Grounding & Bonding
Grounding the electrical system provides a means in which
conductive equipment is connected to an earth potential via
the grounding electrode. This prevents potential differences
and sparking between conductive equipment and grounded
structures. Together, proper grounding and bonding will:
r Ensure personnel safety
r Eliminate lighting interruptions
r Protect critical equipment
r Meet IEEE, UL® and CSA requirements
r Provide electrical continuity and reliability
Thomas & Betts durable, code-compliant systems, onsite
grounding and bonding training and installation support are
designed to ensure the safe and reliable operation of your
plant’s electrical systems and increase overall equipment
effectiveness.
