8. All terminated conductors shall be labeled as specified prior to final terminations being
done. Any conductor that is de-terminated for any reason shall be re-tested. All
associated controls, if tested before, shall be re-tested.
B. SINGLE CONDUCTORS: Conductors shall be continuous from outlet to outlet and no splices
shall be made except at outlets. Sufficient wire shall be left at outlets to make connections to
equipment without straining. Light switches and receptacles shall be connected with pig tails
and crimp on connectors.
C. GROUND CONDUCTORS
1. Conduits and other raceway shall contain an insulated equipment grounding conductor
whether the raceway is metallic or not. Conduits, motors, cabinets, outlets, and other
equipment shall be properly grounded in accordance with National Electrical Code
requirements. Where ground wire is exposed to mechanical damage, install wire in rigid
aluminum conduit. Bond each end of each of the conduit to the ground system. Make
connections to equipment with solderless connections. All connections to ground rods
shall be of the fused type utilizing an exothermic welding process.
2. Ground metallic material, including but not limited to metallic raceway, metallic boxes and
metallic enclosures. Where metallic material is not connected by raceway to a solid
ground, connect the metallic material to the largest equipment grounding conductor which
it houses. Clean the metal surface under the grounding lug to bright metal. Grounding
connections to motors shall be to the grounding stud which shall be threaded into the
stationary frame; Use Burndy KC Servit, or approved equal. The ground wire shall not be
lugged to a mounting bolt.
3. Ground wire shall be uninsulated tin plated copper sized as shown on the plans in all
cases where a single ground wire is indicated to be installed in a conduit with no other
conductors in the conduit, or where the ground wire is directly buried in earth or concrete.
In all other cases, insulate ground wire with green insulation as specified for low voltage
wire. Provide and size bonding conductors in accordance with the National Electrical
Code.
4. Provide a bare tinned copper ground conductor the entire length of the cable tray shown
on plans, existing and new. Bond each end of the tinned copper ground conductor to
each section and to every enclosure served by the conductors in the cable tray system.
