In this episode of the Electrical Building Design Show, David Robison and co-host Mark Robison, PE discuss series rated breakers, exploring their significance in electrical engineering and building design, the critical role they play in managing faults, and the unique advantages and trade-offs that come with them.
A Few of the Items Presented Include:
- Series Rating Certification: The manufacturer of the breakers conducts testing and provides certification, specifying that the breakers when working together, ensure the upstream breaker trips first.
- When Not to Use: Series rated breakers are not a good choice in scenarios where you need a coordinated system.
- Regional Considerations: Regional code differences regarding the use of series rated breakers are important and require checking with the authority having jurisdiction.
- And more…
The Bottom Line:
Series rated breakers offer a practical solution for specific scenarios, balancing cost-effectiveness with safety and the unique requirements of each project. That said, the need to weigh advantages and trade-offs requires thought and understanding before proceeding.
In the video below, David and Mark present more detail on series rated breakers and show how these devices offer a practical solution to specific scenarios.
