Electrical Equipment Specification Sizing
Specify and size electrical equipment to meet system demands, safety requirements, and operational performance.
Service Overview
At Engineering Design Services, our electrical equipment specification & sizing services provide the detailed engineering needed to properly size, select, and define electrical equipment for industrial facilities. Our team evaluates system loads, fault currents, environmental conditions, and operational requirements to ensure each piece of equipment is correctly specified for its intended service.
Our team works closely with clients to translate electrical system studies and design requirements into clear, procurement-ready specifications for transformers, switchgear, MCCs, panelboards, generators, UPS systems, and other critical electrical assets. From early project development through detailed engineering and construction support, we ensure equipment selections align with both technical performance and real-world operating conditions.
By integrating power system analysis, vendor coordination, and industry standards, we deliver equipment specification packages that reduce procurement risk, improve reliability, and support long-term facility performance.
Whether supporting new facility builds, system expansions, or equipment replacements, our team delivers sizing and specification solutions built for accuracy, compliance, and operational success.
Engineering Challenge We Solve
Improperly sized or poorly specified electrical equipment can lead to system failures, safety risks, inefficiencies, and costly redesigns. Our approach addresses these challenges by:
Improving System Reliability: Ensuring equipment is properly rated for real operating conditions.
Reducing Procurement Risk: Preventing undersized or oversized equipment selections.
Enhancing Electrical Safety: Accounting for fault duty, arc flash exposure, and protection requirements.
Supporting Code Compliance: Aligning specifications with NEC, IEEE, NFPA, and manufacturer standards.
Optimizing Capital Costs: Balancing performance requirements with practical and cost-effective solutions.
Core Capabilities
Our team provides comprehensive equipment sizing and specification support across all project phases:
Transformer Sizing & Specification: Selection based on load demand, inrush, and system growth.
Switchgear & MCC Specification: Definition of low and medium voltage distribution equipment.
Panelboard & Load Center Sizing: Proper sizing for branch circuits and facility loads.
Generator & UPS Sizing: Backup and emergency power system analysis and specification.
Cable & Feeder Equipment Coordination: Ensuring upstream and downstream compatibility.
