just remember what you were using when it acted up.
