Electrical Switchboard / control panel design
Basics on Switchboards & their General Arrangement drawings is a basic course to start learning about switchboard or their general arrangement drawings. We have covered various concepts that are required to design general arrangement drawings for low voltage switchboards. We start with very basics and eventually build on it.
This course is even suitable for students who want to learn about the switchboards or control panels.
Some of the topics that you will come across are:
