what is certified electrical design?
A certified design is part of the necessary risk management framework. This enables all parties that influence the safety of completed work to be identified – including their responsibilities, liability and accountability.For a design to be considered certified when it is being relied on to install, test, inspect and connect installations it must demonstrate compliance with legislation and electrical safety. The design must also include the following:• The designer must be clearly identifiable on the design, with the date and their signature,• The location, or proposed location, must be on the design,• The design should identify any standard the installation complies with or is intended to comply.Electricity regulations mandate certified designs for high voltage installations and any installation being installed in accordance with Part 1 of AS/NZS3000. The establishment of the design can be made by:• an electrician who will construct the installation,• an electrician independent from the construction,• a competent person,• an engineer.
In compliance with the Electricity (Safety) Regulations 2010; regulations 14 and 58: A design may be certified, and may be relied on for installations work (Regulation 58).
what is an arc flash risk assessment?
An arc flash risk assessment is a calculation performed by an electrical engineer to determine the incident energy found at each location which determines the arc flash boundaries and what personal protective equipment (PPE) must be used by the employee.
What is an arc flash?
• An arc flash is an explosive release of energy that occurs when an electrical current passes through the air between conductors • Arc flashes can happen in Low and High Voltage systems and installations; the severity of which is determined by certain electrical network design parameters and the method and condition in which the system is manufactured and installed
Why is an arc flash risk assessment important?
• Arc flashes can cause serious injuries or death, including horrific burns, loss of sight and hearing • Arc flash risk assessments help ensure compliance with arc flash codes and standards • They help facilitate safe work conditions for electrical workers
What to expect from an electrical asset appraisal service?
An electrical asset condition appraisal is a systematic operational risk management process that evaluates the condition of electrical equipment and installations. It can help with asset management, maintenance, and safety. Benefits • Identify problems early: Detect issues before they cause costly failures• Reduce downtime: Improve asset availability by reducing unplanned downtime• Improve safety: Ensure health and safety requirements are met• Improve efficiency: Reduce energy usage and extend the life of assets• Improve compliance: Ensure compliance with legislation• Support insurance claims: Provide evidence for insurance purposesElectrical asset condition assessments, in essence, involves comparing the current condition of the equipment to its original condition and by also identifying obsolete equipment or items that have exceeded their economical serviceable lifespan. The collected data is then utilised to provide a platform for making informed decisions, facilitating a planning landscape for repairs and ultimately defining asset replacement strategies.
