Expand Your Home’s Electrical Capacity Safely

A sub panel is a great solution when you need more circuits, are adding new equipment, or want to support an expansion or renovation. TNB provides professional sub panel installation and upgrades, ensuring your home has the power it needs—safely and efficiently.

What Is a Sub Panel?

A sub panel is a smaller service panel that branches off your main electrical panel. It provides additional circuit capacity without replacing the entire main panel.

Sub panels are ideal for:

  • Home additions or renovations
  • Detached garages or workshops
  • Basements or rental suites
  • Hot tubs, EV chargers, or large appliances
  • Heat pump additions
  • Areas with multiple circuits concentrated in one space

They help distribute electrical load safely and neatly.

Signs You May Need a Sub Panel

Consider adding a sub panel if:

  • Your main panel is full but still in good condition
  • Breakers are doubling-up (tandem breakers installed incorrectly)
  • You’re adding a high-demand appliance (EV charger, hot tub, heat pump)
  • You’re finishing a basement or adding a rental unit
  • You want to organize circuits in a detached building

Adding a sub panel often prevents the need for a full panel upgrade.
