Why Are Some Breaker Boxes Outside Of Homes? Here's What It Means

The image of a breaker box in your mind probably looks like a small metal box tucked away in a corner of your home. It's the metal contraption with switches that control the flow of electricity throughout your house, so, after all, it makes sense to have it inside. But this is not always the case, as there are breaker boxes found outside, usually mounted on exterior walls of newer homes.

One of the things it's good for new homeowners to know about circuit breaker boxes is that placing these outside makes them easily accessible during emergencies, especially fires that affect houses. Yes, it all boils down to safety and keeping things running smoothly rather than simply to hide the eyesore in your home. In some areas, having the home's breaker box outside is the best option for homeowners, first responders, and utility workers alike. Local regulations and the layout of the home usually determine whether a breaker box gets installed inside or outside. Some building codes require that breaker boxes be mounted outside, especially for homes with specific electrical needs or those in certain climates. In other places, meanwhile, the decision depends on what is more convenient for utility workers who might need quick access to the power supply.

The main reason some breaker boxes are located outside is to comply with electrical codes. These codes exist to ensure that homes and buildings are up to safety standards, and placing the breaker box outside just makes more sense in some cases. Having an outside breaker box is ideal in emergencies when every second counts. The National Electrical Code requires accessible emergency disconnects in certain situations, ensuring first responders can quickly shut off power without entering the home. This is especially critical in places with frequent wildfires or other disasters where fast action can prevent further damage. Exterior placement reduces delays and improves safety for both occupants and emergency personnel. Homes that are part of a new construction project may also have an outside-mounted box because it gives easier access for power companies when they need to disconnect.

Aside from easy accessibility, an outside breaker box is also often a way to manage space, especially in smaller houses. Putting it outside allows for a cleaner and more organized interior, freeing up wall space that might be needed for storage or furniture. This can also simplify future electrical upgrades or maintenance since electricians can work without disrupting the household.

There are several things to consider when it comes to having a breaker box outside your home. For one, having it there means it will be more exposed to the elements. Weather situations like rain, snow, or extreme heat can potentially affect the performance of your electrical system over time. Fortunately, breaker boxes are mostly designed to withstand outdoor conditions. But there is still a chance that exposure to the elements can lead to wear and tear or rust, which would increase the need for more frequent maintenance. 

You might also think about how to best secure your breaker box when it is outside. Its placement, after all, makes it easier for any person to tamper with it. You can install locks on your breaker box, yes, but it's still best to place it in a well-lit and secure area. Keeping it in a more visible or accessible spot could make it an easier target for vandals. Therefore, it may also be a good idea to install a surveillance camera that covers your outdoor breaker box. You definitely don't need to discover firsthand how much it costs to replace your circuit breaker box, especially if you're operating on a tight budget at home. If you're using a lock, just make sure that the key is readily available in case of emergencies.
