What electrical service 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 electrical service upgrades, 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

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 and insured on every call. No job is too small to do properly, and no shortcut is worth an inspector’s red tag. We would rather do it once.

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

A photo of a panel tells us the brand and not much else. It does not show a loose lug, a scorched bus bar or aluminum on the branch circuits. That is why we come out and look before we put a number on anything, large job or small.

We look before we put a number on anything. The quote is in writing, broken out by item, and it says exactly what we are doing. What you approve is what we do.

Code, permits and inspection

Commercial and multi-unit work often needs drawings or a load calculation filed with the permit application. We prepare what the municipality asks for, so the permit is approved without a round of corrections and the inspection follows the plan that was filed.

We deal with whichever jurisdiction the job sits in. We pull the permit, we schedule the inspection, and we are there when the inspector walks it. You get the paperwork at the end, which matters when you sell the building or when an insurer asks.

Copper, aluminum and what is in your walls

Aluminum branch wiring went into a lot of houses in the late sixties and early seventies. It is not automatically dangerous, but it expands and contracts more than copper, which loosens terminations over time, and it needs devices and connectors rated for it.

The repair is usually not a full rewire. Proper connectors at every termination, done thoroughly, solves most of it. Anybody quoting you a whole-house rewire on sight has not looked.

The warning signs people ignore

The breaker that trips once a month gets ignored because it holds afterward. The outlet that only works when the plug is wiggled gets a strip of tape over it. Both are connections failing slowly. Slow failures give you time, but they do not fix themselves.

A buzz from a switch or dimmer is not normal noise. It usually means a loose connection arcing, and arcing generates heat.

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.
