# Demo of online electrical load calculator Online Electrical Load Calculator is a useful tool for construction professional to make perfect calculations for residential electrical panel load.

Given below, the detailed guidelines for the Electrical Load Calculator.

The objective of the residential electrical load calculation is to define the size of the electrical service precisely on the basis of the electrical equipment to be installed. To ensure the proper size and perfect set up of the electrical service, the national electrical codes are abided by.

Step 1: The General Electrical Load Requirements are subjected to the inside square feet area of the home that is required to work out the basic lighting load as well as necessary appliance circuits. The electrical information is pre-loaded with residential Electrical Load Calculator for the users to select from.

Step 2: Appliances and Motor Type Loads normally stand for bigger equipment that is mostly found in the kitchen, laundry room, garage. Ensure to verify the nameplate information for making perfect calculations.

Step 3: Extensive electrical load is essential to set up heating and air conditioning equipment. So, exact knowledge is necessary for recognizing Heating and Air Conditioning Equipment.

Step 4: The calculations are done through the Calculate button based on the information submitted in this form. If any modifications are done to the form, the calculate button should have been pressed.

The basics of how electrical power is measured and calculated.

Definition of VA: VA stands for the short form of volt-ampere, that is a unit of power obtained by multiplying the voltage and the amperage current in a circuit. VA belongs to a standard measurement of electrical power useful for recognizing electrical circuit component requirements.

As for instance: a 120 volt circuit offering 1 ampere = 120 volt-amperes.

The variation among VA and Watts: A watt is a unit of measurement of true power that is essential to accomplish work at the rate of 1 joule per second. The wattage is calculated by multiplying voltage times with the power factor of the circuit.

As for instance: Watts = Voltage times x the Amperage times x the Power Factor.

Definition of Power Factor?
PF or Power Factor refers to the proportion of the actual power in watts to the visible power in volt-amperes that is stated as a percentage.

As for instance: 100% power factor is desired, however a standard power factor varies among 75 to 90%.
