Low voltage systems are often ungrounded, which is normal, but non-current-carrying metal parts of equipment associated with low voltage systems are generally required to be grounded if the supply system is grounded. This article reviews NEC requirements for grounding low voltage systems. We will also visit NEC provisions that do not permit these systems to be grounded. READ MORE
