Product FAQs
6 answersWhich load centers are compatible with the Q3020 tandem breaker?
This breaker is designed for use in Siemens, EQ, Ultimate, PL Series, and ES Series load centers that accept QT type tandem breakers. The panel must have notched bus bars to accommodate the CTL rejection clip.
Is the Q3020 a CTL or non-CTL circuit breaker?
The Q3020 is a CTL (Circuit Total Limiting) breaker. It features a rejection clip that prevents installation in panel slots not specifically designed for tandem breakers. For older, pre-1968 panels without notched bus bars, a non-CTL breaker like the Q3020NC is required.
How much panel space does this tandem breaker require?
The Q3020 provides two independent single-pole circuits (one 30A and one 20A) while occupying only a single 1-inch space in the load center.
Can the Q3020 replace legacy Murray tandem breakers?
Yes, Siemens QT series breakers are the manufacturer-approved replacements for legacy Murray MP-T series tandem breakers. The Q3020 is the direct replacement for the Murray MP3020.
Can the Q3020 be used in RV electrical panels?
Yes, the Q3020 is commonly used in RV electrical systems and power centers, such as those made by Parallax Power Components, provided the panel is designed to accept Siemens CTL type QT breakers.
Is this breaker rated for continuous loads?
Standard miniature circuit breakers like the Q3020 are rated for continuous loads up to 80 percent of their maximum amperage rating, unless specifically marked for 100 percent continuous operation.
