ECN Forum Forums Code Related Discussion NEC & other Code issues "Dwelling Unit" except. applies to PL&P service?

2005 NEC 690.64(B)(2) allows an exception for a "dwelling unit". If I am making load side interconnection to the main distribution panel (MDP) of the PL&P service of a 180 unit apartment building, is the exception allowed. Note: the loads on the MDP are common area lighting, laundry, compactor, etc......no apartments.
