Circuit Panel Heavy Ups

Keep tripping your breaker? It might be time for a heavy up! One of the most common culprits of a tripped circuit breaker is simply that your circuit is overloaded. Older homes in Maryland sometimes aren’t equipped to handle a typical family’s increased electrical demand. When you use more electricity than your circuit breaker can handle, your system will trip to avoid the hazards that come from an overload, such as an electrical fire.

This problem can be easily remedied with a circuit panel upgrade (called a heavy up) from the electricians at GAC Services. A heavy up increases the electrical capacity your home can handle. Our electricians can help you determine an appropriate amount of amperage for your home and what size panel you will need to accommodate it.

While tripped circuit breakers are one reason to consider a heavy up, if you’re adding an addition to your home, you will also need to consider a larger circuit panel to handle the addition’s increased electrical load. We also offer circuit breaker replacement.

Dedicated Circuitry

A dedicated circuit is used for a single appliance only so it has its own breaker in your electrical box. By giving the major appliances in your home a dedicated circuit, you ensure that these appliances have access to the energy they need without overloading your system.

At GAC, we install and service dedicated circuits for:

  • 120 volt appliances
  • 240 volt appliances
  • Electric car chargers
  • HVAC equipment
  • Hot tub wiring
  • Etc.
