Read a conceptual power-connectivity overlay

Planning workflow

1. Place a conceptual source and name each route segment and endpoint.
2. Connect route nodes deliberately instead of relying on visual overlap.
3. Toggle branches and inspect downstream reachable and unreachable states.
4. Export the network summary as a discussion aid for qualified review.

Formula or decision logic

Treat the overlay as a graph G = (V, E). Starting at source nodes, traverse only enabled edges. An endpoint is shown as connected when it is reachable through that traversal. Demand, capacity, phase, voltage, conductor, overcurrent, and fault behavior are outside this graph unless a future reviewed engineering module explicitly adds them.

Worked planning example

A source connects to junction J1, which feeds lights L1 and L2. Disabling the J1-to-L2 edge leaves L1 reachable and L2 unreachable. The visual state correctly identifies the modeled break; it does not diagnose the physical cause or state that the remaining branch is safe.

Limitations and review boundary

• Reachability is not electrical continuity testing.
• The model omits hidden field conditions and installation details.
• No green route should be interpreted as code-approved or energized safely.
