Abstract: The present invention provides a distribution panel having a smart vibration isolation device in which a ball is moved along a lower block while a vibration caused by a seismic wave is transmitted through upper and lower blocks each installed on the ground and the distribution panel with the ball interposed therebetween to minimize the vibration of the lower block from being transmitted to the distribution panel while the upper block supported by the ball supports the distribution panel, thereby implementing an effective vibration isolation function. A connection pad is installed on the outside of the upper and lower blocks to provide elastic support so that the upper block is prevented from being separated from the lower block caused by misalignment of the upper and lower blocks absorbing the seismic wave, thereby preventing accidents such as overturning of the distribution panel and the like due to the separation of the upper block in advance.
