Abstract
This study is analyzed for electrical fire danger by electric equipments through surveys of stable owners and the field investigation at 64 stable. Also, an experiment is performed to analyze the thermal characteristics of 4 types electric wiring according to the number of operating halogen warm lamp group and automatic waterer group in Beon-young stable in the Cheongwon location. The survey is done to investigate the occurrence of electrical fire, electric equipment, causes and dangerous equipment. As a result, halogen warm lamp group and automatic waterer group are found to have dangerous loads. In the field investigation, the mode of load capacity of the halogen warm lamp group and automatic waterer group was investigated. The mode of load capacity of halogen warm lamp group (over 3 years) is found 17A and that of the auto waterer group (10 years) is 16A. In this experiment, the halogen warm lamp group aged at least 3 years showed $109^{\circ}C$ while that aged less than 1 year appeared $83^{\circ}C$, showing the max gap of $26^{\circ}C$. The automatic waterer group aged 10 years showed $90^{\circ}C$ while that aged less than 1 year appeared $68^{\circ}C$, showing the max gap of $22^{\circ}C$. These findings indicate that the mode of load capacity needs to be considered in selecting and installing wiring for the electric equipment construction of halogen warm lamp group and automatic waterer group in stable.
