As the social interest in seismic design of telecommunication facilities increased in the early 2000s, studies on the development of seismic electrical cabinet in ordinary buildings began to be conducted. In Korea, various methods have been suggested to improve the seismic performance of electrical cabinet for ordinary building, but only a few of them are actually used. In this study, seismic isolation device was developed, based on the results of the nonlinear time history analysis, to increase the seismic performance of the electrical cabinet, and the seismic performance was verified by shaking table tests. The results of the analysis and tests are as follows; (1) Proposed simplified model showed the possibility of being usefully used to grasp the dynamic characteristics of the electrical cabinet. (2) As a result of shaking table tests, the maximum bottom shear force was reduced by 55% and operated normally to satisfy the demanded performance of the electrical cabinet. (3) A series of processes performed in this study, seismic isolator can be useful in the development of seismic isolators for electrical cabinet in the future.
