Appliance & Equipment Circuits

A dedicated circuit serves a single appliance or piece of equipment without sharing capacity with anything else on the panel. This is required for many major appliances and recommended for others to prevent overloaded circuits and nuisance breaker trips.

Common Applications:

  • Refrigerators and freezers

  • Microwaves and kitchen appliances

  • Washing machines and laundry equipment

  • Sump pumps

  • Air conditioning units

  • Workshop and garage equipment

Garage & Workshop Circuits

Garages and workshops often demand more power than standard household circuits provide, particularly when running tools, compressors, or equipment with higher amperage requirements. We install circuits sized to the equipment in use, with consideration for future additions where applicable.

Basement Circuits

Whether finishing a basement or adding equipment to an unfinished space, we install the necessary circuits to support lighting, outlets, and appliances while meeting current code requirements for the space.

Identifying the Need for a Dedicated Circuit

Frequent breaker trips, an appliance that underperforms, or a circuit shared by too many devices are common indicators that a dedicated circuit is needed. We assess the existing setup and determine the appropriate solution based on the equipment involved and your panel's available capacity.
