What occupancy sensors involves

When the power goes down in a business, the clock starts on lost revenue. The work starts with finding out what is actually there. With occupancy sensors, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

It starts with a look at the panel and the circuits involved. From there we tell you what has to be done, what can wait and what was never a problem at all.

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

Straight to the point: we find the problem, fix it to code and leave the space as clean as we found it. Anything that needs a permit gets one, and gets inspected.

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

Every quote starts with a visit. An electrician looks at the panel, the service size and the circuits involved, and asks what you plan to add over the next few years. The price you get reflects the building you actually have rather than a guess about a typical one.

The quote spells out what we will do, item by item, and what it costs. If we open up a box or a panel and find the job is different, we pause and walk you through it before any more work happens.

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.

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.

When to stop and call

If a breaker trips again right after you reset it, leave it off and call. Same if a faceplate feels warm to the touch or the panel is humming. Resetting a breaker over and over is how a small fault becomes a fire.

Do not keep resetting a breaker that will not hold. It is doing its job. Something downstream is drawing more than the circuit is rated for, or there is a fault, and repeated resets remove the one protection that is working.
