That "something" that is "telling you", might be 6-208. Underground is OK but 50 ft through the parkade is not allowed.

Where judgement required about "as close as practicable", the following may be used for
guidance on the maximum length of run:

(i) 1.5 m into rooms or areas of combustible construction; or

(ii) 7.5 m into other areas provided:
„h the wiring method is rigid conduit, electrical metallic tubing (EMT) or a cable
with a continuous metal sheath or interlocking armour, (No PVC greater than
625mm2 as per Building Code), and
„h the conduit or cable is mechanically protected where it is within 2 m of the floor.
