measured from phase to phase and from phase to ground, This requires

3 measurements if one side is grounded and 6 measurements for 3 phase

circuits.

Where splices or terminations are required in circuits rated above 600

Volts, measure insulation resistance of each length of cable before splicing

and or/terminating. Repeat measurement after splices and/ or

terminations are completed.

single cable. When more than one cables are laid in the same trench,

the width of the trench shall be increased such that the spacing

between the cables is 25 cms. and the end cables are at minimum 15

cms. from the side of the trenches. At the turning of the cable route

the trench shall be dug with radius equal to 15 times the cable

diameter.

7.3.2 The trenches shall be cut square with vertical side walls and with

uniform depth. Suitable shoring and propping may be done to avoid
