.8 Two end switches on all dampers required for emergency controls (ULC Labelled).
.9 Power wiring and control wiring to stand alone panels and terminal unit controllers.
.1 Generally the Electrical Contractor shall be responsible
for the electrical connections from starters to equipment
motors, and the following: (Refer to Section 15920
for exclusions or additions).
.1 All disconnect switches on lock-out station at motor locations where required by Code.
.2 Remote control on H.O.A. stations where they are not part of a mechanical control system panel.
.3 Power wiring to
line voltage thermostats controlling force flow units and unit heaters, and wiring to
float
devices
for sump pumps, etc.
.4 Power wiring to variable speed devices and from variable speed device to motors, where specified.
.5 Spare 15 amp emergency circuit, one on each floor for controls.
.6 Supply and
installation of the properly sized overload heaters in the magnetic starters and thermal
overload
switches.
.1 All work shall be installed to Division 16 Requirements.
.2 Where there is no alternative to supplying equipment which is not
CSA certified, submit such equipment to
Inspection Authorities for special inspection and
obtain approval before delivery of equipment to site. Such
equipment must be individually identified in the
Contractor's proposal.
.3 Use coded conductors throughout with different coloured conductors for each phase and white wire for neutral.
.4 Low Voltage and Communications Wiring - Size and type of low
voltage control signal wiring shall be suitable for
the service for which it will be put to use and be
the responsibility of this Contractor; minimum wire size #18 AWG.
.5 Identify each wire and cable at every termination point. Identify
all conduits with "neat" colour bands at no more
than 7.5 m intervals and on both sides of walls and
floors.
.6 120V circuits shall be, at a minimum, of #12 AWG RW-90 copper. For
runs over 50 m in length, use #10
AWG-RW90 copper.
.7 All wiring in mechanical rooms and service rooms to be in conduit
or raceway. Provide 600 mm, B-X flexible
connection to input and output devices where required
for servicing or to accommodate vibration.
.8 All communication wiring between stand alone panels and the
Operator Interface shall be installed in conduit.
Wiring from SAPs to TUCs does not have to be in
conduit except in mechanical and electrical rooms, and where
direct access is not available.
.9 All 120V interlock wiring and power supplies for panels to be installed in conduit.
.10 Provide 120V power supplies to all main DDC panels, separately circuited from all other loads.
