what is the maximum cover requirement in inches for direct burial UF cable installed outdoors that supplies power to a 120V, 30A circuit?
a. 6in b. 12in c. 18in d. 24in
Refer to “Table 300.5 Minimum Cover Requirements, 0 to 100 Volts, Nominal, Burial in Millimeters (Inches)” of National Electrical Code (NEC).
From column-1 of the Table 300.5, the minimum cover requirement for direct burial UF cable installed outdoors that supplies power to 120 V, 30 A circuit is 18 Inches.
As the UF labelled underground feeder cables have a tough jacket designed for burial, they can be buried without an additional protection from conduits. The UF labelled ...
