What municipal EV charging involves

An EV charger is a big continuous load on a panel that was never asked for one. The work starts with finding out what is actually there. With municipal EV charging, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

We explain the job in plain terms before anything starts: what we are changing, why, and how long the power will be off. If a smaller fix does the job, that is the fix you get.

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.

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

We protect the floors, keep the mess contained and haul out what we remove. The work itself goes in to code, and where a permit applies, it gets pulled and inspected.

What we see go wrong

Most of the bad work we find was not done by an electrician. It was a handyman, a previous owner or somebody who watched a video. Backstabbed outlets, undersized conductors, missing grounds, neutrals and grounds bonded in a subpanel, junctions buried inside a wall with no box.

None of that is visible from the living room. It surfaces during a remodel, a home inspection, or the day a breaker stops holding.

What happens when we are done

Most panels we open have labels that stopped being true years ago. Ours come out accurate. Every circuit we work on is tested and named in the panel directory, so the next electrician, or you at midnight with a tripped breaker, knows exactly what is what.

Where a permit was pulled you get the closed inspection. Where documentation exists, you get it.

The inspection is the point

An inspection is an independent check that what went behind the drywall matches what was supposed to. Work that passes has been verified by somebody with no stake in the invoice.

That is also why we would rather you hire a licensed contractor than the cheapest number you can find. Unpermitted electrical work is a problem you inherit, and it usually surfaces at the worst moment.

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

Outdoor problem, like a damaged service mast or a line down near the house? Stay well back from it and keep others back too. Do not try to move anything. That one involves ComEd as well as us, and we will coordinate it.

Keep track of patterns. Does it happen in the morning, in the rain, when the microwave runs? Patterns point us straight at the fault.

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.
