    • Aluminum RMC and its associated fittings are fine where installed per Sections 344.10(A)(3) and (B)(2).


    • They must be listed per Section 344.6 but NOT specifically for Classified Locations.


    • Section 501.10(A)(1)(a) and by back reference in Section 501.10(B)(1)(1) specifically permit various forms of RMC and their associated fittings in Classified Locations.


    • Class I, Division 1 boxes and fittings must comply with Section 501.10(A)(3).


    • Class I, Division 2 boxes and fittings only need to comply with Section 501.10(B)(4) with a few limitations as noted previously.


    • Section 500.8(C)(6)(a) does not require boxes and fittings to be specifically marked for Classified Locations.



    Your Aluminum LB is fine in the application as described.
    That should cover the OP.
