What main disconnects involves

The service is where the building meets the grid. Everything else is downstream. The work starts with finding out what is actually there. With main disconnects, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

We tell you what we find before we tell you what it costs. If the scope is smaller than you expected, it gets smaller. That happens more often than people assume.

Where this comes up

Services, switchgear, transformers and the distribution behind the meter. Most of these calls come from Des Plaines and the surrounding suburbs, but we take them anywhere in our service area.

New load on old wiring is the most common version. A heat pump or a charger for the car goes in, the circuits that were fine until then start complaining, and the real question becomes whether the existing service can carry it at all.

How we do it

Every connection gets tightened properly and every wire is sized for the load it carries. Where the village requires a permit, the inspector signs off on it, so the standard is on paper as well as in the wall.

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

Our electricians are licensed and insured, and they are the same ones who handle our commercial and government work. A homeowner with one flickering light gets that same experience. That is how the owner set it up from day one.

You will know who is coming and roughly when. If traffic or an earlier job pushes that back, we call to say so. It is a small thing that a lot of this trade still gets wrong.

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.

When to stop and call

Shut the breaker off and call us if an outlet or switch shows brown or black marks, if you smell something hot that you cannot trace, or if a panel is making noise. Those are not wait-and-see problems.

If you get even a mild shock from a faucet, an appliance or a light switch, stop using it and call. A tingle means current is going somewhere it should not, and the ground path that was supposed to carry it is not doing its job.

Service size is a ceiling on everything

The service is the limit every other circuit lives under. A 100-amp service was generous when houses had one air conditioner and a gas range. Add electric cooking, a heat pump, a car charger and a finished basement and it stops being enough.

Upgrading means coordinating with ComEd, replacing the meter socket and mast, and sizing the new panel for what the building will need in ten years rather than exactly what it needs today.
