<br/><br/> Electrical wiring installation is vital in modern infrastructure, but the continued use  of conventional fish tape causes physical strain, inefficiency, and safety risks for  electricians. This study, “Design of an Automated Fish Tape (Wire Puller) Using DC  Motor Control for Electrical Wiring Installations”, aimed to design, fabricate, and evaluate  a cost-efficient and portable prototype suited for residential applications. A developmental  method was employed, integrating a 12V DC geared motor, rechargeable lithium-ion  battery, fiberglass-reinforced casing, and reel mechanism. Engineering analysis validated  conduit fill, pulling tension, torque, motor current, power demand, battery capacity, and  bending safety. Tests with certified NC II practitioners assessed portability, durability,  operational speed, and user experience. Results showed that the prototype reduced manual  effort and demonstrated durability and reliability, though its operational speed was rated  poor compared to the traditional fish tape. Despite this limitation, cost analysis confirmed  it as a practical and affordable alternative to bulky industrial models. The study concludes  that DC motor automation can modernize traditional tools and provide a safer, more  efficient option for electricians and technicians.
