on completing the schedule of inspection checklist, what does "presence of earthing arrangements for combined protective and functional purposes." mean?
to tick or not to tick?
someone from IEE said NA my boss said tick but i would like to know what i'm ticking or not!!
 
From wikipedia,

A functional earth connection serves a purpose other than providing protection against electrical shock. In contrast to a protective earth connection, a functional earth connection may carry a current during the normal operation of a device. Functional earth connections may be required by devices such as surge suppression and electromagnetic-compatibility filters, some types of antennas and various measurement instruments. Generally the protective earth is also used as a functional earth, though this requires care in some situations.
