What switchgear upgrades involves

Charging at home only works if the panel behind it can carry the circuit. The work starts with finding out what is actually there. With switchgear upgrades, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

A diagnosis comes before a scope. Once we know what is happening and why, we lay out the work, and you decide how much of it you want done now.

Where this comes up

Level 2 at home, DC fast and fleet charging for business and municipal sites. Most of these calls come from Des Plaines and the surrounding suburbs, but we take them anywhere in our service area.

A home sale is often when this surfaces. An inspector flags aluminum branch wiring, a fuse box or a panel with doubled-up breakers, and suddenly there is a deadline. We can tell you which items are urgent and which are only noted.

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.

Why it usually cannot wait

Electrical problems do not stay the same size. A loose connection heats up, the heat oxidizes the metal, the oxidized metal raises the resistance, and the resistance makes more heat. That loop runs in one direction only and it ends at a scorched box.

If something is tripping, buzzing, warm to the touch or smells like hot plastic, that is the system telling you where the problem is while it is still cheap to fix.

How we quote it

We price after an electrician has had the panel cover off and traced the circuits involved. It takes a little longer than a number over the phone, and it means the price you approve is the price on the invoice unless the scope changes.

You get a written quote with the work broken into items, so you can compare it, question it or ask us to adjust the scope. Once you approve it, that is the job. Changes only happen with your say-so.

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.

Materials and why they matter

Devices are not all the same. A fifty-cent backstabbed outlet holds the conductor with a spring clip; a commercial-grade one clamps it under a screw plate. The second kind is a couple of dollars more and it is the reason the connection is still tight in fifteen years.

We use commercial-grade devices as standard. It is a small share of the job cost and it is the part most likely to fail if you go cheap on it.

What to do before we arrive

Whole house dark? Check whether the neighbors still have lights. If the street is out, that is a ComEd call, not ours. If it is only your building, leave the main off if you already shut it and wait for us.

Snap a photo of the panel, the outlet or whatever looks wrong. A picture plus a short history of the problem often tells us what to bring.

Load calculation comes first

An EV charger is a continuous load, which means the code requires the circuit to be sized at 125 percent of its rating. A 48-amp charger therefore needs a 60-amp circuit, and that has to fit inside what the service can already carry alongside the furnace, range, dryer and air conditioning.

We run the calculation before anything gets ordered. Sometimes the answer is that the panel takes it as-is, sometimes it needs a load management device, and sometimes the service genuinely needs upgrading first. You get the real answer rather than the convenient one.
