How It Works
We keep the process straightforward so you know what to expect at each stage.
We visit your property, evaluate your electrical panel, and determine the right generator size based on your actual power needs.
We handle the permit paperwork and coordinate placement, fuel connections, and transfer switch specs before any work begins.
Our crew installs the generator, wires the transfer switch, connects to your panel, and tests the full system before we leave.
We walk you through how to operate your generator, what to check periodically, and how the automatic transfer switch functions during an outage.
Frequently asked
Common questions get answered quickly so the page feels more trustworthy before someone reaches out.
Q1
Yes, most generator installations in Maine require an electrical permit. Klein Electric LLC handles the permitting process as part of the job so you do not have to coordinate with the municipality on your own.
Q2
A standby generator is permanently installed outside your home and starts automatically during an outage. A portable generator is movable but requires manual setup and cannot power your whole home the same way a standby unit can.
Q3
Generator sizing depends on which circuits or appliances you need to power. During our site visit, we calculate your load requirements and recommend a unit that fits your actual usage, not a one-size number.
Q4
A transfer switch disconnects your home from the utility grid before the generator powers your circuits. This protects utility workers from backfeed and keeps your generator from being damaged when grid power returns.
Q5
Yes. We install generators for businesses throughout Maine, including properties in Bangor, Augusta, and Waterville. Commercial jobs involve additional load planning and sometimes a larger transfer switch or sub-panel work.
Q6
We serve customers across the state, including Belfast, Rangeley, Freeport, Winthrop, Augusta, Waterville, and Bangor. If you are outside those areas, contact us and we can confirm coverage.
Q7
Most residential installations are completed in one day once permits are approved and materials are on site. Larger commercial projects or jobs requiring panel upgrades may take longer depending on scope.
Q8
Often yes. If your current panel does not have capacity for a transfer switch or additional circuits, we can coordinate a panel upgrade at the same time to avoid scheduling a second visit.
