Technical Documentation, Standards and Regulatory Compliance
What the exam tests
This domain covers drawings, schematics, P&IDs, datasheets, manuals, work reports, version control, and the standards behind the work. Moroccan practice uses NM standards, commonly applied IEC and NF references such as NF C 15-100 for LV installations and IEC 60204-1 for electrical equipment of machines; confirm the edition required by the site and contract.
Core rules
- Use the correct revision. A drawing marked as-built or approved for construction overrides a superseded installation drawing only when the change is formally recorded.
- Record equipment identity: manufacturer, model, serial number, rating, firmware, and location. Ratings on the nameplate take precedence over a generic datasheet when they differ.
- Reports need date, author, asset, measurement method, units, result, and acceptance criterion. A number without a method or unit is not evidence.
- Standards define minimum safety and performance; they do not replace the manufacturer's instructions or the site's permit system.
- Keep calibration certificates, test sheets, and as-built markups traceable to the asset and work order.
Worked example
A project drawing schedules a 15 kW motor, but the installed nameplate reads 11 kW, 400 V, 21.5 A. The motor is the as-built reality, but the drawing and protection settings must be formally updated. Record the nameplate data, check cable and overload suitability for 21.5 A, and issue a marked-up drawing for approval. Do not silently change the setting and leave the drawing wrong.
Traps
Working from an uncontrolled revision; copying a datasheet value over a nameplate; omitting units; signing a report without a date; and treating a standard as a substitute for manufacturer instructions.
