Power and Grounding Cables
Installation Check
Ensure the power and grounding cables installation is done in ac-
cordance with the following checks:
1. The power and grounding cables are laid separately from other
cables. If the power and grounding cables are to be laid par-
allel with other cables, then at least a distance of 20 cm is
maintained between them.
2. The cable labels are intact on both sides of power and ground-
ing cables. The labels are attached at almost 2 cm from cable
copper lug.
3. Entire power and grounding cables are made from one material
with no connections in between.
4. A single grounding point on the grounding busbar just connects
to a piece of equipment.
5. Copper lugs on both ends of power and grounding cables are
soldered or pressed firmly.
