Basics on Switchboards their General Arrangement drawings


Should have a basic knowledge or degree in Electrical Engineering – B tech, B.E., Diploma or any similar relevant educational background


Electrical Control panel – Basics & considerations for general arrangement (GA) drawings for Switchboard / control panel /Electrical PanelsElectrical Switchboard / control panel designBasics 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 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: 1) Basic details on Switchboards & GA Drawings What is GA drawing? Where is it used ?Why is it needed? What are the inputs required to draw a GA drawing? Variations in GA drawings Basic Building blocks of a Switchboard or GA drawings. 2) Feeders / Modules/ Functional Units Basics on feeders / modules /functional units. Different feeder types : Incomer / Bus-coupler / Outgoings / Motor Feeders etc. Basic considerations for feeder sizing / module sizing Basic considerations for feeder placement 3) Switchgear – ·ACB’s, MCCB’s, Other plate mounted components, door mounted components, Heat generating equipments etc. How they affect the feeder sizing and, in turn, affect the placement in Switchboards Consideration for din-rail mounted components Consideration for mounting and placement of CT’s & PT’s Heat generating equipments How interlocks affect feeder placement4) IP Protection What is IP protection?Why is it important?How is it important for Electrical Switchboards?What is the significance of the 2 digits in IP rating?IP’s Applicable for Electrical Switchboards – Motor Control Centers and Power control centersWhat various IP’s mean: IP 42, IP 54, IP 55 etc.How IP protection impacts ventilation arrangement  5) Form of Segregation What form of segregation is?Why segregation is required ?What are the various forms of segregation?6) Different variations of panel design and how they define the GA drawing Single unit panelsMulti unit panelsOn what basis is a particular design of panel selected?Full height feeders7)  Vertical dropper rating and sizing & diversity factor. And lastly Practice ExerciseHow vertical dropper rating is decided.What is diversity factorSUP’s & MUP’s – Various possibilitiesWhy a certain design is selectedTotal vertical count Optimum feeder placement
