Where would you find the information needed to determine the amount of wire for installing a duplex?

To determine the amount of wire needed for installing a duplex, the electrical layout is the most pertinent source of information. The electrical layout provides detailed diagrams and specifications on the placement of electrical outlets, switches, fixtures, and other components. This layout helps in assessing the total distance between these elements, which directly informs the quantity of wire required for the installation.

The electrical layout may also indicate the type of wire needed based on the expected load and circuit requirements, ensuring compliance with electrical codes and standards. This information is essential for planning and executing an efficient and safe wiring installation.

While blueprints and project specification sheets contain valuable information, they may not offer the specific details on wire requirements and distances between electrical components that the electrical layout does. The materials list, on the other hand, may list wire quantities needed but would typically be generated from the measurements taken from the electrical layout itself.
