By looking into the figure above, the Total Connected Load and the Maximum Demand is 2.57kW and 1.36kW respectively.
How The Calculation Works?1. The unit for TCL and MD is in Watt. Therefore, all the loads need to convert into Watt.a) 2hp a/cond split unit = 2 X 746W = 1492Wb) 2X36W Flou. Fitting = (2 X 36W) + Ballast Wattage = 80Wc) 13A Socket Outlet = 250W (this is rather subjective since some engineer putting 300W/nos)2. Determine the Diversity Factor (DF) for the respective load. The DF is the percentage of load that will contribute for the total of the Maximum Demand. For the above example, I’m expecting the split unit will contribute 6o% of the total MD, lighting will be 80% and socket outlet is 40%.3. Multiply the Diversity Factor with the Connected Load to get the Maximum Demand.4. Summing-up the individual MD to obtain the Total MD.Why I Need To Calculate The TCL and MD?By calculating the TCL, you’ll know the total load connected for a particular area and also you can determine the sizing of cables. But, the most important thing is by having the TCL, you can determine your MD. This MD will be declared to the utility provider for the purpose of meter deposit and utility bill.
Connected load:
It is defined as the sum of ratings of all electrical equipments that are connected at the supply point regardless of their status of operation It is calculated depending on the installed equipment without measuring or testing their actual demand The connected load, which is independent of time, is greater than the maximum load demand.
Demand load:
It is not obligatory that the maximum demand is equal to the connected load It is calculated in a certain time interval by measuring the greatest load demand during this time interval
Connected load. : the total electric power-consuming rating of all devices (as lamps or motors) connected to a distribution system.
The demand load is the sum of the operational load (including any tactical 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.
Total Connected Load (TCL) is the mechanical and electrical load (in kW) that will be connected (or to consumed) for that area. The Maximum Demand (MD) is the total kW that contributes the total power used in one time after applying the diversity factor based on the Total Connected Load.
Connected Load is the total load you have connected to a supply panel.
The maximum demand load is the maximum load that is on during a predetermined period of time. eg Diversity.
The connected load is the system of load actually connected while demand load is the portion of connected load than is nominated for a power plant to supply.
connected load is the total load connected to the grid where as demand load is the load in service, i.e. load excluding the idle load or load not in use.
Connected Load is the total load you have connected to the 400 amp panel. The demand load is the maximum load that is on during a predetermined period of time.
the total electric power-consuming rating of all devices (as lamps or motors) connected to a distribution system
The demand load is the sum of the operational load
Demand load permits demand-factor reductions, and excludes the lesser of items when only one can be on at a time, such as heating and cooling. Connected load is exactly what it implies.
Connected Load is the total load you have connected to the panel. As you probably know, all of that load is not on at the same time. The max demand load is the maximum load that is on during a predetermined period of time. If you live in a hot summer time region, the the peak load may be from 9am to 8pm when the A/C is running all of the time
