13/12/2019 LV SWITCHBOARDS

1. Scope

This Specification details the design and construction requirements for new Main LV Essential and Non-Essential Switchboards (MSBs), Distribution Switchboards (DBs), SDA Boards, Mechanical Switchboards (MSSBs) and UPS Distribution Switchboards and Light and Power Distribution Boards on the Melbourne Airport LV network. It shall be used by Contractors for works at Melbourne Airport.

National standards, international standards and national legislation shall take precedence over this Specification where they present a higher level of service or protection.

1.1 Mandatory and non-mandatory requirements

The following language key describes the requirements of imperative statements within this Specification.

The word:

Shall - describes mandatory requirements

Should - describes non-mandatory best practice recommendations; and

May - describes possible options that are not mandatory or best practice

1.2 Limits of specification

Users of this Specification shall explicitly demonstrate compliance with the APAM LV Design Standards. Compliance shall be demonstrated through:

Adopting appropriate standards and providing explicit reasons for their selection; or

Providing an explicit, evidence based, case study supporting compliance with this specification.

The general statement “in accordance with Melbourne Airport Standards”, shall not be deemed acceptable without further detail.

1.3 Deviation from specification

Where the requirements of this Specification are not able to be met through the design process, a request for deviation shall be made. Requests for deviation shall explicitly state the areas where a proposal does not comply. As a minimum, submissions shall include detailed commentary on:

The reason for deviation from this Specification;

How the deviation complies with all other mandatory standards or regulations; and

Any impacts on safety, reliability, ongoing cost, operability and maintenance.

Deviations from any part of this Standard shall be submitted in writing to the relevant APAM

stakeholders for endorsement before they are implemented or incorporated into a design. Approval of

a deviation from this Standard is not guaranteed and is unlikely to be granted without a compelling

reason. Approval of a deviation shall not constitute approval of the same approach in the future.
