Buying Guide

Key purchase considerations help match a transfer switch to your needs. Consider these perspectives:

  • Power capacity and circuits: Align the switch’s amperage and circuit count with your generator’s output and your home’s essential loads. Oversizing offers future flexibility but adds cost and space needs.
  • Indoor vs outdoor installation: Outdoor units require weather-resistant enclosures (NEMA ratings) and corrosion resistance. Indoor units are simpler but require enclosure planning for wire routing.
  • Manual vs automatic operation: Manual switches are affordable and straightforward, while automatic options offer hands-free power transfer but are more complex and expensive.
  • Installation simplicity: Look for kits with included inlet boxes, cords, and clear wiring diagrams for safer DIY setups or for safer professional installation.
  • Durability and materials: Galvanized steel enclosures and quality aluminum connections reduce corrosion and extend service life in harsher climates.
  • Code compliance and approvals: UL/CSA/ETL listings indicate adherence to safety standards suitable for American homes and local code requirements.
