Buying Guide: Key Considerations For Your 200 Amp Main Disconnect

  • Outdoor vs Indoor: Choose a NEMA rating that matches your installation site. Outdoor models require weather resistance and corrosion protection.
  • Main Breaker vs Main Lug: Decide whether you need a built-in main breaker or a main-lug-only panel with separate disconnect options.
  • Space for Expansion: Consider the number of spaces and whether future circuit additions are likely. Convertible or expandable centers offer flexibility.
  • Conductor Compatibility: Check allowed wire sizes and bus materials (tin-plated copper is common for better conductivity).
  • Compatibility With Existing Breakers: Ensure the panel supports the breaker types you plan to install (THQL/THQP, Homeline, etc.).
  • Safety Features: Look for visible ON/OFF indicators, tamper-resistant handles, grounding provisions, and arc-quenching protections where applicable.
  • Installation Flexibility: Removable doors, knockouts, and feed type support (overhead vs underground) can simplify setup.
  • Maintenance Access: A design that allows easy wiring access reduces installation time and errors.
