@azraazeen9

As an Electrical Engineer with a specialization in industrial design, I am well-versed in the intricate complexities of generating Load Calculations and Single Line Diagrams (SLD) for industrial facilities. My deep familiarity with the relevant codes like NEC, coupled with my command over AutoCAD, make me capable of producing professional-grade PDF outputs with editable source files in AutoCAD - just what you are looking for. Throughout my career, I have frequently engaged in projects of similar nature, involving extensive load calculation and diagramming work for manufacturing units, power plants, and warehouses. One such recent project involved designing electrical circuitry for a large-scale food processing facility operating on 30 kV voltage class. My understanding and application of demand factors meticulously catered to their specific requirements. In another instance, I designed an SLD for a heavy machinery factory emphasizing trouble-free fault levels and pragmatic equipment hierarchy that optimized their operational efficiency. My solid workflow and keen attention to detail ensured a smooth review process within strict deadlines.

As a highly experienced electrical engineer, I'm confident that my skills and background align perfectly with your project requirements. Over the years, I have consistently demonstrated my ability to handle industrial automation projects, including wastewater treatment plant automation and water treatment plant automation. These projects required an astute knowledge of electrical calculation, familiarization with operative NEC tables, and drafting schematics using AutoCAD, which I accomplished successfully. One of my notable examples is working on a HES project where I designed the PLC and SCADA system for generators. In this capacity, I learned to skillfully perform load calculations based on varied voltage classes while still adhering to regulatory requirements. Additionally, constructing single-line diagrams holding crucial information about breakers, feeders, grounding and fault levels was a key component of my duties as these helped ensure the entire system ran efficiently.

Hi, I can prepare the industrial facility electrical load calculation and single-line diagram with clear feeder sizing, panel schedules, protective-device references, grounding, and editable source files. My approach will be to first review your architectural layout, equipment list, utility/service data, voltage level, panel locations, and applicable standard. Then I’ll prepare the load calculation sheet first, apply demand factors, size feeders/breakers/conductors, and use that basis to create a clean annotated SLD. I’m comfortable with industrial electrical load calculations, NEC-style sizing references, panel schedules, feeder and breaker sizing, grounding notes, fault-level notation, AutoCAD SLD drafting, Excel calculation sheets, and technical documentation. Deliverables: * Electrical load calculation * Demand factor application * Panel schedules * Feeder/conductor sizing notes * Protective device sizing * Single-line diagram * Utility-to-panel hierarchy * Breakers, feeders and grounding shown * PDF outputs * Editable Excel calculation file * Editable AutoCAD/source file I’ll provide the load calculation draft first for review, then complete the SLD after feeder sizes are confirmed. Note: PE stamp/local authority approval is separate if required. Best regards Ankit

Hi ? I can prepare a complete industrial electrical load calculation and code-compliant single-line diagram based on your architectural plans, equipment schedule, and utility data, with careful application of NEC demand factors, conductor sizing, protective devices, grounding, and fault-level requirements. I’m comfortable working with industrial distribution systems, panel schedules, feeder coordination, service calculations, and clear equipment hierarchy from utility service through downstream panels and major loads. I’ll develop the load calculation first to establish defensible feeder and breaker sizes, then reflect those values consistently in the annotated SLD so the two documents remain fully coordinated. The deliverables can be organized as professional PDF outputs with editable Excel calculation sheets and AutoCAD-based source drawings for future revisions. I’ll also review the package for calculation consistency, labeling, grounding paths, breaker ratings, and code references before handoff. I’d be pleased to discuss the facility data and help turn it into a clear, engineering-grade electrical package.
