Electrical Design Engineer: Wiring Diagrams Course

Lesson 1 • Electrical Drawing Types Overview

Distinguishes schematic, wiring, and block diagrams by purpose and content. Clarifies when each drawing type is appropriate within a design project.

Lesson 2 • Safety Principles for Design Engineers

Covers hazard identification, protective device logic, and safe design practices embedded in wiring documentation. Connects safety requirements directly to drawing decisions.

Lesson 3 • Industry Standards and Terminology

Introduces standardised naming conventions, abbreviations, and regulatory frameworks used in professional electrical documentation. Ensures consistent communication across design teams.

Lesson 1 • Title Blocks and Drawing Metadata

Covers required fields in title blocks, revision tracking, and approval signatures. Ensures drawings meet professional documentation and traceability requirements.

Lesson 2 • Standard Electrical Symbol Libraries

Introduces internationally recognised symbol sets for passive components, sources, and switching devices. Builds the visual vocabulary required for all subsequent drawing tasks.

Lesson 3 • Control and Protection Device Symbols

Covers symbols for contactors, circuit breakers, fuses, and protective relays used in control wiring. Connects symbol selection to device function and protection logic.

Lesson 4 • Reference Designators and Annotations

Explains alphanumeric tagging of components, terminal blocks, and signal references. Enables cross-referencing between drawing sheets and equipment lists.

Lesson 1 • Extracting Data from Wiring Diagrams

Teaches how to compile wire lists, terminal schedules, and component counts directly from drawings. Produces the structured data needed for procurement and installation.

Lesson 2 • Interpreting Multi-Sheet Diagrams

Covers sheet-to-sheet cross-references, continuation markers, and global signal nets. Enables engineers to navigate large drawing sets without losing circuit context.

Lesson 3 • Tracing Power and Control Circuits

Teaches a structured path-tracing method for following current flow through power and control sections. Builds the analytical habit required for troubleshooting and verification.

Lesson 1 • Translating Requirements into Schematics

Covers the process of converting functional specifications and load lists into schematic topology. Bridges the gap between engineering intent and graphical representation.

Lesson 2 • Schematic Clarity and Readability Rules

Applies layout principles such as signal flow direction, spacing, and grouping to maximise diagram clarity. Reduces interpretation errors during installation and maintenance.

Lesson 3 • Control Circuit Schematic Design

Covers design of start-stop, interlock, and sequencing control circuits using relay logic. Develops the ability to implement control requirements as correct schematic circuits.

Lesson 4 • Schematic Review and Verification

Introduces peer review checklists, design rule checks, and simulation-based verification methods. Ensures schematics are correct before release to wiring diagram production.

Lesson 1 • From Schematic to Wiring Diagram

Explains the translation process from schematic topology to physical wiring connections. Establishes the logical link between design intent and installation instructions.

Lesson 2 • Terminal Block and Interconnection Design

Teaches terminal block selection, grouping by function, and interconnection wiring between sub-assemblies. Enables clear, testable interfaces between panels and field devices.

Lesson 3 • Panel Layout and Component Placement

Covers enclosure sizing, DIN rail arrangement, and component placement rules for control panels. Produces panel layout drawings that support efficient wiring and maintenance.

Lesson 4 • Wire Routing and Duct Fill Calculations

Covers wire routing paths, duct sizing, and fill ratio calculations for control panel wiring. Prevents overcrowding and ensures maintainability of completed panels.

Lesson 1 • Electrical CAD Environment Setup

Covers project configuration, template creation, and symbol library management in electrical CAD tools. Establishes a consistent, reusable drawing environment for all project work.

Lesson 2 • Schematic Drawing in CAD

Teaches symbol placement, wire routing, and net assignment within the CAD environment. Produces electrically intelligent schematics that support automated report generation.

Lesson 3 • Drawing Revision and Change Management

Explains revision numbering, change cloud markup, and controlled release procedures within CAD. Maintains drawing integrity and traceability throughout the project lifecycle.

Lesson 4 • Automated Report Generation

Covers extraction of wire lists, BOM, and terminal schedules directly from CAD drawing data. Eliminates manual data entry errors and accelerates documentation delivery.

Lesson 1 • Instrumentation Loop Diagrams

Covers loop diagram structure, instrument tagging, and signal type annotation for process instrumentation. Enables field technicians to install and calibrate instruments from the diagram alone.

Lesson 2 • Current Transformer and Voltage Transformer Wiring

Covers CT and VT secondary circuit wiring, polarity marking, and burden calculations. Ensures protection relay inputs receive accurate, correctly phased measurement signals.

Lesson 3 • Protection Relay Wiring Diagrams

Teaches wiring of relay input, output, and communication terminals for overcurrent and differential protection. Produces relay wiring diagrams that support commissioning and testing.

Lesson 4 • PLC and DCS I/O Wiring Design

Explains I/O module selection, field device wiring, and common and shield connection practices. Produces I/O wiring diagrams that minimise noise and simplify commissioning.

Lesson 1 • Compliance Verification Against Standards

Teaches verification of drawings against applicable wiring, protection, and equipment installation standards. Ensures the design meets regulatory and client technical requirements.

Lesson 2 • Factory Acceptance Test Documentation

Covers preparation of FAT test procedures, wiring check sheets, and functional test records linked to diagrams. Provides the evidence base for client acceptance of completed panels.

Lesson 3 • Internal Design Review Process

Covers structured review stages, checklist development, and comment resolution workflows for wiring diagrams. Catches errors before external submission and reduces costly rework.

Lesson 4 • Drawing Package Deliverable Management

Covers document register maintenance, transmittal tracking, and client comment response for full drawing packages. Ensures professional, auditable project documentation delivery.
