What substations involves

A service that was right in 1968 is undersized now. The work starts with finding out what is actually there. With substations, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

Plenty of calls end with a smaller bill than people braced for. A tripping breaker is often a single bad device, and a dead outlet is often a loose wire two boxes away.

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.

Ungrounded two-wire circuits are still common, along with three-prong outlets installed on top of them with no ground behind the plate. The outlet looks right. The tester says otherwise, and that changes how the job is planned.

How we do it

We show up when we said we would and explain the work before we start. Permits get pulled where they are required, and the job is not finished until it passes inspection.

Why this is worth doing properly

Electrical problems are slow. A loose termination can heat and cool thousands of times before it finally fails, and by then the damage is inside the box, the insulation and sometimes the framing around it. Proper work is about the long run: wire sized correctly for the load and every connection made the way the manufacturer and the code intend.

The cost of doing it right the first time is almost always lower than the cost of doing it twice. We would rather tell you the job is bigger than you hoped than come back in two years.

Scheduling and how long it takes

Most scheduled jobs start within a few days. Anything needing a village permit or a utility disconnect waits on those offices, and we will tell you up front how long that usually takes. Emergencies skip the line and get same-day attention.

If you are coordinating with other trades, tell us early. Rough-in has to happen before insulation and drywall, and the inspection has to happen before the walls close. We fit into that sequence rather than holding it up.

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

Leave the panel cover on. Flipping a breaker is fine. Taking the dead front off to look inside is not, because the service conductors at the top stay live even with the main off. We will open it when we get there.

Do not try to open the panel or take a device apart. Just tell us what you noticed and when, and we will take it from there.

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.
