We are running 3 wires and a ground in a RMC to a control panel with a 60 amp circuit breaker disconnect in the control panel. The conduit is run along the ceiling where the ambient air temperature is 100 degrees. The control panel feeds our secondary cooling pump. What size are the ungrounded conductors? All conductors have typeTHHN insulation. A #6 AWG B 600 Kcmil C #8 AWG D #2 AWG What size RMC do we need? A 3" B 3/4" C 1" D 1 1/2"

Refer to the National Electrical Code® or the working drawings when necessary. Where applicable, responses should be written in complete sentences. For problems 1 and 2, six luminaires, similar to Style E used in the Commercial Building, are to be installed in a room that is 12 ft x 18 ft (~3.7 m x ~5.5 m) with a 9 ft (2.8 m) floor-to-ceiling height. The spacing ratio for the luminaire is 1:0. 1. The maximum distance that the luminaires can be separated and achieve uniform illuminance is ft ( m). For problems 2-5, two luminaires, 8 ft (2.5 m) and 4 ft (1.2 m) in length with dimensions as shown in Figure 15-7, are to be installed in tandem (end to end). The end of the long luminaire is to be 2 ft (600 mm) from the wall. 2. The center of the outlet box should be roughed in at ft ( m) from the wall. 3.
