What Does BD1520 Breaker Mean?

BD1520 is an Eaton / Cutler Hammer brand miniature molded case circuit breaker. This breaker is a tandem / circuit limiting breaker. In other words, BD1520 is a double circuit breaker that takes up one circuit breaker space on a panelboard. However, it does not have a common trip or handle tie for simultaneous disconnecting of two poles — unlike a two-pole circuit breaker.
