What is the maximum length for built-in dishwashers as specified?

1. 30 inches

2. 54 inches

3. 78 inches

4. 96 inches

The correct answer is: 78 inches

The specification regarding the maximum length for built-in dishwashers is rooted in code requirements that ensure proper installation and safety of appliances within residential settings. The correct length of 78 inches is derived from guidelines designed to accommodate space limitations and ensure that dishwashers can effectively fit into standard cabinetry without compromising their operational functionality. The 78-inch measurement includes considerations for adequate clearance and access to plumbing and electrical connections, which are critical for the dishwasher to operate correctly and efficiently. Additionally, this standard helps avoid issues such as improper installation that could lead to water leakage or electrical hazards. Understanding such specifications is important for inspectors to ensure compliance with building codes and safety regulations, ultimately leading to safer residential environments.
