CSA B44.1:19/ASME A17.5-2019

The purpose of this Standard is to reduce the risk of injury to persons and damage to property from fire and electrical shock. To this end, it is a safety Standard for the design and construction of equipment to be used in conformity with the rules of the applicable elevator and electrical codes (i.e., ASME A17.1/ CSA B44 and CSA C22.1, Canadian Electrical Code, Part I, or ANSI/NFPA 70). This Standard arose from the need to have identical Canadian and U.S. requirements for this equipment, thereby enabling manufacturers to have their products certified by an approved testing laboratory in Canada or the United States and to have the certification ratified for acceptance in either country.

Scope

1.1 The requirements of this Standard apply to the following electrical equipment for elevators, escalators, moving walks, dumbwaiters, material lifts, and elevating devices for persons with physical disabilities (platform lifts and stairway chairlifts):

a) motor controllers;

b) motion controllers;

c) operation controllers;

d) operating devices; and

e) all other electrical equipment not listed/certified and labelled/marked according to another product safety standard or code.

1.2 The electrical equipment covered by this Standard is intended

a) to be connected to supply circuits at a nominal system voltage of 600 V or less;

b) for internal voltages that are not more than 1500 V;

c) for use in non-hazardous locations in accordance with the rules of the applicable electrical codes; and

d) for use in an ambient temperature no greater than 40 °C.

Note: This Standard does not include requirements for equipment intended for use in an ambient temperature above 40 °C. Additional investigation of the equipment will be required when equipment is to be used in ambient temperature above 40°C.

1.3 The object of this Standard is to reduce the risk of injury to persons and damage to property from fire and electrical shock by presenting requirements for the proper design, the good construction, and the high quality of work of the equipment listed in Clause 1.1.

1.4 This Standard does not apply to devices that are rated for connection to extra-low-voltage Class 2 supply circuits as defined in the applicable electrical code.

Note: Extra-low-voltage circuits are circuits that have a voltage of not more than 30 V rms or 42.4 V peak.
