15.) The mechanical protection of fire pump wiring and control wiring.
695.6 (E) Pump Wiring & 695.14 (E) Control Wiring
Occasionally fire pump installations present a circumstance where the fire pump and controls connected thereto are in the same room but only a short distance away from the fire pump controller. Because of the distance, the wiring methods being used are not always chosen from the methods indicated in Sections 695.6(E) & 695.14(E). These wiring methods included in these sections are intended to assure protection of the integrity of the wiring system from adverse conditions. Electrical Metallic Tubing (EMT), often found, is not one of the approved methods.
695.6(E) Pump Wiring.
All wiring from the controllers to the pump motors shall be in rigid metal conduit, intermediate metal conduit, liquidtight flexible metal conduit, or liquidtight flexible nonmetallic conduit Type LFNC-B, listed Type MC cable with an impervious covering, or Type MI cable.
695.14(E) Control Wiring
All electric motor-driven fire pump control wiring shall be in rigid metal conduit, intermediate metal conduit, liquidtight flexible metal conduit, liquidtight flexible nonmetallic conduit Type B (LFNC-B), listed Type MC cable with an impervious covering, or Type MI cable.
