Off-premises circuit protection
Protection from hazardous voltages and currents is required for every off-premises (out-of-building)
trunk, line, or terminal installation. Both over-voltage protection (lightning, power induction, and so
forth) and sneak-current protection are required. Sneak-current protectors must be either UL-listed or
CSA-certified, or must comply with local safety standards.
