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.

INTRODUCTION Electrical systems can not only be used to control all electrical systems in a building but can also be designed to receive information, display the data, and bring the information into the organization’s policy. Therefore, the design and development of electrical systems that are safe, reliable, stable, and efficient will build up confidence in the organization and create a competitive advantage in business. However, existing electrical control systems, or electri- cal switchboards, in buildings suffer from incompatibility of existing equipment and modern technology, leading to enor- mous losses of electrical power due to system management of tools. In addition, the existing systems still lack accuracy and reliability, and personnel are lacking in skills in the use of future automation systems. Environmental concerns and satisfaction of the users or customers with the systems and information to support decision-making in the future operations of the organization also need to be taken into consideration. 2. REVIEW OF RELATED LITERATURE A. Integration of the Internet of Things (IoT) to electrical control systems or electrical switchboards in buildings One way to solve the problem is an integration of the Internet of Things (IoT) to electrical control systems or electrical switchboards in buildings. In addition, the inte- gration can reduce the cost of producing superfluous power systems and reduce human errors which can also increase organizational reliability. The reliability of the organization is drawn from several elements such as the design of the electrical system, selection of electrical equipment, inspec- tion and maintenance [1].Improvement and optimization of electrical switchboard control equipment [2]can also build organizational credibility and acceptance. Currently electrical switchboard control devices are available in both low-voltage and high-voltage systems. Most of them are prefabricated and manufactured in Thailand for a variety of applications such as small industrial plants, large industrial factories, condominiums, buildings, hotels, shopping malls and medical facilities, etc. [3].For this reason, the devices may not be applicable for all types of organizations. B. Methods for optimizing electrical control systems Prior study (e.g., [4] [5] [6] [7] [8] )proposes a variety of methods for optimizing electrical control systems to meet the needs and scale of the organization to conserve energy and maintain the environment within the organization. For example, [4] has invented a more efficient way to inspect the electrical system, using a semi-automatic electric control system, which depends on the installation of electrical control equipment working with a person. Such an approach reduces the number of people and times to inspect the electrical system and the severe damage caused by a power failure. However, such an approach still requires an in- person and on-site inspection. Then, [5] have created a E-mail address: 62010990007@msu.ac.th, kittipol.w@acc.msu.ac.th https:// journal.uob.edu.bh
