These are loads that require a short, but intense surge of electrical energy, such as power tools, electric drills, and vacuum cleaners. Lighting loads can vary significantly depending on the type of lighting used, the number of fixtures, and the hours of use. These are loads that are associated with lighting fixtures, such as incandescent bulbs, fluorescent lamps, and LED lights. They require a surge of electrical energy when they are turned on, and then settle into a lower level of energy usage. These loads run for short periods of time, such as washing machines, dishwashers, and microwave ovens. They require a steady and continuous supply of power. Continuous loads:Ĭontinuous loads run non stop, such as refrigerators, air conditioners, and dehumidifiers. These are loads that need to be considered when estimating your electrical needs of building.

In order to calculate the electrical load for your home or building, it is important to get familiar with some basic types of electrical loads.

Transformer loads: Loads from devices that change the voltage level of an electrical circuit, such as transformers.īasic types of electrical load in buildings.

Capacitive loads: These are loads from devices that store electrical energy, such as capacitors used in motor starters, buried cables and capacitor banks.

Inductive loads: The loads from devices that use electromagnetic fields, such as motors and transformers.

Resistive loads: These are loads from devices that convert electrical energy into heat, such as electric space heaters and toasters.

The size of your electrical service panel is based on this calculation.Įlectrical loads can be classified into different categories, such as:

It is measured in units of power, such as watts (W) or kilowatts (kW). An electrical load refers to the amount of electrical power that is being used by a device, system or facility at a specific point in time. What is an electrical load?īefore we start, let’s understand what an electrical load is. In this blog post, we’ll go over the steps for how to calculate electrical load estimate for your building. This ensures that the electrical system is properly designed and sized to meet the needs of the occupants. Are you planning to calculate electrical load estimate for a new home or office space? It is an important step in the construction process for the building.
