	■ Grounding to comply with Underwriters Laboratories (UL) 1459:
	A. An insulated grounding conductor that is not smaller in size and equivalent in insulation
		material and thickness to the grounded and ungrounded branch circuit supply conductors,
		except that it is green with or without one or more yellow stripes, is to be installed as part of the
		circuit that supplies the product or system.
	B. The grounding conductor mentioned in item A is to be connected to ground at the service
		equipment.
	C. The attachment-plug receptacles in the vicinity of the product or system are all to be of a
		grounding type, and the grounding conductors serving these receptacles are to be connected
		to earth ground at the service equipment.
Requirements for	Installation of a telephone or other standard (tip/ring) device in another building requires the
Out-of-Building	following In-Range Out-of-Building (IROB) protectors to protect the control unit and device from
Extensions	electrical surges:
