Question:
What is the grounding requirement for TeleCom equipment? IE: can I connect a grounding clamp to an electrical conduit that is bonded to a grounded power panel, with a copper conductor to a grounding bar for our TeleCom equipment?

Answer:
Hey John thanks for your question. If an intersystem bonding termination exists then it must be used as stated in 800.100(B)(1). The requirement to install an intersystem bonding termination was added in the 2008 NEC. If an intersystem bonding termination does not exist then another connection point must be used as stated in 800.100(B)(2). It cannot be any metal raceway but could be a service raceway as stated in 800.100(B)(2)(4).
