PARKING LOT PANELBOARD FEEDER DEMAND LOADING: A parking lot panelboard is supplying 62 parking stalls on 15 amp circuits which are
restricted or controlled. Determine the total calculated demand load in kW for the
FEEDER conductors supplying the panelboard.
The calculated demand load is kW

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
