As long as the transformer has the required protection noted in Art 450.3
you can make your statement and exclude the word "outdoors" if you obey the corresponding tap rules.
In other words, a properly protected (primary) transformer can feed multiple OCP devices on the secondary as long as each is installed per 240.21(C) ___ tap rules.
(C)(4) simply removes any length restrictions {such as the 10 ft in (c)(2)}
provided the provisions of (C)(4) are met.
Table 450.3 (B) note 2 will limit you to six OCPD's
but it states "where secondary protection is required" and if he has primary OCP at 125% then secondary is not required.
