# IA: CNC install complaint — tools/materials/cable sizing (STG)

**Thread:** `1974070585abe02c` | **Client:** STG Contractors shereen@stgcontractors.co.za → april@/tessa@
**Date:** 2025-06-05 (install scheduled 04/06/2025)

## Issues raised
- No confirm despite client chasing 02–03 Jun; techs call morning-of.
- Techs unprepared (no drill); client drove for materials; materials list same day.
- Pre-site only flagged isolator; air/other points incomplete.
- Client installed 16mm² armored; machine-to-isolator connection 6mm — questions logic.

## Rule
- Pre-install checklist (tools, isolator, air, cable sizing) before day-of.
- Confirm appointment in writing; send materials list ahead.
- Keep as IA/complaint — not a paid CRM stem by itself.
