electrical-engineer-testimonyIsmail is a fellow electrical engineer from our community who got 5 years experience in designing electrical system for industrial, commercial, and residential.
Today he nicely accepted to tell us about his experience in industry, precisely the problems he faced and what he learned. Enjoy!

If you want to send us your stories too, just reach us by mail.

“It is always exciting for me to accept a job in designing electrical power system for industry. The problem, or I have to say the one which make me excited, is every company quite often has its own rule or even own standard! It becomes even worse if a company has a several factory and each factory adopt different standard (maybe because the factory has been built by different contractor).”

Ismael is specialized in designing electrical systems (LV and MV) for commercial, industrial, and residential. Let his 5 years of experience enlighten you and read now the answer to how to specify medium voltage switchgear for industrial plant!

IP codes

As Medium Voltage Switchgear often entirely enclosed within the building, it is paramount to specify the specification for its enclosure. IP code (Index of Protection or International Protection or Ingress Protection) state the environmental protection against the ingress of solid foreign objects and water.

megaphone1To begin year 2016, we’re glad to publish this article by a new member from Kenya, specialized in electrical installations, maintenance and repairs.

He told us about his experience (20 years!) and he kindly sent us this article about automatic transfer switches. We tought it was interesting and decided to post it on the blog.

Remember you too can send us material and be published in the Electical Engineering Community blog! Just send us a mail.

For now, let’s enjoy this article…

The automatic transfer switches are used to automatically transfer the load from the utility power to a secondary or backup power source whenever power goes out, or as required.

A careful selection of the switch ensures adequate capability, safety, and maximum reliability under both normal and emergency conditions. As such, one must consider technical factors such as the size, type of load, continuous current rating, voltage rating and style. In addition, the price, compatibility and reliability must be considered.

I am very upset!!

I am very upset!!

My name is Paolo, I am a Brazilian panel builder. I assemble low voltage power distribution panels using enclosure systems from International manufacturers also known as “functional” panels… and I’m tired of it! I can only state that the expectations are not met…

International manufacturers (ABB, Schneider, WEG…) promote “functional” or “modular” systems (for beginners sold in the form of kit, just like Ikea furniture!). The other solution is to use standard metal-sheet enclosures that many panel builders manufacture themselves.

I first thought that the kit system allowed me to save time with the assembling… However, there are a lot of drawbacks that make me question the relevance of this kind of “kit” offer…

Maintaining Low Voltage Switchboard (Tutorial)

Few weeks ago, we received this nice comprehensive guide in our boxmail. An electrical engineer sent it to us in order to help our junior maintenance technicians in the community who read the blog a lot!


Irrespective of the usage, electrical components tend to develop inconsistencies, just like any other components, as they age. Faults developed in electrical components, especially, in critical equipment such as switchboards and circuit breakers, are largely governed by the environmental conditions such as humidity, corrosiveness in the atmosphere, dust, dirt, etc.

Other factors that can affect switchboard efficiency are: operating loads, age of the equipment, current harmonics and poorly recorded maintenance reports.

In order to make sure that your low voltage switchboard operates properly and lasts long, it is imperative that you conduct preventive maintenance at regular intervals with the help of qualified professionals.

Following are some important guidelines to be followed while maintaining a low voltage switchboard:
