This National Standard of Canada is based on International Standard CEI/IEC 61000-3-3:1994 +A1 :2001. 1 Scope This part of IEC 61000-3 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods…

1 Scope 1.1 General This Standard specifies requirements for thermostat models intended for line-voltage (120 to 240 V) switching of a controlled resistive heating load. It includes single- and double-pole thermostats that control their load by fast or slow ON/OFF switching. The models covered by this Standard are as follows: (a) wall-mounted line-voltage thermostats; (b) built-in line-voltage…

1 Scope 1.1 This Standard specifies the requirements for three-phase, pad-mounted distribution transformers, consisting of a transformer and a cable entrance compartment with provision for separable insulated high-voltage connectors, intended primarily for operation by electric utilities on three-phase underground distribution systems having primary voltages as shown in Clause 4.6. Note:…

1 Scope 1.1 This Standard specifies the electrical requirements for safe interconnection of inverter-based micro-distributed resource (micro-DR) systems to low-voltage systems connected to distribution systems. The output of these systems is limited to 600 V (nominal) or less (single or three phase). 1.2 Intentional islanding conditions and interconnection to secondary networks are not…

1 Scope 1.1 This Standard applies to oil-fired forced warm-air heating appliances for installation in mobile housing and recreational vehicles, irrespective of the heating capacity or the type of burner used. 1.2 This Standard applies to appliances with fuel supplies that may be located remotely or at the appliance. 1.3 In CSA Standards, "shall" is used to express a…

This National Standard of Canada is based on International Standard CEI/IEC 60335-2-13:2002 +A1 :2004 edition 5.1, 2004-07. 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric deep fat fryers, frying pans and other appliances in which oil is used for cooking, and intended for household use only, their rated voltage being not…

1 Scope 1.1 This Standard specifies requirements for an occupational health and safety management system (OHSMS). This Standard is applicable to an organization of any size or type. This Standard is intended to address occupational health and safety. It is not intended to address product and services safety. 1.2 In CSA Standards, "shall" is used to express a requirement, i.e., a…

This National Standard of Canada is based on International Standard CEI/IEC 60335-2-2:2002 +A1 :2004. 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric vacuum cleaners and watersuction cleaning appliances for household and similar purposes, including vacuum cleaners for animal grooming, their rated voltage being not…

1 Scope 1.1 This Standard covers the features of three-phase submersible transformers rated 75 to 3000 kV.A. Note: For details not covered herein, reference should be made to CSA C2.1. 1.2 This Standard applies only to three-phase distribution transformer units intended for use in a ventilated vault or enclosure below grade level, with all terminations and accessories cover mounted, or nearly…

1 Scope 1.1 This Standard covers the features of single-phase submersible transformers rated 25 to 333 kV'A. Note: For details not covered herein, reference should be made to CSA C2.1. 1.2 This Standard applies only to single-phase distribution transformer units intended for use in a ventilated vault or enclosure below grade level, with all terminations and accessories cover mounted, or…
