Identification of Ungrounded Conductors. Today John Hauck and David Burtt discuss the identification of ungrounded conductors according to the 2011 National Electrical Code. This is part 1 of a 3 part series on identifying conductors.
The wet-bulb temperature is the temperature a parcel of air would have if it were cooled to saturation by the evaporation of water into it, with the latent heat being supplied by the parcel. A wet-bulb thermometer will indicate a temperature close to the true wet-bulb temperature. The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only. Wet-bulb temperature is largely determined by both actual air temperature and th
Tn is a ânaturalâ (static) wet-bulb temperature, observed by thermometer A, Tg is a âglobeâ temperature, observed by thermometer B, and T is the ambient air temperature, observed by dry-bulb thermometer C (Fig. 1).
