Bypass switches with or without isolation are permitted; they carry a continuous and withstand rating compatible with the transfer switch (UPS static bypass switches may instead be rated for all connected loads from either source) and are designed for emergency service as factory assembled and tested apparatus.
This control maps to 2 controls across 2 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 2 it maps to, and the evidence behind each claim, over MCP and REST.
