1.1 This Standard applies to appliance plugs used as components of heater cord sets for use on cord- connected heating appliances rated for use on nominal single-phase system voltages of 240 V and less, designed to be used in dry nonhazardous locations in household and similar applications in accordance with the Canadian Electrical Code, Part I. 1.2 In this Standard, “shall” is used to express…

This Code covers all electrical work and electrical equipment operating or intended to operate at all voltages in electrical installations for buildings, structures, and premises, including factory-built relocatable and non-relocatable structures, and self-propelled marine vessels stationary for periods exceeding five months and connected to a shore supply of electricity continuously or from time…

This Recommendation | International Standard specifies the coded representation of picture information for digital storage media and digital video communication and specifies the decoding process. The representation supports constant bit rate transmission, variable bit rate transmission, random access, channel hopping, scalable decoding, bitstream editing, as well as special functions such as…

IEC 61557-8:2014 specifies the requirements for insulation monitoring devices (IMD) which permanently monitor the insulation resistance RF to earth of unearthed a.c. IT systems, of a.c. IT systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c., as well as of unearthed d.c. IT systems with voltages up to 1 500 V d.c. independent from the method of measuring.…

IEC 61557-9:2014 specifies the requirements for the insulation fault location system (IFLS) which localizes insulation faults in any part of the system in unearthed IT a.c. systems and unearthed IT a.c. systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c., as well as in unearthed IT d.c. systems with voltages up to 1 500 V d.c., independent of the measuring…

1.1 This Standard applies to arc fault protective devices designed to be installed in accordance with the Rules of the Canadian Electrical Code, Part I. 1.2 These devices include arc fault circuit interrupters (AFCI) and devices that incorporate arc fault circuit protection for use on single phase, 120 V, or single phase, two-pole, three-wire 120/240 V alternating current, 60 Hz circuits having a…

1.1 This Standard covers cord connected, direct plug-in and receptacle type SPDs whose primary function is to provide surge protection and that are intended to be marked SPD Type 3 in accordance with Clause 5.2(a). This product may also be used for power distribution circuits. 1.2 This Standard applies to SPDs intended for use on 50 or 60 Hz power circuits over 42 V and not exceeding 600 V. 1.3…

1.1 This Standard applies to uninterruptible power supplies (UPS). The primary function of the UPS covered by this Standard is to ensure continuity of an alternating power source. The uninterruptible power supplies can also serve to improve the quality of the power source by keeping it within specified characteristics. 1.2 This Standard is applicable to movable, stationary, fixed, and built-in…
