What Is a Residential Electrical Subpanel?
Getting to know your home’s electrical system is important. It can help you better communicate with your electrician and, in the case of emergencies, equip you with the knowledge to help get the problem solved quickly – even if that just means contacting your trusted electrical team! By understanding the different components of your electrical system and how they interact with each other, you can be sure you’re using it safely and wisely, all while becoming more familiar with the ins and outs of your home. In this post, we’re going to delve a bit deeper into the land of electrical service panels.
What Is an Electrical Subpanel?
An electrical subpanel (the spelling may vary) is also referred to by electricians as a load center, and is essentially a smaller electrical service panel that works in concert with your home’s main panel, helping to safely distribute electricity in your home. Subpanels are also known as ‘satellite’ service panels because these devices may be located in parts of the home other than where the main panel is installed.
Similar to the main service panel in many respects, subpanels typically contain a smaller number of circuit breaker switches, and normally direct electricity to a specific area or appliance in the home.
Electrical Subpanel Locations
In some cases, a subpanel may be located immediately adjacent to the main service panel. However, subpanels may also be located in closer proximity to where the power is being used. Additions, garages, and detached structures such as a cottage, studio, or workshop are all examples of applications where a licensed electrician may recommend the installation of a satellite subpanel. Basements, garages, mechanical areas, and even closets are common places where the panel may be installed. Depending on the circumstances, a home may even employ more than one electrical subpanel, or none at all in many cases.
Benefits of an Electrical Subpanel
Electrical subpanels are often installed when a home’s main service panel does not have enough space (unoccupied breaker slots in the panel) to accommodate all of the needed new circuit breakers, but otherwise is in good condition and has plenty of electrical load capacity. In other cases, providing quick, easier access to the new breaker switches may also play a role in the process. The decision of when, where, and why to install a subpanel is typically made on the recommendation of the experienced electrician the homeowner is working closely with. In the Denver-Boulder area, Save Home Heat’s electrical team can assist you!
Common Reasons An Electrical Subpanel May Be Installed in Your Home Include:
- Increasing the branch circuit capacity of your electrical system, without having to replace a main service panel that’s in good shape
- Adding new electrical circuits to a home addition
- Adding convenient circuit breaker access – for safety! – for outbuildings such as cottages, studios, workshops, and certain major appliances
Distinguishing Your Subpanel from Disconnect Switches
It’s not surprising to our team that homeowners may confuse an electrical subpanel with certain types of electrical disconnect switches (aka. cut-off switches). While electrical subpanels may be found in a home’s closet, garage, or mechanical area, disconnect switches are more often found close by to items such as a hot tub, an AC system outdoor unit, a permanently installed power tool, or a home lighting control or sprinkler system. Disconnects are normally installed for easy power shutoff access in the case of service, maintenance, or emergency situations. What you see inside a disconnect box is normally simpler than a subpanel, but it’s easy to understand the confusion.
Next time you have an electrical service call, we recommend that you ask your trusted electrician if there are any electrical disconnect switches or subpanels employed in your home and if so, get a quick tutorial on them – that is, only if you feel comfortable ‘going there.’
