# evaluate-voltage-topology

`station__power-systems__evaluate-voltage-topology` · external (needs EXECUTION_BACKEND_URL configured) · domain `power-systems` · pv-relevance `non-pv`

Evaluate bus voltage topology for wearable/vehicle power systems. Routes by voltage level and computes wire gauge, insulation weight, motor efficiency, and touch safety. 5 regimes: SELV (<60V) through extreme (>500V).

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.
