Pad Mounted Power Supply Equipment
Equipment enclosures shall be trial fitted squarely and symmetrically on the concrete pad prior to drilling for
concrete inserts. Drilling locations shall be marked to maintain this alignment.
A neoprene gasket shall be attached squarely and symmetrically on the bottom channel of the enclosure prior
to installation, with holes for mounting bolts drilled where necessary. Anchor bolts shall be secured in place in
the locations shown in the manufacturer's instructions or where bolt holes have been provided.
614.07.02
Pole Mounted Power Supply Equipment
Supply control cabinet assemblies shall be mounted securely on poles using stainless steel strapping.
Rigid PVC conduit and fittings shall be installed on wood poles using PVC coated pip straps with galvanized
lag screws at 1.5 m maximum centres. Installation on metal or concrete poles shall be done using stainless
steel strapping at 1.5 m maximum centres. The conduit system shall be installed in straight lengths to follow
the taper of the pole. Offset bends shall be used where required to avoid pole attachments and shall be kept
free of kinks or scorch marks.
Cabinets shall be accurately drilled to accept bolt-on weatherproof meter hubs for top entry or terminal
adapters for bottom entry. A meter socket, acceptable to the Supply Authority, shall be installed where
indicated in the contract.
614.07.03
Cable and Fuse
Cables, terminations and connections shall be installed in accordance with the requirements of OPSS 604.
Service cables, from the point of service connection to the main disconnecting means shall meet the
requirements of the Code.
High voltage fuses shall be approved by the Supply Authority prior to installation.
614.07.04
Grounding
All pad mounted equipment shall be grounded by means of ground wire jumpers connected between the
equipment ground bus and the exterior ground grind. Lighting arrestors shall have the ground cable
connected securely to the equipment ground bus. The neutral bus of the main disconnecting means or the
secondary neutral terminal of the transformer shall be grounded.
In supply control cabinet assemblies, the system ground wire and the service ground wire shall be connected
to the neutral bus.
All grounding work shall be carried out in accordance with the requirements of OPSS 609.
614.07.05
Photoelectric Controllers
Photoelectric controllers shall be installed on poles with twist lock mounting adapters and brackets. Brackets
shall be mounted on metal or concrete poles with stainless steel strapping or on wood poles with galvanized
lag screws. The photo-conductive cell window shall be set to face in a northerly direction but away from any
nearby light sources.
