Electrical AutoCAD Basics for Beginners – Episode 6: Wire Numbers, Tags & Cable Schedules (Updated June 2026)
Trust me — every electrical engineer who has ever been handed a poorly-numbered panel drawing knows exactly what it costs: hours of fault-finding, wrong wire connections, and rework after commissioning. Wire numbers and component tags are not administrative overhead — they are the safety and traceability backbone of every panel. NASSCOM-Deloitte's projection of 1.25 million automation professionals needed by 2027 includes thousands of roles specifically in electrical documentation and panel build support. Episode 6 of our Electrical AutoCAD Basics series covers the three documentation skills that make you valuable beyond just drawing: wire numbering schemes, intelligent component tagging, and auto-generated cable schedules.

Why Wire Numbers and Tags Matter More Than Most Engineers Think
A wire number is not just a label — it is a legal identifier. In panel manufacturing, every wire leaving the panel must be traceable via its number in the wiring schedule and back to the schematic. A missing wire number on a live panel can mean a 12-hour shutdown while maintenance staff trace 50 unlabelled wires manually. In AutoCAD Electrical, wire numbers are not labels — they are intelligent properties linked to wire type, cross-section, voltage level, and destination terminal. When you change a wire number, ACE propagates that change to the from-to table, the terminal schedule, and the panel report in one action.
Setting Up Wire Numbering Schemes in AutoCAD Electrical
In your ACE project, go to Project Properties → Drawing Properties → Wire Numbering. Choose your scheme: Sequential (all wires numbered 1, 2, 3... project-wide), Rung-based (each rung gets its own sub-number: 101, 102 for rung 1; 201, 202 for rung 2), or User-defined (custom prefix + number). For manufacturing plants in Pune that follow IEC 60204 standard, rung-based numbering is the most common format. Once set, click Edit → Wire Numbers → Tag All to auto-number every wire in the project in one action. Here is what saves time: when you add a new rung or delete a wire, just run Tag All again — all numbers update to maintain sequence without gaps.
| Documentation Type | ACE Feature | What It Generates |
|---|---|---|
| Wire Numbers | Edit → Wire Numbers → Tag All | Sequential or rung-based wire IDs |
| Component Tags | Project → Retag Components | KM1, KA2, KT3 format tags |
| Tag Audit | Project → Drawing Audit | Flags duplicate or missing tags |
| Cable Insertion | Schematic → Cable → Insert Cable | Multi-core cable with tracked cores |
| Cable Schedule | Reports → Cable Schedule | From/to table, cores, cross-section |
Managing Component Tags: Auto-Tag, Renumber, and Audit
Component tags in ACE follow the format: Type + Number, e.g., KM1 (contactor 1), KA2 (auxiliary relay 2), KT3 (timer 3), SB4 (pushbutton 4). To auto-tag all components in a project, go to Project → Retag Components → select All Drawings → choose your tag format. ACE retags every component in sequence. To audit for duplicate tags (a common problem when merging drawings from different engineers), use Project → Drawing Audit → Check for Duplicate Tags. ACE flags all duplicates and lets you resolve them one by one. This audit function alone saves 2–3 hours of manual checking on a typical 30-sheet project.
Generating Cable Schedules Automatically from Your Project
A cable schedule lists every multi-core cable in the project: cable number, from-equipment, to-equipment, number of cores, cross-section, and colour code. In ACE, you create cables via Schematic → Cable → Insert Cable. Assign a cable tag (e.g., W101 for a 4-core 2.5mm² cable from MCC to Motor-1). ACE tracks all cores through the schematic automatically. To generate the schedule, go to Reports → Cable Schedule. The output is a formatted table ready to be placed on a drawing sheet or exported to Excel. Panel builders and commissioning engineers use this cable schedule on site — it tells them exactly which cable to pull, how many cores to terminate, and at which terminal.

FAQs
What does Electrical AutoCAD Episode 6 cover?
Episode 6 covers wire numbering scheme setup (sequential, rung-based, user-defined), intelligent component tag assignment and auditing for duplicates, cable insertion with tracked cores, and auto-generating cable schedules that list from/to equipment, core count, cross-section, and colour code. These documentation skills are required for panel build coordination, commissioning, and electrical design roles at Tier-1 manufacturers across Maharashtra.
How does AutoCAD Electrical handle wire numbering automatically?
AutoCAD Electrical automatically assigns wire numbers to every wire segment based on your chosen numbering scheme — sequential or rung-based. When you run Edit → Wire Numbers → Tag All, all wires in the project receive numbers in one action. If you add or delete rungs, running Tag All again renumbers the entire project instantly, maintaining sequence without gaps. Component tags are similarly auto-assigned via Project → Retag Components. The project-wide consistency is what makes ACE documentation audit-ready for ISO and IEC compliance.
What salary does an electrical documentation engineer earn in Pune?
Based on PayScale, Glassdoor, and AmbitionBox data (2025–2026): Electrical Draftsmen or Documentation Engineers earn ₹2.8–3.8 LPA fresher in Pune. Electrical Design Engineers with complete ACE documentation skills earn ₹4.5–7 LPA. Panel Build Coordinators at Tier-1 suppliers earn ₹3.5–5.5 LPA. Technical Documentation Specialists at Siemens or Bosch Pune earn ₹6–9 LPA. These figures reflect mid-2026 hiring data from the Pune manufacturing corridor.
