Management of electrical switchboards is conventionally performed by a person, and inspections may sometimes encounter problems with the switchboard when severe damage has occurred. To solve such problems, this investigation was to apply the Internet of Things (IoT) to increase communication channels through smart devices to control the operation of electrical switchboards via the Internet and applications to access data to monitor device operation remotely for more security, credibility, stability, and efficiency. These capacities will increase business competitive advantages in an application of electrical switchboard production. The findings indicated that users are satisfied with its efficiency in reducing errors and service time, and remotely fixing problems which are defects of the original system operation.
