You Said: "NEC 2008 Section 695.1(B)(2) states that pressure maintenance (jockey) pumps are NOT covered by the NEC..."
Re-read that article...it says that this Article (695) does not cover jockey pumps. (my words, not verbatum)
If you look further (2008 Handbook), under 695.5 there is a graphic of a tap for a jockey pump (page 1096), and further 695.6 (C)(1) reference is made to Fire Pump Motors and other Equipment.
The jockey being a tap off of the FP service is common, I cannot recall a jockey being fed from another source.
