N2  - Australia has an electricity mains supply that differs from those of most countries. Safety standards relating to both the mains supply and mains-powered apparatus also differ. This paper describes the mechanism of electric shock and methods of shock protection - core-balance relays, protected earth-free supplies and equipotential earthing are considered. Australian safety standards as applied to earthed mains-powered apparatus are summarized. Particular attention is given to class A and B treatment areas and electromedical apparatus having a patient circuit. Class A, B and Z patient circuits are described.<p /> <p>Language: en</p>
