ElectricalCalculating Electrical Loads for New Installation

The electrical system in your house must supply power to a large number of fixtures and appliances, from small devices like energy-efficient light bulbs to major machines like air conditioners and refrigerators. Every home will have different energy needs, and every home will have a different electrical system to meet those needs. When you have new electrical installation in Lynwood, WA, you must make sure that the two match. To do this, installers will calculate the electrical load necessary for the new installation.

Do not attempt electrical installation yourself, no matter how “simple” the task may seem. This is potentially dangerous work, and incorrect wiring can lead to overloaded power systems and electrical fire hazards. Only trust to the work of professionals, like those at G&S Heating, Cooling & Electrical, Inc., to manage new electrical installation.

The Electrical Load

The term electrical load refers to the largest power draw that the circuits in a system can handle. The amount of load depends on the level of resistance to current flow and the amount of voltage applied to it.

To determine the electrical load of a house when electricians are handling new installation, they must perform a residential load calculation. The installers will also make sure that the electrical load meets with the National Electric Code and/or local amendments and substitutions to it.

The basics of the calculation are to take the amperage of the new installation and multiply it by the voltage to get the resulting wattage. The installers then need to figure out the safe capacity for the circuit, using what is called “Ohm’s Law” (the current through a conductor between two points is directly proportional to the potential difference across the two points), and come up with a rating in wattage that the new installation cannot exceed.

This may sound a touch complicated—it’s electrical engineering—but keep in mind that this is why you want to hire experienced electricians to handle any new installation in your home. Whether you are having home renovations done, replacing old wiring, hooking up a new circuit breaker panel, or wiring a home theater system, have electricians present to assist from the start so that you know you will have the proper electrical load.
