Instruction in electrical installation requires media capable of presenting concepts in a concrete and interactive manner. Limitations in visualization media can hinder students' understanding of the abstract and technical concepts involved in electrical installations. This study aimed to develop and assess the feasibility of an Augmented Reality (AR)-based electrical installation learning module as an innovative instructional tool. The study employed the Research and Development (R&D) method using the 4D development model (define, design, develop, and disseminate). Validation was conducted by two subject matter experts and two media experts. A validation sheet utilizing a Likert scale served as the research instrument, and data were analyzed using descriptive quantitative methods based on feasibility percentages. The results indicated that the module achieved a feasibility score of 80% from subject matter experts (classified as "feasible") and 82% from media experts (classified as "highly feasible"). Based on these validation results, the AR-based electrical installation learning module is deemed suitable for use as an instructional medium. The use of AR offers the potential to provide a more contextual and engaging learning experience while helping students grasp electrical installation concepts more effectively
