According to article 300.5, isolated phase installations are allowed in accordance with exception 2,to sec.300-5 (i). While this exception allows installations in nonmetallic raceways, or cables with a nonmetallic covering or nonmagnetic sheath... why does it not state nonmagnetic conduit instead of nonmetallic? See Article 300.20(B)FPN. Also does't article 300.5 apply only to underground installations?
