Job Description

Key Responsibilities

Produce and maintain the full electrical drawing set for material handling systems, organized to the standardized sheet-order taxonomy. Specific deliverables include:

Power Distribution & Single-Line Diagrams

• Develop power distribution drawings and single-line / three-line diagrams for 3-phase 480/600 VAC, 120 VAC control power, and 24 VDC distribution.

• Size and document feeders, branch circuits, overcurrent protection, disconnects, and panel schedules in coordination with the responsible electrical engineer.

• Capture load data and distribution hierarchy from power panels through VFDs, enclosures, and field devices.

Permit Drawings & Submittal Packages

• Prepare permit-ready drawing sets and submittal packages for review by the Authority Having Jurisdiction (AHJ).

• Incorporate applicable code references and specification revisions, and support design engineers through permit comment resolution and resubmittals.

Electrical Device, Power & Receptacle Layouts

• Create system layout drawings showing electrical device placement, power layouts, and receptacle layouts overlaid on the equipment / conveyor layout.

• Position panels, control enclosures, disconnects, and field devices in accordance with clearance, access, and mounting requirements.

E-Stop & Safety Zone Layouts

• Draft e-stop layouts and safety zone drawings that clearly define control areas, safety zones, and the devices assigned to each zone.

• Represent e-stop zoning, pull-cords, interlocks, and guarding consistently with the safety design and zone naming conventions.

I/O Connection Schematics & PLC Connections

• Produce I/O connection drawings and PLC connection schematics detailing inputs, outputs, terminations, and device wiring.

• Apply consistent conductor and I/O termination designations across the drawing set to support installation and troubleshooting.

Network Routing & Architecture

• Develop network layout and architecture drawings covering IPC / PLC / HMI distribution and controls / low-voltage network cabling routes.

• Document fieldbus and industrial Ethernet topology (e.g., EtherCAT, Ethernet/IP, vendor networks) and cable routing between control nodes.

Device Typicals, Installation Details & Interlocks

• Create and maintain device typicals, installation / mounting details, and standardized wiring typicals for reuse across projects.

• Document cross-system and cross-vendor equipment interlock details and integrated sub-system connections (scanners, scales, singulators, etc.).

Drawing Standards, Nomenclature & Revision Control

• Follow the established electrical drawing standards for sheet order, title pages, index/sheet lists, legends, references, and nomenclature so sets are uniform across the network.

• Manage drawing revisions, markups, and redlines; maintain accurate revision history and incorporate review comments.

• Coordinate with electrical engineers, controls engineers, vendors, and integrators to reconcile and standardize vendor-provided drawings to internal standards.

Required Qualifications

• Experience: 3–5 years of electrical drafting experience, with demonstrated exposure to material handling, conveyor, or sortation systems (or comparable industrial automation).

• Education: Associate degree or technical diploma in Electrical/Electronics Technology, Drafting & Design (CAD), or a related field — or equivalent demonstrated experience.

• AutoCAD Electrical: Proficiency in AutoCAD Electrical, including project/drawing management, panel and schematic tooling, catalog/wire numbering, and report generation.

• Drawing types: Proven ability to independently produce power distribution drawings, single lines, permit drawings, device layouts, e-stop zoning, I/O schematics, network routing, and device/install typicals.

• Standards discipline: Experience working to a defined drawing standard — consistent sheet order, nomenclature, legends, and revision control.

• Codes: Working familiarity with electrical code and industrial machinery standards (e.g., NEC/NFPA 70, NFPA 79) as they apply to drawing content and documentation.
