Which wires should be protected first when installing insulating blankets?

When installing insulating blankets, the priority for protecting wires is primarily focused on ensuring safety and accessibility. The correct choice emphasizes the importance of addressing the wires that are closest to the heat source and at the lowest elevation first. This is crucial because these wires are typically at the greatest risk of heat damage due to their proximity to hot surfaces or equipment.

In environments where heat is a concern, wires that are nearest to the heat will experience higher temperatures and potential thermal degradation more quickly than those that are farther away. Moreover, the lower elevation often makes them more vulnerable to environmental factors, such as moisture accumulation or accidental contact, which could lead to electrical hazards.

By prioritizing the nearest and lowest wires, installers can effectively protect the most at-risk components first, ensuring a safer working environment and preserving the integrity of the electrical system as a whole. This approach helps to mitigate risks associated with overheating and electrical failures, maximizing the effectiveness of the insulating blankets being applied.
