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
The upper display can indicate the calculated RH, peak RH (maximum) or valley RH (minimum). The middle can indicate dry bulb temperature or setpoint, while the lower can indicate wet bulb temperature, dew point temperature or the difference between dry and wet bulb temperatures.
