What generator systems involves

A server room is mostly a power and cooling problem. The computing is the easy part. The work starts with finding out what is actually there. With generator systems, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

We explain the job in plain terms before anything starts: what we are changing, why, and how long the power will be off. If a smaller fix does the job, that is the fix you get.

Where this comes up

Critical power, UPS, redundancy and the electrical behind server rooms. Most of these calls come from Des Plaines and the surrounding suburbs, but we take them anywhere in our service area.

Previous work is the wild card. Plenty of Illinois homes and shops have circuits somebody extended on a weekend, splices buried in a wall with no box, and breakers upsized to stop a nuisance trip. We find those first, because they decide what is safe to build on.

How we do it

Every connection gets tightened properly and every wire is sized for the load it carries. Where the village requires a permit, the inspector signs off on it, so the standard is on paper as well as in the wall.

Why this is worth doing properly

Cheap electrical work usually gets paid for twice. The first time is the low price. The second is when an inspector, a buyer’s home inspection or a failed device finds what was skipped, and somebody has to open the walls back up to fix it. Doing it right the first time is the less expensive path, even when the first number is higher.

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.

Some dates are ours to set and some belong to somebody else. The install day is ours. The village inspection and any ComEd disconnect are not, so we book those first and build our part of the schedule around them.

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.

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.

When to stop and call

When something electrical smells hot or looks burnt, the safest thing you can do is stop using it and call. Do not open the panel to investigate. Tell us what you saw and we will tell you how urgent it is.

If you get even a mild shock from a faucet, an appliance or a light switch, stop using it and call. A tingle means current is going somewhere it should not, and the ground path that was supposed to carry it is not doing its job.
