Demand load

• In general, the total power required by a facility. The demand load is the sum of the operational load and nonoperational demand loads. It is determined by applying the proper demand factor to each of the connected loads and a diversity factor to the sum total.
• At a communications center, the power required by all automatic switching, synchronous, and terminal equipment, control and keying equipment, plus lighting, ventilation, and air- conditioning equipment required to maintain full continuity of communications.
• The power required for ventilating equipment, shop lighting, and other support items that may be operated simultaneously with the technical load.
• The sum of the technical demand and nontechnical demand loads of an operating facility.
