For your continuance the Update and Calculate Buttons will Recalculate the entire form. Please use additional Question Mark Buttons for more specific information. This Residential Electrical Load Calculator is Pre-Loaded with electrical information for you to chose from. The question mark help buttons will assist you with detailed information about typical equipment loads which may be selected in the various drop down menus. The calculations conform to the national electrical codes which focus on required loads and factoring in the appliance and motor equipment. The load calculator is divided into three main sections which enable you to enter the necessary information about the home project and the proposed electrical equipment that will be installed. In some areas of the form below you can combine VA loads for multiple equipment with the specified section.Д«rief Instructions for the Electrical Load Calculator PF or Power Factor is the ratio of the actual power in watts to the apparent power in volt-amperes which is expressed as a percentage.Д®xample: 100% power factor is the best, however a typical power factor could range between 75 to 90%. The wattage is calculated by multiplying voltage times the power factor of the circuit.Д®xample: Watts = Voltage times the Amperage times the Power Factor. VA is a standard measurement of electrical power that is used for identifying electrical circuit component requirements.Д®xample: a 120 volt circuit which is providing 1 ampere = 120 volt-amperes.ДЄ watt is a measure of true power which is required to perform work at the rate of 1 joule per second. VA is the abbreviation for volt-ampere, which is a unit of power that is determined by multiplying the voltage and the amperage current in a circuit. The Basics of How Electrical Power is Measured and Calculated The Calculate Button Must Be Pressed when any changes are made to the form. Perform the Calculations: The Calculate button will perform calculations from the information you have provided in this form. Properly Identifying Heating and Air Conditioning Equipment is very important because the equipment typically requires a larger electrical load. Be sure to check the nameplate information for accurate calculations. Click on the Question Mark Buttons for more specific information relating to each section and entry.ДЄppliances and Motor Type Loads are typically larger equipment used in the kitchen, laundry room, garage. The Residential Electrical Load Calculator is Pre-Loaded with electrical information for you to chose from. The General Electrical Load Requirements are based on the inside square feet area of the home which is then used to calculate the basic lighting load and required appliance circuits. The national electrical codes are the basis of making sure the electrical service is sized properly and installed correctly. The purpose of the residential electrical load calculation is to accurately determine the size of the electrical service base upon the electrical equipment that will be installed.
