When it comes to electrical safety, circuit breakers are one of the first things to come to mind. It’s essentially a fail-safe that protects a system from overloading hazards and other electrical faults. However, the cost to design and build one can get quite high, especially as a circuit breaker’s current capacity increases. So how do owners, contractors, and others save money when purchasing circuit breakers?
When it comes to electrical panels, there are two terms to be familiar with: fully rated and series rated. Fully rated panels are breakers rated for the available fault current that is at the terminal of the breaker. These are the more expensive to make, especially as you get higher and higher in fault current.
