For non-dwelling occupancies, banks, or office buildings, what is the minimum calculation for each receptacle outlet?

The correct minimum calculation for each receptacle outlet in non-dwelling occupancies, such as banks or office buildings, is established based on the National Electrical Code (NEC) and specific local regulations, which require a higher load capacity for commercial spaces compared to residential settings. This is due to the greater need for electrical devices and equipment typically found in these environments.

For office buildings and similar non-residential settings, the code recommends a load calculation of 180VA for each receptacle outlet. This figure accounts for the typical usage of electrical devices, including computers, printers, and other office equipment, ensuring that the electrical system is adequately sized to handle potential peak loads.

This standard is particularly significant because it accommodates the various appliances and tools that may draw power simultaneously, which is a common scenario in commercial spaces. Consequently, adhering to this requirement promotes safety and efficiency, reducing the risk of overloading circuits that could lead to outages or fire hazards.
