Point of Supply and Main Switchboard

• Take photos of the POS e.g. Transformer (including kVA rating plate), Property Pole, Service Pillar, Aerial Service. Take photos of all if more than one POS.

  Media

• Record on the Site Plan provided by QBuild the POS location(s).

• Ergon/Energex Pole Number

• Transformer Number

• Pillar Number

• Service Fuse Arrangement / Capacity

• CONSUMER MAINS: Number of cables X Size (mm2) per phase for existing consumers mains.

• Route length of Consumers Mains

• Number and size and number of spare conduits from point of supply to the MSB

• Take photos of the MSB: • Wide angle showing the MSB location. • Wide angle with the doors closed. • Close-up with the doors and escutcheons open (where assessed as safe to do so and with school permission if a power outage is required). Clearly show each individual item of switchgear (including particularly the circuit breaker amp rating labels and trip settings with pole position labels visible in the same photos), cables, and cable entry points. • Close up on the MSB schedule card(s) Take photos of the Consumers Mains route: • Show the route the mains take e.g. pillar to MSB or Transformer to MSB

  Media

• Take a photo of the Energex / Ergon metering section and the NMI number. NMI number / s

  Media

• Provide copies of available electricity accounts, preferably for a 12 month period, particularly including the latest available that Include the months of February and March. (IF NOT AVAILABLE ON THE DAY, ADVISE ADMIN TO CHASE UP WITH BSM)

  Media

• MSB Manufacturer / Brand

• MSB Current Rating Chassis/Bus Bars IN AMPS

• MSB Type / Current Rating Main Switch CB / LOCKABLE ISOLATOR / BOTH in amps

• MSB Fault Level in KA

• MSB No. Functional Units & Spares

• MSB Switchgear Make/Model

• MSB Max Demand (MDI reading from MDI’s) (Red/ White/ Blue)

• MSB Spot maximum load measurement (Red / White / Blue)

• Create or mark-up existing schematic diagram clearly showing site-wide reticulation. Include protection ratings, cable sizes and approximate cable lengths. Upload to iAuditor when complete.

  Media

• Take photos of the existing submain routes to show where they run. Take photos of Cable Pits: • Lids open showing conduits (only routes to Blocks where AC Units are being installed or upgraded). • Pits in front of or below MSB with the lids open to show conduits.

  Media

• Validate the Site Plan (write on the Site reticulation plan confirming what’s existing to assist with cable length confirmation based on aerial imagery measurements). Where no Site Plan has been provided showing existing reticulation, sketch draw the layout for the site. (Upload to iAuditor when complete)

• Additional Notes

Distribution Switchboard & Submains

• Take photos of the DSB:

• • Wide angle showing the DSB location.

  Media

• • Close up with the doors and escutcheons open (where assessed as safe to do so and with school permission if a power outage is required

  Media

• • Close up of the DSB schedule card. & available switchboard labelling (Fault rating, Board capacity etc.).

  Media

• What level is this switchboard on (where applicable) ?

• DSB Manufacturer / Brand

• DSB Current Rating Chassis / Bus Bars in Amps

• DSB Current Rating Main Isolator in Amps

• DSB Switchgear Fault Level in KA

• DSB No. Poles & Spares

• DSB Max Demand (Measure spot reading) (Red/ White/ Blue)

• Advise what existing air conditioning was on and if any was locked out

• Submain: Fed from (upstream DB name and building name

• Submain: Upstream Submain Circuit Protection (type, rating & trip setting)

• Submain: Cables (type & size) (include earth)

• Submain: Submain Route Length (m)

• Submain: Cable installation (underground/surface)

• Does the DSB contain any of the following issues:<br>- Visible corrosion on either the switchboard housing, chassis, earth/neutral bars or protective device terminals<br>- Insulation failure on any switchboard associated cabling<br>- Eaton Quicklag ELQ-TW MCBs with Green coloured test switch<br>- Insufficient working space at front of DSB (in accordance with section 2.10.2 of AS/NZS3000:2018)<br>- Switchboard door not key lockable/damaged locking mechanism<br>- Insufficient escutcheon panel with exposed terminals/lack of blanking plates available<br>- Visible breakdown of any door seals<br>- Cable joint into DSB main switch (smaller cabling used to connect into main switch terminals – include cable size)<br>- Power/Lighting circuits not protected with appropriate RCD protection (in accordance with section 2.6 of AS/NZS3000:2018)<br>- Mechanical protection over incoming/outgoing cabling within student accessible areas (classrooms predominantly)<br>- IP rating of DSB located externally, or within kitchen/trade training space is equal to, or less than IP44
