Product FAQs
6 answersWhich panelboards are compatible with the Siemens EE1B020 circuit breaker?
This bolt-on breaker is designed for installation in Siemens FC, FE, CDP, P2, and P3 panelboards. Always verify your specific panel labeling to ensure proper fitment and UL compliance.
What wire sizes and materials do the lugs on the EE1B020 accept?
The factory-installed lugs accommodate 14 to 10 AWG copper (Cu) conductors and 12 to 10 AWG aluminum (Al) conductors.
Is the EE1B020 rated for direct current (DC) applications?
Yes, while primarily used in 120VAC systems, this breaker is also rated for 125VDC applications, providing a 5kA interrupting capacity for direct current circuits.
Can the Siemens EE1B020 replace older ITE or Gould EE frame breakers?
Yes. Because Siemens acquired ITE and Gould, the EE1B020 serves as a direct replacement for legacy ITE and Gould EE frame breakers with matching 20A, 1-pole specifications.
What is the modern replacement for the legacy EE1B020 breaker?
The EE1B020 is a legacy E-frame component. In many modern applications, it has been superseded by the Siemens ED21B020, though the EE1B020 is still widely used to maintain existing equipment.
Does the EE1B020 plug in or bolt on to the panel bus?
This model features a bolt-on connection type. It must be securely fastened to the panelboard bus with screws, unlike standard plug-on residential breakers.
