Mechanical Power Circuit Up Amtech Cb Csa Zs Walk For Selection

Mechanical Power Verification writes to model Public API · not yet exposed

Coming soon

Before you run this

Mechanical-power circuit selected (or one component on it). Amtech-style sizing rules configured for the project. Cable / circuit parameters present on the equipment families.

After it runs

Each circuit component has CB rating, cable CSA and Zs results written; non-compliant circuits flagged with a structured error pointing at the failing rule.

When to use this

Don't use this when

Small-power circuit-up (use the BS 7671 ring/radial command), distribution upstream of the local isolator, or projects where compliance is verified externally in Amtech.

Inputs

NameKindTypeRequiredDefaultDescription
PresetKind config string no "calculation_defaults" Deterministic config preset

Decision flow

1. Read every component on the selected mechanical-power circuit.
2. Pull the FLA, route length and CB type from each.
3. Apply the project's CB / CSA selection rules and compute Zs end-to-end.
4. Write CB rating, CSA and Zs back to every component in one Transaction.
5. Flag any rule failures (Zs over the BS 7671 limit, undersized CSA, etc.) with a structured error.

What you'll see in the chat

on start
I'll walk that mechanical-power circuit and run the CB / CSA / Zs checks now.
thinking
Reading each component, sizing the cable and computing Zs against the BS 7671 limit.
on success
Done — circuit verified. CB {cb_rating}A, cable {csa} mm², Zs {zs} Ω (limit {zs_limit} Ω).
on failure
Couldn't verify the mechanical-power circuit: {error}.
