In one example, a method of testing a power distribution system including a first circuit protection device and a second circuit protection device coupled to the first circuit protection device downstream of the first circuit protection device is described. The method includes monitoring a status of a communicative connection between a ZSI output port of the first circuit protection device and a ZSI input port of the second circuit protection device with a ZSI monitor of the first circuit protection device, detecting whether the ZSI output port of the first circuit protection device is coupled to the ZSI input port of the second circuit protection device, and indicating the status of the communicative connection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power distribution systems and methods of monitoring zone selective interlocking in a power distribution system","description":"Power distribution systems and methods are described.
