1. Provide:
All control system components, except those supplied as part of packaged equipment controls,
but including all auto sequencing devices, electric relays, safety devices and electrical interlocks
required to accomplish specified sequences. Refer to the electrical motor schedule in the
electrical drawings and/or specification, which delineate the limits of electrical work in Division

All control circuit transformers required for control systems and not supplied by Division 16
including line voltage power connection from indicated outlets shall be included by Division 15.
All wiring shall be copper with RW90 X-Link P.E. insulation #12 minimum size. Wiring is to
be in conduit in all wall spaces and exposed locations as well as in pipe chases, service spaces,
attics, and crawl spaces which are entered for service access. Wiring in suspended ceiling
spaces does not require conduit but shall be neatly installed parallel to building lines using
bridle rings. All wiring installed under this contract shall be plenum rated FT-6 or FT-4, if
approved by all authorities having jurisdiction. Locate wiring away from top or bottom of
ceiling joists or trusses to minimize possibility of accidental damage. Number 18 gauge wire
may be used in Class 2 circuits unless voltage drops are excessive. THHN wire will not be
acceptable. Twisted shielded wiring, minimum of 22 gauge wire shall be used for all DDC or
co-axial communication wiring. Line voltage alternating current wiring shall not be run in the
same conduit, or cabling as DDC wiring.
Use 1m of flexible conduit for all connections to vibrating equipment. Use liquid tight flex cable
and connections where required.
