Issues for Installation of Meters

The subsequent should also be ensured:

a) Appropriate crimping device should be used for crimping the lugs.

Thimbles should be of appropriate configuration (pin type, fork type etc.) to match along with the terminal block for low current links. For high current terminations, crimping should be used along with cable crimping tools and multiple point crimping should be completed for the lugs used for higher current ratings.

b) If the terminal block is of MS cage clamp type, there is no requirement to use any lugs and the copper cables could be directly terminated at the clamp.

c) The recommended tightening torque must be exerted on the screw to ensure proper tightening of the terminations. It is recommended to use proper tools, equipments for these reasons.

d) Usage of lugs as per the recommendation of manufacturer and ensuring proper crimping will protect the joints from failures.

e) For high current terminations, tensile test and shock test should be performed after crimping the lugs.

f) Where aluminium cable termination is to be completed on copper bus bars or brass studs, bimetallic kind of lugs should be used.

g) A few meters have lower terminal pitch. Since of this, cables foul along with each other while installation. Proper cable size according to the meter rating should be defined.

h) Aluminium conductor cables should be replaced through copper cables for the whole current meters.

i) For indoor meters, the wiring should be completed such in which the cables enter the meter box from the bottom or rear side. This not only is aesthetic, but also avoids the service cable from tampers, etc.
