What battery backup systems 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 battery backup systems, 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

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.

Insulation is the quiet problem. Cloth-wrapped conductors from decades ago go brittle inside the box, and they crack the moment somebody moves them to swap a switch. A small job becomes a careful one, so we check before we promise a time.

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 clean up the work area and leave the place the way we found it, minus the problem. Where a permit was pulled, the inspection closes the job and you get the paperwork for your records.

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

Write down which breakers you already flipped and in what order. If several are off now, leave them that way rather than trying to put things back. It is faster for us to work from a known state than to undo guesses.

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.
