Final answer:
The minimum allowable depth that cathodic wiring can be buried without additional mechanical protection is typically around 2 feet or 0.6 meters. Burying the wiring at this depth helps protect it from potential damage and accidental contact.
Step-by-step explanation:
The minimum allowable depth that cathodic wiring can be buried in the ground without additional mechanical protection is typically around 2 feet or 0.6 meters. This depth is recommended to ensure that the wiring is adequately protected from potential damage, such as from digging or accidental surface disturbances.
By burying the wiring at this depth, it is less likely to be exposed to elements that could cause damage, such as surface water or sharp objects. Additionally, burying the wiring deeper also helps to prevent accidental contact by people or animals.
It's important to note that specific regulations and guidelines may vary depending on the country or region, so it's recommended to consult local building codes or electrical standards for the exact minimum allowable depth in a specific area.
