Free Electrical Load Calculation Spreadsheet

[Alexandrie Gallup]

Theresidential load calculation worksheet calculates the electrical demand load in accordance with Article 220 of the 2017 National Electrical Code. The worksheet helps to provide an accurate, consistent, and simplified method of determining the minimum size electrical service for a new or existing dwelling looking to add additional electrical load.

Electrical design without appropriate applications and tools is impossible to imagine. This section is dedicated to tools every electrical engineer can use in daily work. The software and spreadsheets below will make your job much easier, allowing you to shorten the time used for endless calculations of cables, voltage drop, various selections of circuit breakers, capacitors, cable size, and so on.

Hello,

I am from the Ecodial software partner team.

We integrate Ecodial into 3rd party software and applications.

Feel free to reach out and we can discuss how to integrate all the features of Ecodial inside your calculation software.

Chris

For load flow analysis, short circuit, Arc flash calculations, Harmonic load flow, Protection and automation,

Motor acceleration I advice you to try software EA-PSM. =PLtl3YJ4F1Jj4x-UDA4XF0tQmvgp5Rp_yX

wow, this web page is great , thank you a lot .

I am 25 , just finished my MS.c in power electrical system , and with a little experience

would you please give me some advise about electrical installation in ships ?

best regards from IRAN :)

I encourage you to give a try and share your opinion about new mobile apps for arc flash hazard analysis & labeling and short circuit fault current calculations. The apps are free and come with optional in-app purchase:

please find power system modelling and fault analysis software EA-PSM at -psm.

This software includes: power flow, short circuit, harmonic load flow, protection coordination, distance protection and coordination, motor start, export to dxf, word, excell.

Thank you very much for your most informative news.

My problem is, the home electrical bill/energy consumption/electrical load calculator did not work better for me.

Eg. I worked out the load current / power consumed by 10 x CFL bulbs 15W and got 470.68 A / 150kW (according to the calculator), and thus compelled me to install 600A Incoming ELCB in my residence?

Please take a look and advice.

First of all I must say thanks to EE Portal Team for dedicated services providing to engineering community and to all without difference and updating the Engineering Professionals with the latest information of Electrical Engineering . I shall suggest that some information may be given on Electrical Engineering Safety not general but specific in various opeartions of Electrical Engineering Systems, also Safety Softwares are required to be provided for free downloading. Hope the Portal will consider my suggestions. Thanks

I am an Electrical Senior Engineer with +9 years Experience who work in Schneider Electric Iran. I just express my appreciation for your well-organized web site which in most cases provide appropriate technical data. However in some case it could be improved with presenting more practical data, links, etc which are considered in daily routine design for electrical engineers. nevertheless I believe that good effort shall salute and you deserve that when spreading knowledge freely and helping Electrical Engineer community to boost their qualities. such web sites shall be supported and encouraged to follow their services.

I have been working as an electrical engineer at a manufacturing of m.v metal clad switchgear firm in Turkey.I have never seen any website like as your website.So ı would like say to developer of this website thank you very much indeed.I would like to share all information about middle voltage switchgears with everyone.

regards

I have the following questions, in the representation diagrams unifiliares has become almost customized, for example if you see the result of Autocad MEP is very rustic (but fulfills its purpose) They could advise me on where to get the updated symbolism and presentation flat.

Thank you for your kindness

Wow this web site is very much educative and full of aspiration in electrical world but I would want to please get the simulation softwares like matlab,control and Dot matrix.

thank you very much for your concern to young Engineers whom want to develop his career .

I look forward to talking with u soon .

thanks for your usual co-operation

hello,this teja and working as a design engineer in control panel mfrs and i would like to know how to calculate the busbar short circuit current calculation method by formula base ? and can give the control drawing for amf panel with two 500kva dg sets having auto sync and auto load sharing.

Thank You very much my friend, i lost my datas which is copied in my hard disk, but ur details which am downloading very useful to me recovery my engineering design skills. thanks lot, do the same think, God Bless YOU.

I recently qualified as an Electrical Engineer and found this site extremely useful in filling the gaps between theoretical knowledge obtained at University and the practical knowledge that is only gained through experience. Still have a lot to learn though but I will certainly visit this website often and I would certainly recommend it to others! *Thumbs up*

I'm in the process of trying to build a small hobby farm from scratch. One of the initial steps is to get temp service on the property, and to do so I have to fill out an electric load form. I will mostly be operating pumps, table saws, etc. Single phase, and most of the time not at the same time. Part of the sheet requires you to fill in the KVA and the KW of the different electric loads. I've done a fail amount of electrical work, but honestly these are metrics that I'm not familiar with. Can someone provide a little guidance on how one would fill this out? I vaguely recall from engineering school that the difference between KVA and KW is one is absolute and one is apparent power, but what that means within this context I'm not sure.

Curious,

Does anyone know if Chief Architect is equipped to be able to calculate electrical load? Or has someone built something within Chief that can do it?

Happy new year by the way! This is the first I have been able to sign on since my surgery!

Without having a complete list of all equipment (with loads) as well as the number and amperage of circuits this wouldn't be possible. It could be done - but only with customized electrical symbols, etc.

You could of course assign values to each item in Chief, but I'm not sure it would be faster. That being said, it could be worth doing if you're interested in creating your own library of electrical items and reuse them.

I have a spread sheet that I built and use to put in all the necessary information. I think you may be on to something by creating the electrical schedule and then transferring to a spread sheet. I will try that. Most of these detached ADU's are asking for it now so I thought maybe I could come up with something a little easier.

Thank You!

I've done one, uses custom fields and symbols. It also creates a panel schedule. I add a custom field for circuit, and that circuit can have an amp value which can report to a load macro. The a schedule that is split at side 1 and 2 and organized by macros called zone

the end results in a schecule that looks like a panel label and the load is stores in a global macro that can be put on a separate sheet.

Honestly I would have to rebuild it, I can't recall what plan I did it for and I did not save the system unfortunately. The load calc part is complicated, the panel label schedule is less complicated.

I can imagine... I don't have to do them often, but load calcs keep coming up. I've been just doing a basic schedule with simple spreadsheet for the circuits. Thought i'd poke around and see what you studs have been doing. Hope you are well buddy.
