What EV charging infrastructure involves

Underground work is judged years later, when somebody has to find it. The work starts with finding out what is actually there. With EV charging infrastructure, 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

Street lighting, traffic signals, pump stations and underground distribution. 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

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 this is worth doing properly

A bad electrical connection does not fail politely. It heats, it chars the box around it, and eventually starts a fire inside a wall where nobody can see it. That is why the licensing exists and why an inspector looks at the work. Every connection has to be tight, every conductor sized for the load it will actually carry, every box accessible afterwards.

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

We answer 24/7 and an emergency gets a crew the same day. Planned work typically starts within a few days of the go-ahead, unless a permit or a ComEd appointment has to land first.

A small repair is usually one visit. A service upgrade has several moving parts: our install, the village inspection and ComEd restoring power. We tell you which step you are waiting on at every point, so the date never goes quiet.

Code, permits and inspection

An inspector is checking the things you cannot easily see later: box fill, conductor size, grounding and bonding, clearances at the panel, and whether each circuit has the protection it needs. Passing means a second trained set of eyes agrees the work is safe.

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.

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

If an outlet or switch is sparking or scorched, leave it alone and turn off its breaker. Do not pull the plug from a device that is visibly burning at the receptacle. Keep people and pets out of that room until we get there.

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