Generator Installation in Boise, ID
Protect your family and home from unexpected power outages. Automatic standby generators from Generac, Kohler, and Cummins, plus cost-effective manual generator interlock kits across Ada County.
Why Boise Homes Need Standby Emergency Power
From severe sub-zero winter cold snaps freezing municipal water pipes to summer heatwaves overloading the electrical grid, Boise homeowners face increasing blackout threats.
Never Backfeed a Generator Without an Interlock or Transfer Switch
Plugging a portable generator directly into a dryer outlet (backfeeding) sends lethal high voltage backward into neighborhood power lines, endangering utility linemen working to restore the grid. An automatic transfer switch or code-approved mechanical interlock is legally required by Idaho law.
Prevent Frozen & Burst Pipes
During sub-zero Boise winter freezes, a power failure shuts off your home furnace blower. Within hours, indoor temperatures drop, causing copper pipes to burst and flood basements.
Refrigeration & Food Security
Keep refrigerators and chest freezers operating continuously through multi-day outages, protecting hundreds of dollars in groceries and perishable medication like insulin.
Medical Equipment Uptime
If someone in your home depends on CPAP machines, oxygen concentrators, or motorized mobility equipment, uninterrupted backup electrical power is non-negotiable.
Work-From-Home Continuity
Maintain home office connectivity, computers, servers, security systems, and Wi-Fi routers through grid failures without missing a beat.
Comprehensive Generator Solutions in Boise, ID
From automatic natural gas standby units to portable generator inlet hookups and automatic transfer switch integration.
1. Whole-Home Automatic Standby Generators (14kW–26kW)
A whole-home standby generator provides seamless, hands-free emergency power. Plumbed directly to your home's natural gas line or an on-site propane tank, it continuously monitors grid health and starts automatically within seconds of a power disruption.
We are certified installers for top brands including Generac Guardian, Kohler RCA, and Cummins QuietConnect. We calculate your home's starting and running wattage, pour an engineered equipment pad, and complete all electrical and fuel connections with municipal permit sign-offs.
- Generac, Kohler, and Cummins authorized turnkey installation
- Piped to natural gas (Intermountain Gas) or liquid propane (LP)
- Engineered weather-resistant composite or concrete equipment pads
- Mobile-link Wi-Fi monitoring delivering status alerts directly to your phone
2. Automatic Transfer Switch (ATS) Main Panel Integration
The Automatic Transfer Switch (ATS) is the brain of your standby generator system. It safely isolates your home electrical circuits from the utility grid, ensuring generator power never backfeeds into Idaho Power lines while feeding electricity to your home.
We install service-entrance-rated 100A, 200A, and 400A automatic transfer switches equipped with smart load management. If your central air conditioner and oven kick on simultaneously, the ATS manages the load priorities to prevent generator stalling.
- 200-Amp service-entrance rated Automatic Transfer Switches
- Smart electrical load shedding modules for high-tonnage AC units
- Safe utility isolation preventing lineman hazard backfeeding
- City of Boise electrical inspection and utility coordination
3. Portable Generator Interlock Kits & Power Inlets
If a full automatic standby generator is outside your budget, a manual generator interlock kit offers an affordable, code-compliant alternative for powering your entire breaker panel using a portable gas or dual-fuel generator.
We install an exterior weatherproof 30-amp or 50-amp power inlet box (CS6375 or L14-30P) on your home exterior and route heavy conductors to your breaker panel. A custom mechanical interlock plate prevents the generator breaker and main utility breaker from ever being turned on simultaneously.
- Code-compliant panel interlock bracket custom-fitted to your panel
- 30A (7,500W) or 50A (12,000W) weatherproof exterior inlet box
- Elimination of hazardous, tangled extension cords through doorways
- Full control over which household breakers to power during an outage
4. Natural Gas Meter Coordination & Permitting
A whole-home generator requires an adequate volume of natural gas (CFH - cubic feet per hour) to run at full load. In many cases, Intermountain Gas must upgrade the home gas meter to a high-capacity 2-lb or 400 CFH meter to supply both your furnace and generator simultaneously.
We handle complete turnkey coordination: pulling city electrical and mechanical permits, calculating gas volume requirements, installing heavy-wall black iron pipe, and arranging city inspections for official utility sign-off.
- Gas meter volume calculations and Intermountain Gas coordination
- Rigid black iron or corrugated stainless steel (CSST) gas piping
- Strict compliance with NFPA 54 fuel gas codes and window clearances
- Final municipal electrical and plumbing permit sign-off

Common Questions About Boise Generator Installation
Everything you need to know about whole-home standby power and transfer switches in Ada County.
A standby generator is permanently installed outside on a concrete pad and piped to your home's natural gas (Intermountain Gas) or propane supply. Connected to an Automatic Transfer Switch (ATS), it monitors grid voltage 24/7. When Idaho Power service drops out, the ATS signals the generator to start, reaches operating frequency within 10 to 20 seconds, and safely transfers household electrical loads automatically—even if you are away on vacation.
For essential circuits (refrigerator, furnace blower, sump pump, lights, Wi-Fi, and medical equipment), a 10kW to 14kW generator is sufficient. For whole-house coverage including central air conditioning, electric range, water heater, and well pumps, a 20kW to 26kW unit (such as a Generac Guardian or Kohler 26RCA) is recommended. An electrician performs a peak load calculation to size the unit precisely.
A complete whole-home automatic standby generator package in Boise typically ranges from $7,500 to $14,000, which includes the 18kW–24kW generator unit, 200A automatic transfer switch, concrete pad, electrical wiring, gas piping connection, City of Boise electrical and mechanical permits, and initial system commissioning. A portable generator interlock kit installation is significantly more affordable, ranging from $800 to $1,800.
An Automatic Transfer Switch (ATS) is paired with a permanent standby generator and operates autonomously without human intervention within seconds of a blackout. A manual generator interlock kit is a mechanical plate installed on your main breaker panel that allows a portable gas or dual-fuel generator to safely backfeed your home through an outdoor inlet box while physically preventing dangerous utility backfeeding into power lines.
Permanent standby generator installations in Boise require both an Electrical Permit and a Mechanical/Plumbing Permit from the City of Boise Planning & Development Services (or Idaho Division of Building Safety in unincorporated Ada County). The installation must comply with NEC Article 702, national fuel gas codes (NFPA 54), and local municipal property setback ordinances from property lines and bedroom windows.
Yes. Standby generators running on natural gas supplied by Intermountain Gas have a virtually limitless fuel supply and can operate continuously for days or weeks during severe winter storms. Regular oil and filter maintenance is recommended every 100 to 200 hours of continuous runtime.
