What machinery wiring involves

A building owner wants the same answer every time. Is it safe, and when is it done. The work starts with finding out what is actually there. With machinery wiring, 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

Build-outs, tenant work, lighting and three-phase power for buildings that cannot go dark. 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

One crew handles residential, commercial and municipal work, so the person in your basement has seen harder jobs than yours. Everything goes in to code and passes inspection where one is required.

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

We test before we call it finished, every time. If something does not test right, we fix it while we are still there. Then the panel gets labeled, the scraps leave with us, and you get a clear account of the job.

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

Code, permits and inspection

Generators and transfer switches draw extra attention from inspectors, because a bad install can push power back into the utility lines. Expect a permit and an inspection on those even in places that are relaxed about smaller work, and expect us to handle both.

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.

What to do before we arrive

If there is a burning smell and you can safely reach the panel, shut off the affected circuit. If you cannot identify it, shut off the main. Do not run extension cords from another circuit as a workaround, especially for anything that heats.

Tell us what was plugged in when it happened and roughly what time it was. The more specific you are, the faster we find it.
