Generator Installation FAQ

  • Do I need a transfer switch for a portable generator?

    Yes. A manual transfer switch or panel interlock is required to safely connect a portable generator. It prevents dangerous backfeed, protects utility workers, and allows you to power selected home circuits directly.

  • How big of a standby generator do I need?

    Generator size depends on your home’s load calculation and whether you want to back up the whole house or just essentials. Most homes use a 14kW–24kW standby generator. We provide a free load analysis to recommend the right size.

  • Do you handle permits and inspections?

    Yes. Matrix Electrical Services manages all permits, inspections, and utility coordination required for your generator installation, ensuring it’s fully code-compliant.

  • What’s the difference between an automatic and manual transfer switch?

    A manual transfer switch requires you to flip a switch to restore power with a portable generator. An automatic transfer switch (ATS) instantly detects outages and powers your home with a standby generator — no action required.
