Calculate temperature of wire

WebFirst - how do we calculate the temperature: At the typical temperatures of a halogen bulb, the large majority of heat loss is due to thermal radiation (although there is some conductive loss in a halogen bulb as the bulb is not evacuated). Because of this, the most important factor is the "apparent size" of the filament. WebJul 21, 2024 · If the ambient is anything other than what the starting ampacity is in Table 310.16, then we will find temperature correction factors in 310.15 based on deviations from the original chart’s ambient temperature. There are two temperature correction tables: Table 310.15(B)(1) for tables that are based on an ambient temperature of 30 ⁰ C (86 ...
