Power outages in Greendale, WI can last hours or days, disrupting work, risking food safety, disabling medical equipment, and leaving families in the dark. Our licensed electricians install standby generators that activate within seconds of a power loss, automatically, without you lifting a finger, protecting everything you depend on.
Generator Installation
The frequency and duration of power outages in Greendale, WI and throughout the region has increased significantly in recent years, driven by aging utility infrastructure, more frequent extreme weather events, and grid demand patterns that strain transmission capacity. For most Greendale, WI households, a brief outage is an inconvenience. For households with medical equipment, refrigerated medications, home-based businesses, or young children, even a few hours without power creates real hardship. For businesses, every hour of downtime is measured in lost revenue, potential food safety liability, and customer dissatisfaction.
There are two primary categories of backup power for Greendale, WI properties: portable generators and standby generators. Portable generators are less expensive but require manual setup, fuel storage, outdoor placement, and a transfer switch or interlock kit to safely power your home. Standby generators are permanently installed units that run on natural gas or propane, connect through an automatic transfer switch (ATS), and activate automatically within 10 to 30 seconds of a utility outage, with no human intervention required. Our Greendale, WI team installs both types but specializes in standby systems for their superior reliability and convenience.
Sizing a generator correctly for your Greendale, WI home or business requires a load analysis, calculating which circuits you want the generator to support, the starting and running wattage of the appliances on those circuits, and whether you want essential-circuit coverage or whole-home power. A common mistake in generator installation is over-sizing, purchasing a 22kW generator for a home that would be completely served by a 14kW unit, paying significantly more for capacity that's never used. Our Greendale, WI electricians perform proper load calculations before any generator recommendation so you get exactly the capacity you need.
The automatic transfer switch (ATS) is the component that makes standby generator power automatic. Installed between the utility meter and your main panel, the ATS constantly monitors incoming utility voltage. When it detects a voltage drop or loss of power, it disconnects your Greendale, WI home from the utility grid, starts the generator, confirms the generator has reached stable output voltage, and switches your home's load to generator power, all within 10 to 30 seconds. When utility power returns, the ATS reverses the sequence, switches back to utility power, and shuts down the generator after a cool-down period. The whole process is invisible to you.
Generator installation in Greendale, WI requires coordination across multiple systems and authorities: a gas line connection (handled by a licensed gas contractor in coordination with our electrical scope), a concrete pad or composite base installation, the generator-to-panel wiring and ATS installation, utility coordination for any necessary meter work, and permitting through Greendale, WI's building department. We manage the complete project, coordinating the gas contractor, handling all electrical permitting, and ensuring all systems are tested and commissioned before the project is closed. Pair your generator with our panel upgrade services if your panel needs updated connection points, or our surge protection services for comprehensive power resilience in your Greendale, WI home.
Why Choose Us
Generator installation involves more coordination than most electrical projects. Our Greendale, WI team manages every component, from load sizing to final commissioning.
We calculate your Greendale, WI home or business's actual generator load requirement based on real appliance data and your specific backup power priorities. This prevents the common mistake of purchasing an oversized generator that wastes installation budget, or an undersized unit that trips under realistic load during an outage.
The automatic transfer switch is the most critical component in a standby generator installation. We specify and install code-compliant, manufacturer-matched ATS units that are rated for your generator's output and your panel's service size, with proper utility-side disconnection that protects both your equipment and utility lineworkers during an outage.
Generator installation involves electrical, gas, and sometimes civil work (for the pad). Our Greendale, WI team coordinates the complete project, scheduling the gas contractor, managing the building and mechanical permit applications, and orchestrating the installation sequence so every trade completes their scope without creating delays for others.
We are trained installers for major standby generator brands including Generac, Kohler, Briggs & Stratton (Standby Power), and Cummins. Manufacturer-certified installation is required for warranty validity on most standby generator systems, protecting your Greendale, WI investment for the long term.
Generator installation in Greendale, WI requires building permits, gas permits (through the gas contractor we coordinate), and in some cases utility notification. We manage all permitting paperwork and attend all required inspections, providing you with a complete closed-permit package at project completion.
Before we hand over any generator installation in Greendale, WI, we conduct a full-load test, simulating an outage, verifying the ATS transfers correctly, confirming the generator powers all specified circuits under real load, and documenting the transfer time and output voltage. We also register your warranty and walk you through the maintenance schedule before we leave.
Our Process
Generator installation is a multi-phase, multi-trade project. Here's exactly how our Greendale, WI team manages every phase from initial consultation to first automatic outage test.
We visit your Greendale, WI property, conduct a load analysis of your home or business electrical system, identify your backup power priorities, and calculate the generator capacity needed to support them reliably. We present sizing options with honest tradeoff analysis, not just the most expensive option.
We assess the proposed generator pad location for code-required setbacks from windows and openings, gas line routing options, conduit routing from the generator to the panel, and ATS placement. We document the complete installation layout for the permit application.
We submit the building and electrical permit applications to Greendale, WI's building department and coordinate with a licensed gas contractor for the gas line scope. We provide the gas contractor with our electrical installation timeline to ensure both scopes are completed in the correct sequence.
We prepare or coordinate preparation of the generator's mounting pad, receive and position the generator unit, and complete the pad mounting according to manufacturer specifications. Generator placement follows all required setbacks from structures and openings in your Greendale, WI property.
We install the automatic transfer switch at the panel location, run the generator-to-ATS wiring in appropriate weatherproof conduit, make all connections at both ends, and complete all panel modifications required for the ATS integration in your Greendale, WI home or business.
After the gas contractor completes the gas connection, we commission the generator, starting it, testing ATS transfer function under simulated outage, running a full-load test, and verifying all specified circuits power correctly. We register your warranty, set up the remote monitoring app if applicable, walk you through the maintenance schedule, and provide complete permit documentation before we close the project.
