Electrical Heavy Ups

If you're a property owner, you know the importance of keeping your electrical systems up to date. One of the most important electrical services you may need is a heavy-up, which is an upgrade to your electrical system's capacity. If your home was built 20, 30, or 40+ years ago, your system may not be equipped to handle the new levels of electricity demand in the present day. At Castro Electrical Services, we can provide what is called a “heavy up” where we increase your home's capacity to maintain the levels of electricity your home needs. Located in Gaithersburg, MD we have provided electrical services to Montgomery County, MD since 2011.

What is an electrical heavy up?

An electrical heavy up is a process of upgrading the electrical service panel of a building or property to increase its capacity. This is done by adding a larger main circuit breaker and larger service cables to accommodate the additional electrical load. Heavy ups are commonly performed in older homes or commercial buildings that were not designed to handle the electrical demands of modern appliances and technology. The main reasons for a heavy up are to increase the electrical capacity, improve safety, and meet building codes.

The three most important pieces of information regarding electrical heavy ups are:

  • Heavy ups increase the capacity of the electrical service panel.
  • They are commonly performed in older buildings.
  • Heavy ups are done to improve safety and meet building codes.

Common Signs You May Need a Heavy Up

If your property is experiencing electrical issues such as circuit overloads or tripped breakers, it's likely that your electrical system is not capable of handling your power needs. A heavy-up service can solve these issues by increasing your electrical system's capacity.

The three most important pieces of information regarding why a property owner may need an electrical heavy up are:

  • The existing electrical service panel may be insufficient to meet the electrical demands of the property.
  • New appliances or technology may require more electricity to operate.
  • A heavy up may be required to meet building codes after renovations or additions.

What is involved in an electrical heavy up?

An electrical heavy up involves several steps. The first step is to evaluate the existing electrical service panel to determine if it can accommodate the required upgrades. If the existing panel is not suitable, a new panel will need to be installed. The next step is to remove the existing panel and install the new one. This includes running larger service cables to the panel and installing a larger main circuit breaker. Once the new panel is installed, the electrician will need to test and certify the installation to ensure that it meets safety standards and building codes. Our team at Castro Electrical Services can provide and analysis of your current system and complete the heavy-up services you need to get your property running efficiently.
