Cover grounded metalwork
Grounded metal parts should be covered with insulating material as much as possible. Very important. For all low voltage cables there should be an additional protection over the insulation. If the cables is outside or located where it may be abused then this outer cable should be tough enough to withstand this abuse in some cases this will mean the cable should armoured. For live elements inside an enclosure this means that the enclosure must be strong enough to withstand the abuse it is likely to suffer in that location.
