Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

UEENEEG007B Select and arrange equipment for general electrical installations

Course Description

This unit covers the planning of circuit and equipment for electrical installations where standardised arrangements for service and Current Transformers metering equipment are used, not exceeding 400 A per phase. This encompasses schemes for protection of persons and property, correct functioning, compatibility with the supply, arrangement of circuits, metering and control, cable route planning, specifying type and rating of switchgear, controlgear, protection devices and wiring based on calculated and deemed-to-comply solutions and planning documentation.


National Codes, Titles, Elements and Performance Criteria

National Element Code & Title:

UEENEEG025B Plan electrical installations with a LV demand up to 400A per phase

Element:

1. Prepare to plan electrical installations.
2. Arrange installation circuits, control and metering.
3. Specify cables, protection and switchgear.
4. Document electrical installation plan.

Performance Criteria:

1 1.1 OHS risk control measures and procedures for carrying out the work are followed.
1.2 The extent and nature of the electrical installation is determined from job specifications.
1.3 Safety and other regulatory requirements to which the electrical installation shall comply are identified, obtained and understood.
1.4 Electricity tariffs required are discussed with appropriate person(s) to ascertain control and metering needs of the installation.


2 2.1 Circuits are arranged to ensure safe and functional operation of the installation.
2.2 Circuits are arranged to comply with technical standards and job specifications and requirements.
2.3 Control and metering of the installation is arranged in accordance with regulatory and local requirements and consumer needs.
2.4 Earthing is arranged to comply with the standards and local energy supplier’s requirements.


3.1 Fault levels at each relevant point of the installation are determined from calculations and/or information from the local energy supplier’s.
3.2 Suitability of the wiring systems selected is determined to meet requirements for protection against environmental factors and job specifications.
3.3 Cable conductor sizes are determined to meet current-carrying capacity requirements and voltage drop and fault-loop impedance limitations and short
circuit performance.
3.4 Protection methods and devices are specified to meet co-ordination requirements for overload and short-circuit protection.
3.5 Switchgear and control gear are specified to meet fault levels, current, voltage and IP ratings and functional requirements.
3.6 Earthing system components are specified to meet requirements of the earthing system used.
3.7 Evidence is obtained that electrical equipment selected complies with safety requirements.


4.1 Equipment specified for the installation is documented together with supporting calculations in accordance with established procedures.
4.2 Electrical installation arrangement, equipment locations, cable routes and schedules and requirements are documented in accordance with established procedures and forwarded to appropriate person(s).

Overview of Assessment

This course will be assessed through a range of classroom based  exercises, assignments and progressive tests.


Assessment Tasks

 Assessment task 1 ( Project 100%)
 Project to produce a plan and electrical schedule of electrical installations with a LV demand up to 400A per phase of the metering, erathing , protection and power requirements for the installation accordance with the relevant Australian Standards, most notably AS/NZ1102, AS/NZ 3000 and AS/NZ 3008.
Particular emphasis in general installation planning process will be on:
aA. Arranging electrical installations to comply with control, metering, safety and other regulatory and functional requirements.
B. Specifying appropriate type and size of cables.
C. Specifying protection methods and devices that meet co-ordination requirements for overload and shortcircuit protection.
D. Specifying switchgear and control gear that meet fault level, current, voltage and IP ratings and functional requirements.
E. Selecting appropriate earthing system components.
F. Documenting installation plan, specifications of equipment, equipment locations, cable routes and schedules and supporting calculations.
G. Arranging electrical installations to comply with control, metering, safety and other regulatory and functional requirements.
