![]() The proviso is that the total amps on both circuits do not exceed 80% combined load of the breaker amperage. This configuration allows connection to two circuits. If the panel allows for more circuits than circuit breakers, a certain number can be tandem breakers. This rating means that the panel can have 20 circuit breakers but a total of 24 branch circuits. The rating of other panel boxes could be with a 20/24 designation. For example, a 100-Amp service panel box may limit you to a total of 20 circuits and thus a maximum of 20 circuit breakers. There is a link between the rated number of circuits of a panel and the number of amps the panel can handle. Manufacturers make electrical panels in different sizes for different applications, which results in a varying maximum number of breakers, depending on the panel’s rating. Therefore, the circuit panel manufacturer will indicate the maximum number of permitted circuit breakers for fitment in the electrical service panel. Article 408.54 of the NEC is where you can find this prescription deferring to the manufacturer’s instructions. ![]() The new specification is that the number of circuit breakers installed must not exceed the designed number of breakers the panel board can hold. Since 2008, the NEC no longer stipulated a maximum number of circuit breakers. ![]() Historically, the number of overcurrent devices or circuit breakers allowed in an electrical panel was controlled and regulated by the NEC to be no more than 42 breakers. How Many Breakers Are Allowed In A Panel? Let’s take a look at what the restriction is so that you keep your home within code. Knowing what these maximums are is crucial information you need when planning any extensions or additions to the electrical system in your home. ![]() The design of these panels is to contain a specific number of breakers. Manufacturers make different sized electrical panels for different applications in the home. Panel Rating Number of Spaces/Slots Number of Individual Circuits 200 amp 40 80 150 amp 30 60 100 amp 12 24 The number of breaker spaces and circuits vary by manufacturer The main disconnect size must comply with the panel rating. Manufacturers rate their panels and limit the number of electrical circuit breakers based on that rating. 120v single-pole breakers will use 1 breaker slot, while 240v double-pole breakers will use 2 breaker slots. Most 200 amp panels will have 40 breaker slots but can accept more circuits with tandem breakers. The number of circuits and breakers you can install in an electrical panel is limited by the panel’s design. So how many breakers can electric panels support? The NEC previously regulated the maximum number of breakers an electrical panel can have, but this has changed over the years.
