| The fundamental rule of protection against electric shock is provided by the document IEC 61140 which covers both electrical installations and electrical equipment.
| |
| | |
| Hazardous-live-parts shall not be accessible and accessible conductive parts shall not be hazardous.
| |
| | |
| 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
| |
| ** Non-conducting location, out of arm’s reach or interposition of barriers
| |
| ** Equipotential bonding
| |
| ** Electrical separation by means of isolating transformers
