•Cleat wiring can’t be use for permanent use because , sag may be occur after
sometime of the usage .
•In this wiring system , the cables and wiring is in open air , therefore , oil , steam ,
humidity smoke , rain , chemical and acidic effect may damage the cables and wires .
•It can be only used on 250/440 volts on low temperature .
•There is always risk of fire and electric shock .
•It can’t used in important and sensitive location and places .
•It is not reliable and sustainable wiring system .

13. Casing and capping wiring
This system of wiring is suitable for low voltage insulation , in this wiring
cables like vulcanized rubber, insulated cable& or plastic insulated cables are
used and carried within the wood casing enclosures . The wood casing wiring system
shall not be use in damp places, unless suitable precaution are taken.
A rectangular strip of wood called capping having some width as that of casing
is fixed over it . Both the casing and the capping are screwed together at every 15 cam
casing is attached to the wall .

14. Advantages of casing and capping
