ELV (Extra-Low Voltage) Design in a building refers to the planning, integration, and implementation of various low voltage systems. This plays a crucial role in modern building infrastructures. Unlike power distribution systems that operate at higher voltages, ELV systems run on significantly lower voltages. This is usually 50 volts or less. These systems encompass a wide range of technologies. That includes communication, data, security, automation, and audio-visual systems. These systems work in conjunction to enhance the overall functionality, safety, and
