| The fundamental rule of protection against electric shock is provided by the document IEC 61140 which covers both electrical installations and electrical equipment.<br>Hazardous-live-parts shall not be accessible and accessible conductive parts shall not be hazardous.<br>This requirement needs to apply under:
| |
| | |
| *Normal conditions, and
| |
| *Under a single fault condition
| |
| | |
| Various measures are adopted to protect against this hazard, and include:
| |
| | |
| *Automatic disconnection of the power supply to the connected electrical equipment
| |
| *Special arrangements such as:
| |
| | |
| - The use of class II insulation materials, or an equivalent level of insulation<br> - Non-conducting location, out of arm’s reach or interposition of barriers<br> - Equipotential bonding<br> - Electrical separation by means of isolating transformers
