What is the maximum cord length for a 100-volt window A/C unit?

5 feet
7 feet
10 feet
15 feet

The correct answer is: 10 feet

For a 100-volt window air conditioning unit, the maximum cord length specified is 10 feet. This limit is in place primarily for safety and efficiency reasons. Longer cord lengths can increase the risk of overheating due to the additional electrical resistance introduced over longer distances, potentially leading to fire hazards. A shorter cord length also ensures that the air conditioning unit operates effectively and receives adequate voltage without significant loss during transmission. While shorter lengths might be allowable in other contexts, air conditioning units, given their power demand and the necessity for reliable operation, have specific guidelines. The considerations for load capacity, safety standards, and efficiency are essential when determining the appropriate cord length for such devices.
