The bright lights and exciting sounds of arcade machines are a staple of entertainment venues worldwide. However, behind the fun lies a complex electrical system that must adhere to rigorous safety standards to protect both players and operators. These standards are designed to prevent electrical shock, fire hazards, and other potential dangers. This article outlines the key electrical safety standards and components critical for arcade machine compliance.

A primary standard for arcade machines, particularly in North America, is UL 60950-1 (Information Technology Equipment Safety) or the newer UL 62368-1 (Audio/Video, Information and Communication Technology Equipment). These standards, set by Underwriters Laboratories (UL), cover essential safety aspects such as insulation, grounding, and the spacing between electrical components to prevent short circuits. In the European Union, the CE mark is mandatory, indicating conformity with health, safety, and environmental protection standards, which often involves meeting the Low Voltage Directive (LVD) 2014/35/EU. The international equivalent is often the IEC 60950-1 or IEC 62368-1 standards from the International Electrotechnical Commission.

Several key components within an arcade cabinet are subject to these stringent requirements. The Power Supply Unit (PSU) must be certified (e.g., UL or CE listed) to ensure it properly converts wall power to safe voltages for the internal boards and monitors. It must have adequate overload and short-circuit protection. All internal wiring must use the correct gauge for its current load and feature sufficient insulation. High-voltage areas, like those near the CRT monitor or power supply, require physical guarding or insulation to prevent accidental contact. Furthermore, every fuse must be of the correct type and rating to interrupt power in case of a fault, and accessible components like coin doors and control panels must be grounded to prevent static discharge or shock.

Beyond the core electrical systems, other safety considerations include the use of certified power cords and the proper labeling of all components. Regular maintenance is not just a recommendation but a necessity for ongoing safety. Operators should routinely inspect for damaged wires, loose connections, and the integrity of insulation. Ultimately, adhering to these electrical safety standards is not merely about legal compliance; it is a fundamental responsibility to ensure a safe and enjoyable experience for everyone.
