What is the standard practice for height placement of receptacles in residential installations?

1. 12 inches

2. 16 inches

3. 24 inches

4. 30 inches

The correct answer is: 16 inches

The standard practice for height placement of receptacles in residential installations is typically 16 inches above the finished floor. This measurement aligns with the common practice to ensure accessibility and usability for standard household needs. This height is convenient for plugging in devices without having to bend excessively, striking a balance between accessibility and aesthetics. Furthermore, the 16-inch height is often used to accommodate various furniture styles and designs, ensuring that the receptacles are not obstructed by furniture and remain easily reachable for homeowners. This height is consistent with building code requirements in many jurisdictions, promoting a uniform standard across residential installations. In contrast, the other listed heights, such as 12 inches, 24 inches, and 30 inches, may not provide the same level of convenience or may not adhere to the standard practices typically employed in residences. Each of these heights could potentially lead to less effective use of receptacles for general household activities and devices.
