Explains basic requirements for residual current devices (RCDs) on construction and demolition sites according to AS/NZS 3012.
Residual Current Devices help protect people and equipment against electrical shocks caused by indirect contact. RCDs work together with Miniature Circuit Breakers (MCB) or fuses, covering the
Above finished grade or sidewalks, or from any platform or projection from which they might be reached. (If these areas are accessible to other than pedestrian traffic, then one of the other conditions
All final sub-circuits of construction wiring must be protected at the switchboard where the sub-circuits originate by a residual current device (RCD), with a maximum rated residual current of 30mA, that
When low voltage equipment is used on construction sites, precautions must be taken to reduce the risk to an acceptable level.
On a construction site, the temporary distribution board should have RCD protection built in. You must test every RCD before use by pressing the test button, and have them formally tested at
The main electric supply station is the installation/utility interface point where further transmission, distribution and utilization of electrical power, the monitoring and control of such power or equipment
These paragraphs apply to structures that support overhead electric power transmission and distribution lines and equipment. They do not apply to portions of buildings, such as loading docks, or to electric
The references on this page provide information related to electrical in construction including OSHA''s electrical construction regulations, hazard recognition, possible solutions and general resources.
It explains the risks of electric shock and how RCDs can help provide protection against indirect and direct contact shock. The document also discusses fire protection and includes case studies
