Grounding and Bonding Equipment

UL 467

1 Scope

1.1 This Standard applies to grounding and bonding equipment for use in accordance with the Canadian Electrical Code, Part I, CSA C22.1, in Canada, the National Electrical Code, NFPA 70, in the United States, or the Standard for Electrical Installations, NOM-001-SEDE, in Mexico.

1.2 This Standard applies to the following grounding and bonding equipment:

a) ground clamps, bonding devices, grounding bushings, water-meter shunts, grounding electrodes, and the like used in a grounding system;

b) equipment for making electrical connections between

i) the grounding conductors used in electrical power systems, non-current-carrying metal parts of electrical equipment, armored grounding wires, metal raceways, and the like; and

ii) grounding electrodes;

c) equipment for making electrical connections between

i) the grounding conductors used in telecommunications systems such as telephone, radio, CATV, network power broadband, and the like; and

ii) grounding electrodes;

d) hospital grounding jacks and mating grounding cord assemblies (for Mexico and the United States, see Annex a);

e) bonding devices for making electrical connections between

i) the hex head of a brass fitting used in a piping system in accordance with 250.104 of NFPA 70; and

ii) the grounding electrodes; and

f) intersystem bonding terminations for connecting intersystem bonding and grounding conductors for other systems in accordance with NFPA 70.

Notes:1) In Canada, “hospital grounding jacks” are not defined in CSA C22.1, Canadian Electrical Code, Part I.2) In Canada, “mating ground cord assemblies” are covered in CSA C22.2 No. 21 and CSA C22.2 No. 42.

Scope

1.1 These requirements cover grounding and bonding equipment for use in connection with interior wiring systems in accordance with the National Electrical Code. These requirements also cover hospital grounding jacks and the mating grounding cord assemblies.

1.2 These requirements cover ground clamps, bonding devices, ground mesh, grounding and bonding bushings, water-meter shunts, armored grounding wire, ground rods, and the like.

1.3 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
