I'm working on a small T.I. in an existing building. I would like to utilize existing near by circuiting, but I'm wondering under NEC 2008 210.4 if I utilize the existing circuits that are connected to their own 20/1P OCPD do I have to swap out the 1P OCPD for a multi-pole OCPD? 
Thanks in advance for your response.
