What is required above underground electrical installations buried less than 30 inches?

When it comes to underground electrical installations buried at a depth of less than 30 inches, a warning ribbon is required to alert individuals to the presence of the electrical installation below. This regulation aims to promote safety by minimizing the risk of accidental contact during excavation or landscaping activities. The presence of a warning ribbon helps ensure that anyone digging in the area is aware of the underground hazard and can proceed with caution.

The warning ribbon must be placed above the buried electrical lines and should be clearly marked with appropriate warnings, such as "Caution: Electric Line Below," making it easily visible and recognizable to workers or others who may be digging in that vicinity. This proactive approach helps prevent accidents and injuries related to unintentional strikes to the electrical installation.

In scenarios where installations are deeper than 30 inches, the risk is reduced, and different safety measures may apply, hence the requirement for a warning ribbon becomes particularly crucial for installations at shallower depths.
