The main electrical panel is one of the most important aspects of any home. It is responsible for gathering electricity from the local provider, and distributing it safely to the active circuits throughout the house. Each panel is designed with a maximum limit of breakers or branch circuits that can be added. When performing a home inspection, we note when panels are completely full of breakers and they are “At Capacity.” So what happens when the panel reaches its capacity?<\/p>\n

What Happens When My Electrical Panel Is At Full Capacity?<\/h2>\n

When a panel is at full capacity, there simply aren’t any more slots left in the panel to add any more circuits. The more appliances and devices that are in use in the house, the more power is being drawn from the panel, and the more circuits are needed. Most modern residential panels are designed to draw 100 – 200 amps of electricity.<\/a> This is quite a bit of power and lots of branch circuits can be connected. However, if the main panel is out of slots, nothing can be added in the future and it also indicates that you may be drawing a lot of power off of your panel.<\/p>\n

During our standard home inspections, we always take a good look at the electrical panel. We will be sure to note if all breaker slots are being used (as show in the picture below). When all breakers are occupied, we will note in the report that the panel is at capacity.<\/p>\n

But just because all circuits are occupied, that does not necessarily mean that the panel is being overloaded. This is because, generally, not all circuits are being used to their fullest potential. You might have one circuit that is only servicing one low wattage lightbulb, and another that services several unused outlets. Overloading your panel is a problem and can cause your main breaker to trip. However, there is no good way to test for this during a home inspection.<\/p>\n

So it is usually not a big problem if we do identify a panel at full capacity. Well, not unless you are looking to add additional circuits. Or if the electrical panel is showing symptoms of an overload.<\/p>\n

What Are the Solutions to an At Capacity Panel?<\/h2>\n

Say your electrical panel is at full capacity – all available circuits are occupied. What happens if you want more circuits? There are two main options.<\/p>\n
