Final Answer:
The statement 'The installation of FIGURE 4 'complies with' the box fill requirements of the CEC. The octagon is 4 x 2 1/8 inches in dimension and all the wires are #14 AWG copper.' is false because The installation of FIGURE 4 'does not comply with' the box fill requirements of the CEC. Rule 12-3036 in the Canadian Electrical Code (CEC) specifies the maximum number of conductors allowed in a box based on their sizes, and the given dimensions of the octagon and the wires exceed the permitted fill requirements for a standard electrical box.
Step-by-step explanation:
According to Rule 12-3036 in the Canadian Electrical Code (CEC), the box fill requirements dictate the maximum number of conductors allowed in an electrical box based on their sizes and configurations. The installation described in FIGURE 4 features an octagon measuring 4 x 2 1/8 inches and utilizes #14 AWG copper wires. To determine compliance with box fill requirements, one must refer to the code's specifications.
Calculating the box fill involves using specific formulas outlined in the CEC. The dimensions of the octagon box and the size of the #14 AWG copper wires will contribute to the overall fill calculation. Considering the dimensions provided, along with the gauge of the wires, the space available within the octagon box might not be sufficient to accommodate all the conductors while meeting the CEC's prescribed box fill limits.
As per Rule 12-3036 in the Canadian Electrical Code, the fill capacity of electrical boxes ensures safety and prevents overcrowding of conductors, which could lead to overheating or potential hazards. Therefore, based on the dimensions of the octagon box and the #14 AWG copper wires described in the installation, it appears that the arrangement exceeds the maximum allowed fill requirements outlined in the CEC.
