Att10 - Electrical Services Plans

INTRODUCTION
This report is provided by RCA Consulting Engineers with a view to assess the condition of the
existing Electrical services system. Providing recommendations for upgrade and or maintenance of
the system.
A “walk through” visual inspection was conducted on the 9th February 2022 and no testing was
carried out.


OVERVIEW
    •   The site has an existing 100kVA Padmount Substation fed from a property pole located at
        the property entrance.
    •   The site has a separate meter panel with 2 Meters.
    •   The site has a Main switchboard which feeds several sub boards across the site.
    •   The site has Fibre NBN connected in the Shed which houses the MSB.


INSPECTION:

PADMOUNT SUBSTATION

The existing Padmount Substation is 100kVA only which allows for a maximum supply of
approximately 140A 3 phase. The proposed upgrades to site will require a new Padmount
Transformer or Substation to be installed. The existing location would likely prove suitable for a new
PMT but an application to Energex will need to be submitted to confirm suitability and any
additional requirements Energex might have.


MSB & METER PANELS
The existing Meter panels will need to be upgraded when the new transformer is installed to suit
new supply to site. These will need to be CT Supply meters. If the site wishes to install Solar, further
metering will need to be installed to suit this requirement.
The existing MSB will need to be removed and a new MSB installed to accommodate the new
requirements for the site. Having the new MSB near the new Transformer is preferable as it will
reduce the cost of running consumers main as well as reduce the need to run new submains to the
existing Distribution boards currently supplied by the existing MSB. The current location of the
existing MSB would be suitable. Space to allow for would be approximately 1600mm long x 450mm
deep by 2000mm high.
