Enclosures for electrical equipment, environmental considerations
Scope:
1.1
This standard applies to enclosures for electrical equipment intended to be installed and used in nonhazardous locations in accordance with the Canadian Electrical Code, Part I, CSA C22.1, the provisions of the National Electrical Code, NFPA 70, and the provisions of Mexico's Electrical Installations, NOM-001-SEDE, as follows:
a) Enclosures for indoor locations, Types 1, 2, 5, 12, 12K, and 13; and
b) Enclosures for indoor or outdoor locations, Types 3, 3X, 3R, 3RX, 3S, 3SX, 4, 4X, 6, and 6P.
1.2
This standard covers additional environmental construction and performance requirements for enclosures. The general requirements for enclosures are contained in CSA C22.2 No. 94.1, UL 50, and NMX-J-235/1-ANCE (See Annex B, Ref. No. 10) or the end-use product standards that are to be used in conjunction with this standard.
1.3
This standard does not cover the requirements for protection of devices against conditions such as condensation, icing, corrosion, or contamination that may occur within the enclosure or that may enter via conduit or unsealed openings.
1.4
Where an individual product standard contains requirements that are at variance with those of this standard, the requirements of the individual product standard take precedence.
