What is the total power requirement for the dryer in the multi-family building?

To determine the total power requirement for a dryer in a multi-family building, several factors must be taken into account, including the dryer’s rated wattage and the electrical specifications per the National Electrical Code (NEC) or local building codes.

A typical residential electric dryer generally has a power rating between 4,000 watts (4 kW) and 5,500 watts (5.5 kW). In larger multi-family applications, dryers may be slightly larger in capacity or power to account for increased demand. Hence, a power requirement of 4.50 kW is representative of an average electric dryer, taking into account operational efficiency and load calculations often utilized in multi-family settings.

When assessing the total power load, it is essential to consider that dryers typically operate on a 240-volt circuit, using a combination of both voltage and current to reach the given power value, expressed in kilowatts (kW). The choice of 4.50 kW reflects a reasonable estimate for a single dryer unit in a shared environment, ensuring sufficient capacity without unnecessarily high energy consumption.

Understanding the context and the average specifications of dryers helps clarify why 4.50 kW is the correct choice among the provided power levels, aligning closely with
