What generator installation involves

The transfer switch is the part that decides whether backup power actually works. The work starts with finding out what is actually there. With generator installation, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

The first step is finding out what is actually wrong. Sometimes it is one loose connection at a device, and the fix is an hour. We will tell you that plainly instead of selling a bigger job.

Where this comes up

Standby generators, automatic transfer switches and emergency power systems. Most of these calls come from Des Plaines and the surrounding suburbs, but we take them anywhere in our service area.

It comes up most during a remodel. The walls are open, the old wiring is right there, and it is the cheapest moment the building will ever give you to fix what is behind them. Once the drywall is back, the same repair costs more.

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 changes with an older building

Buildings in this part of Illinois cover about a century of wiring practice. Knob-and-tube in the oldest, cloth-insulated branch circuits after that, aluminum wiring in a stretch of the sixties and seventies, and modern copper since. Each one fails differently and each one has its own repair path.

We look at what is actually in the walls before quoting, because guessing from the year the house was built is how people end up with a surprise halfway through.

Who actually shows up

A licensed electrician from our own crew. Residential, commercial or municipal, the same people do the work and hold it to the same standard. Nobody gets handed off to a subcontractor because the job is small.

You get told who is coming and roughly when. If we are running late you get a call, which should be the baseline in this trade and somehow is not.

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.

What to do before we arrive

If the panel itself is hot, buzzing or smells, do not touch it at all. Shut off the main only if you can reach it without leaning on the box. Otherwise keep clear and tell us that when you call.

Write down when the problem started and what else was running at the time. Those two details save a lot of searching.

The transfer switch is the system

People buy a generator and think of the engine as the product. The part that decides whether backup power actually works is the transfer switch, because it is what keeps generator power from backfeeding onto the utility line where it can kill a lineman.

Automatic switches sense the outage and start the unit without anybody being home. Manual switches cost less and need somebody present. Which one is right depends on what you are protecting.
