Page 11: System Grounding And Bonding
3.2.1 System Grounding and Bonding The performance and safety of any TVSS system is dependent on proper grounding and bonding. Grounding is required primarily for safety. Correct implementation also enhances equipment per- formance. Incorrect grounding can reduce or impede the TVSS's operation. All electrical circuits to the TVSS must include an equipment grounding conductor as required by the NEC and local codes. -
