I’d like to exchange about software for panel builders.
For design software in particular, I’d like to get some feedback about the interest (or not ?) of using electrical CAD software for electrical distribution switchboards (main switchboards and sub-switchboards), versus using a standard CAD software as I do today : Autocad or equivalent
you can find some articles already on the blog, see here
I just want to know what the busbar calculation faormula for MCC & PCC panel
i had to submit it to our consultant
How can define the curent carring capacity of copper /alumunum busbar?
Busbar calculation formulas or tables, which you can find here and there, are just very rough estimation methods to give you an idea of the copper cross-section required for the nominal current you need. But they give values which are very approximate, generally not optimized, for sure not guaranteed for the actual normal service & prospective fault conditions, and not taking into account short-circuit withstand level or the max acceptable temperature and quality of the busbar supports you are using …
I recommend that you refer to the international standard IEC61439-2 related to Power switchgear & controlgear assemblies, which defines how to design and verify LV assemblies in a safe way.
You may also suggest to your consultant, if he wants to get safe and reliable switchboards, first to ask for switchboards compliyng to this standard, second to ask and check certificates proving this compliance.
I will publish more detailed articles on this subject in the near future.
Your article is always rich but what i believe most people will love to know much about e;g the advance technology on the area of automation is the development into mechatronic world ( elect & mech ) please i as person will appreciate more info on this. Thanks
how do i get all the details about SCR, Resistor, Diode etc. used in electrical circiuts.
this subject is not really in the scope of my blog, but you can refer to some sites you’ll find with this google search
we require design software of Transfomer-Main ACB-Busbar- Outgoing cable Sub Distribution panel with ACB-TPN-Outgoing cable to load – load in KW .

Dan,
There are a number of ways to increase awareness of the site;
1) Exchange links with others in the industry
2) Social networks
3) Add more technical content. ie news on standards or review of specific area of a standard
4) Have you thought of providing online content for CPD (Continuos Professional Development) points
5) We are running a series of articles on emc on our site which is very popular
Good afternoon Mr’re a Brazilian demand to expand our products and come through this email, find out if you know the Liquid Silver and Rust Remover for copper bus used in control panels and power.

Liquid Silver
From a simple and efficient chemical process, with incomparably less than the cost system based on electrolytic bath, the Liquid Silver, provides a greater or lesser deposition of silver in the metal to be protected (copper, brass and bronze) in accordance with the number of times of application and exchange of contact material (steel wool) made by the operator.
The Liquid Silver can be used in any room of the factory.
• Rust Remover to Clean Copper
The Rust Remover is already prepared and ready for immediate use. It is generally used in manufacturing electronic, electromechanical, etc..
The Deoxidising brings in its composition, acting agents that promote rapid removal of layers of rust formed on copper parts.
