Fixing of the above components in panel enclosure with terminal blocks, channels, ferrules, thimble, support insulator on bus bar required hard wares, control wiring in 1.5 sq mm single copper wire complete in all respect.

Dismantling of old panel, structure ,damaged components and insulation of the panel at site by making foundation, termination of cable both incoming and out going side ,meggaring of complete panel, including cable connections. This includes cartage ,loading and unloading by crane or heavy labour etc.

Testing & commissioning of panel,as per required parameters with relevant IS . Testing of the panel prior to switching on as follow :- i) Continuity and earth testing ii) Meggaring of all equipments for phase to phase, neutral to body, neutral to earth and phase to earth. iii) Checking for all tightness of nut and bolts. iv) Alignments of doors etc. v) Interlocking tests. All function tests.
