Only after passing inspection will the city issue a final approval, allowing the generator to be used legally.

Generator Placement and Environmental Considerations

Proper placement of a generator is crucial for safety, performance, and longevity. Salt Lake City’s cold winters, snow accumulation, and occasional windstorms require careful planning to protect your generator from environmental damage while maintaining safe operation.

Outdoor Placement Requirements

  • Outdoor Installation: Generators must be installed outdoors to prevent carbon monoxide buildup indoors. Indoor installations require specialized equipment and ventilation, which are rarely approved for residential use.
  • Clearances: Maintain a minimum of five feet clearance from all doors, windows, and air intake vents. This distance minimizes the risk of exhaust gases entering the building and reduces fire hazards.
  • Stable Foundation: Generators should be installed on a level, stable surface such as a concrete pad or reinforced gravel bed to prevent shifting or sinking over time.
  • Elevated Placement: In areas prone to snow accumulation or flooding, elevating the generator slightly above ground level helps protect equipment and maintain airflow.
  • Wind and Debris Protection: Consider installing windbreaks or protective enclosures that meet code requirements to shield the generator from high winds and blowing debris without restricting ventilation.

Fuel Storage and Safety

The fuel source—whether natural gas, propane, or diesel—affects generator placement and installation requirements.

  • Natural Gas and Propane: Fuel lines must comply with local plumbing and gas codes, including proper shutoff valves and leak detection mechanisms.
  • Diesel Generators: Require secure, code-compliant fuel tanks located away from ignition sources and with spill containment measures.
  • Fuel Ventilation: Fuel tanks and lines must be installed to prevent buildup of fumes and ensure safe ventilation.

Electrical Connections and Safety Measures

Connecting a generator to your home’s electrical system is a complex task that must be performed according to strict code requirements to prevent backfeeding, electrical shock hazards, and equipment damage.

Transfer Switch Installation

An approved transfer switch is mandatory to safely connect a generator to your home’s electrical panel. Transfer switches isolate the generator power from the utility grid, preventing dangerous backfeed that could injure utility workers or damage equipment.

  • Manual Transfer Switches: Require manual operation to switch power sources.
  • Automatic Transfer Switches (ATS): Detect power outages and automatically switch to generator power, providing seamless backup.
  • Code Compliance: Transfer switches must meet UL (Underwriters Laboratories) standards and be installed per NEC Article 702 and 705 regulations.

Wiring and Grounding Requirements

Proper wiring and grounding are essential for safe generator operation:

  • Licensed Electricians: All wiring must be installed by Utah-licensed electricians experienced with local codes and generator installations.
