Issue:
Looking for the value of infrared emission of tin-plated copper bus for Type NF & NQ Panelboards.
Product Line:
NQ NF Panelboards
Environment:
Panelboards
Resolution:
Schneider Electric has not tested the emissivity of Square D NQ and NF Panelboard Bus Bars. However, the emissivity of electroplated copper is known.
The emissivity coefficient - ε - indicates the radiation of heat from a 'grey body' according to the Stefan-Boltzmann Law, compared with the radiation of heat from an ideal 'black body' with the emissivity coefficient ε = 1.
The emissivity coefficient, - ε -, of electroplated copper is 0.03
Note that the emissivity coefficients for some products vary with the temperature. As a guideline, the emissivities below are based on temperature 300 K (80.33 F).
