Table 300.5 Column 3, Row 4

[tortuga]

Greetings all just want to confirm I am reading the code right
Table 300.5 Row 4

Under minimum of 102 mm
 (4 in.) thick concrete exterior
 slab with no vehicular traffic

Per note 1; Cover is defined as the shortest distance
measured between the top surface
of the PVC conduit and the top surface of concrete.
And we dont need the conduit to be 4 IN below the 4IN concrete slab (8 in below grade)?
Thanks in advance and stay safe.

I agree with your interpretation. You need 4" of cover which is provided by the 4" of concrete.
