Abstract:
The purposes of this experimental research were to study the heat build-up in power strips, to experiment with thermochromic sticker discoloration, and to study the effect of discoloration of thermochromic stickers in power strips. The sample group comprised standard and non-standard power strips 3 brands each type. Data were collected through 3 experiments. Data were analyzed by using descriptive and inferential statistics, including paired sample t-test independent and One-way ANOVA. The results revealed at 100 percent of the electric current capacity of the power strip. Heat build-up average was the highest for brand E at 38.60 (SD±0.10) degrees Celsius. The results of experiment for thermochromic sticker discoloration using the heater temperature was the average was 31.54 (SD± 0.2). The results of the effect of discoloration for thermochromic stickers by comparing the average temperature and time revealed that all brands decreased significantly (p-value<0.05) except brand B and brand E, which showed the temperature average had no statistically significant difference. The study experiment in laboratory at room temperature with limited ambient temperature control. Ambient temperature should be considered in order to obtain the heat buildup in power strips that cover and apply to other electrical appliances such as fan motors, etc.
