Final answer:
Laying cable six inches above fluorescent lights may cause electromagnetic interference, resulting in transmission issues, and the heat from the lights might damage the cable or create a fire hazard.
Step-by-step explanation:
The student's question pertains to the potential problems that may arise from laying cable in the ceiling tiles just six inches above a bank of fluorescent lights. One major concern is the potential for electromagnetic interference (EMI), which can result from the electrical magnetic fields generated by the fluorescent lights. If the cables laid above these lights are for data transmission, EMI can degrade the data signals, causing errors and reducing the overall data transmission quality. Additionally, there's a thermal issue to consider. The heat generated by the fluorescent lights may increase the temperature of the cable, leading to potential damage or reduced lifespan of the cable due to the heat exposure. Also, the cables might pose a safety risk if they heat up too much, potentially causing a fire hazard. It is important for these cables to be properly shielded and for appropriate clearances to be maintained in compliance with local building codes and standards for cabling and electrical installations.
