Through this role, you will ensure CEL continues to enhance its reputation for building the highest-quality switchgear with support systems that exceed customer expectations.

Scope of Accountability

The Electrical Design Engineer is accountable for the design, documentation and compliance of electrical systems across CEL's LV switchgear product range, including:

• Electrical schematic design for LV switchboard assemblies in accordance with UL standards (including UL891, UL62368-1, UL508A, UL1008S, UL1008, UL67)
• General Arrangement drawing preparation in coordination with Mechanical Design
• Component selection and sizing — ACBs, MCCBs, contactors, relays, protection devices and busbar systems
• Electrical calculations — fault level, load, cable sizing, busbar rating and thermal analysis
• BOM generation and maintenance for all electrical designs
• FAT procedure support and technical documentation preparation
• Control logic, interlocking and communication interface design where required
• Compliance verification against UL standards, NFPA, client specifications and internal quality procedures
• Structured project documentation management
• Familiar with IEC Standards

Electrical Design & Schematics

• Review and interpret client specifications, one-line diagrams and project requirements, translating them into compliant, detailed electrical designs.
• Design low voltage switchgear assemblies in accordance with applicable regional standards
• Develop complete electrical schematic drawings using EPLAN or equivalent software, to the required accuracy and documentation standard.
• Prepare General Arrangement (GA) drawings in close coordination with the Mechanical Design team.
• Select and size electrical components — ACBs, MCCBs, contactors, relays, protection devices and busbar systems — appropriate to the project specification.
• Perform basic electrical calculations including fault level analysis, load calculations, cable sizing, busbar rating and thermal considerations.
• Ensure proper coordination and discrimination of protective devices across all designs.
• Incorporate control logic, interlocking schemes and communication interfaces (Modbus, Profinet, and equivalents) where project requirements demand.

Documentation & BOM Management

• Generate and maintain accurate Bills of Materials (BOMs) for all electrical designs.
• Support FAT procedures and prepare associated technical documentation to the required standard.
• Maintain structured, organized project documentation throughout the design and delivery lifecycle.
• Ensure all designs are compliant with IEC standards, client specifications and CEL's internal quality procedures, and that compliance is documented appropriately.

Cross-Functional Collaboration & Supplier Liaison

• Provide technical support to Production during panel assembly and wiring — resolving queries promptly and accurately.
• Liaise with suppliers for technical clarifications, component selection and confirmation of design feasibility.
• Collaborate actively with Mechanical Design, Project Management and Production to ensure designs are aligned with all functional, assembly, and project requirements.
