FStep 4: Calculate consumed load. The consumed load is the quantity of electrical power that the load is expected. to consume. For each load, calculate the consumed active and reactive loading, derived as follows: Note The loads have been categorized into three columns depending on their. load duty continuous, intermittent or standby. Calculate the Total Service Load and Service Rating. Sup up the results from lines 7, 8, 9-16, and you will get the total service load in volt-amperes. Divide the result by 240 and write the total service load in the next line in amperes. Enter the electrical service rating and compare it with the service load.

Cooling and Heating Load Calculation Principles, by Curtis Pedersen, Daniel Fisher, Richard Liesen, and myself. The Load Calculation Applications Manual, also sponsored by TC 4.1, builds on the past three, and some parts are taken directly from previous versions. New develop-ments in data and methods have led to numerous revisions. Jun 24, 2003 Art. 220 - 2 TOTAL LOAD DIVIDED BY: volts = Amps [ NOTE: For 120/240 Volt systems use 240 volts; for 120/208 Volt systems use 208 volts ] Art. 220 - 10 MINIMUM SERVICE SIZE AMPS Table 310 - 16 SERVICE ENTRANCE CONDUCTORS AWG, Cu, AWG, Al. Table 250 - 94 GROUNDING ELECTRODE CONDUCTOR AWG Copper OPTIONAL CALCULATION FOR DWELLING UNIT. Load calculations in the National Electrical Code have evolved over many decades. It was in the 1933 NEC that load calculation requirements began to resemble a format that the modern code user would find familiar. Since then, many things have changed, but the primary requirement remains the same service equipment and conductors must be sized to handle the expected load.

Example - You have a motor with a FLC of 10 amps and a heat load of 15 amps on a feeder. Largest motor = 10 amps x 125 = 12.5 amps plus the additional heat load of 15 amps = 27.5 amps Even though the heat load FLC was greater than that of the motor, we still added the 25 to the largest motor!. Above cooling load calculation. Calculating EER, the ratio of the heat thermal energy removal to the electrical energy required to move it by the compressor, condenser and evaporator fans. Using our system calculations above: 1 refrigeration ton = 12,000BTU = 3.5KW P = Electrical power rating of the A/C system = 2KW.
