garage slab feeder dpth

[abe]

Hi
I am wondering about table 300.5
If a 2-00 amp feeder is in PVC SCH 40 and running under garage slab which is at least 4 inches of concrete, how deep the conduit should be? Table says no vehicular but garage slab is under one or 2 cars? If the conduit continues in a driveway which is used by 4 units and it has ASPHALT, then what is the required depth under asphalt? What if we pour 2 inches of concrete on the PVC conduit and fill with dirt and then asphalt? What depth is acceptable?

We bury the two feet. Most likely 30” but that’s because digging is easy here.

Ask your AHJ.

Inside the garage you are fine.

Table says no vehicular but garage slab is under one or 2 cars?

Table 300.5 does not apply to a garage.

When you are under a driveway Table 300.5 does apply, encapsulating it in concrete does not give any leeway to this.
