     .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.

            overload switches.

8.5    Conduit, Wiring and Cabling

.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
