Electrical control panel design, Installation and maintenance


Electrical Control panel is an integral part of Electrical and Automatic control system used in the industries to control production process or machines. It may be built around Components such as Relay, Contactor, timer, counter, breaker or around programmable devices such as PLC, PAC, VFD, IED, etc. this is a very specialized field with a very few skilled personnel albeit very high industrial demand.

Who need this training
this training is meant for Engineers and technicians of Electrical/Electronic and computer background also, scientists with good electrical/electronic background. Both fresh graduate or experienced professional who may like to gain more skills

Course Objective
At the end of this Training our trainees will be able to:
