Abstract: A multi-pole mounting base for interfacing a circuit breaker and/or circuit interrupter with an electrical panel is disclosed. The electrical panel has an interior configured to receive remote operated circuit breakers (ROCBs) in signal communication with a communication board internal to the electrical panel, non-ROCBs, and ground fault circuit interrupters (GFCls). The mounting base includes a unitary support platform assemblable to the interior of the electrical panel and having first mounting regions with common structure configured to receive any one of the ROCBs, the non-ROCBs, and the GFCls. The support platform also has second mounting regions configured to receive the communication board. The support platform is configured to assemble adjacent to another support platform in the electrical panel.
