Hello, I am Muhammad Javed, an electrical engineer with more than 10 years of experience in industrial electrical systems, power distribution, cable sizing, voltage-drop calculations, and electrical design in accordance with applicable standards. I can accurately calculate and select the consumer’s mains required for the proposed 800A industrial supply, considering the less-than-50 m cable run between the supply point and main switchboard. I will assess the appropriate conductor size, number of parallel runs if required, installation/derating conditions, voltage drop, current-carrying capacity, short-circuit considerations, and relevant protection requirements. Since future load expansion is not required, I will base the design on the specified 800A demand and the actual installation conditions rather than unnecessarily oversizing the system. I will provide clear calculation results and design assumptions so the selected mains arrangement can be reviewed and used confidently for the project. I am experienced with industrial power distribution and high-current electrical calculations and can deliver accurate, practical, standards-based engineering work. I can start immediately once the installation details and applicable local standard are confirmed

⭐⭐⭐⭐⭐ I can carry out the 800 A industrial mains sizing calculation and provide a documented, standards-based design recommendation for the sub-50 m run to the main switchboard. I’ll assess more than conductor ampacity alone, including: • Supply voltage, phase arrangement and prospective fault current • Cable/conductor material, installation method and grouping • Continuous-load and temperature derating factors • Voltage drop over the <50 m run • Short-circuit thermal withstand • Main protection and cable coordination • Termination/busbar ratings and practical installation requirements • Applicable electrical standards, utility requirements and local regulations I’ll provide the calculation methodology, assumptions, selected conductor arrangement/size, voltage-drop results and protection considerations so the result can be independently reviewed by your electrician or electrical authority. Before finalizing the sizing, I’d need the jurisdiction/code basis, supply voltage (e.g. 400/230 V or 480/277 V), 1/3-phase arrangement, conductor material, and proposed installation method. These can materially change the required cable arrangement. I’ll keep the calculation focused on the specified 800 A present load and will not add unnecessary allowance for future expansion, as requested.

I can prepare the mains cable sizing calculation for the 800A industrial supply, including current-carrying capacity, applicable derating factors, voltage drop, and conductor configuration based on the installation conditions and applicable electrical standard. Before starting the calculation, I’ll need the supply voltage and phase configuration, conductor preference (Cu/Al), cable length, installation method, ambient conditions, cable grouping if applicable, upstream protection details, available fault level or short-circuit current if known, and the required design standard. I’ll use these inputs to determine the required conductor size and number of parallel runs, then check the proposed arrangement against the relevant capacity and voltage-drop requirements. I can provide the calculation clearly documented so the assumptions, inputs, formulas, and final recommendation are easy to review. If some site or fault-level information is currently unavailable, I can identify exactly what is missing before finalising the sizing rather than making unsupported assumptions.

@onlin666

I'm an electromechanical engineer and have worked at a design institute for many years. If you're dealing with 800A of high current, I wouldn't recommend using cables since the distance is relatively short. Busways would be a better choice.

@eshmumkhan

Hello. My name is Eshmum, and I am a licensed electrical engineer with over 10 years of experience designing industrial power systems, and I have successfully completed similar projects including consumer mains sizing for a 630A supply at a manufacturing plant and cable selection for a 1000A industrial distribution board. I understand you need a professional calculation to determine the correct consumer mains size for an 800A supply to an industrial building with a cable run of less than 50 metres and no future load expansion required. My approach will perform the mains size calculation in full compliance with AS/NZS 3000 and AS/NZS 3008.1.1, considering current-carrying capacity, voltage drop below 2%, and short-circuit protection. My deliverables will include a detailed calculation report in PDF format with cable size recommendation and code references.. I am ready to start immediately. I look forward to collaborating. Best Regards. Eshmum.

@amiran42

A wrong consumer mains size for an 800A industrial supply can mean overheating, voltage drop issues, and compliance problems—especially with runs under 50 m feeding the main switchboard. I’ll size the conductors and assess protective device coordination so the design stays within safe thermal limits and acceptable voltage regulation. Using the available installation data (cable type, ambient/installation method, insulation, grouping, switching/starting considerations if any), I’ll perform the full current-carrying capacity and voltage drop calculations, then verify with applicable standards/regulations and practical derating factors. No future load expansion will be assumed, matching your scope. Share your supply details (phase, voltage, TM/CT ratio if relevant, installation conditions, and switchboard arrangement) and I’ll return a clear calculation report with recommended mains size, cable spec basis, and next-step wiring implications—ready for your engineer review.
