One of the important changes in the 2021 edition is a further allignment with the IEC 60079 standards, expecially in terms of equipment suitable for the different classified Locations. Table 18 was added and it is derived from the IEC 60079 standards.
Another update in the 2021 edition is a new definition of Cable and Conductor. Pls refer to the separate article on our site.
In the new CE Code, Rule 2-100 has two changes:
- First is the addition of short-circuit current rating or withstand rating to the list of equipment marking requirements in Subrule (1).
- The second change is the addition of a new inserted Subrule (4) that reads:
“(4) Where the maximum continuous load allowed on a fused switch or circuit breaker as determined in accordance with Rule 8-104 (5) and (6) is less than the continuous operating marking of the fused switch or circuit breaker, a permanent, legible caution marking shall be field applied adjacent to the fused switch or circuit breaker nameplate to indicate the maximum continuous loading permitted for connection to the fused switch or circuit breaker.” There are many installations where it is difficult to confirm the size of the installed conductors without a system shutdown; this new field marking is intended to provide clear notification of the limited loading capabilities for the installation.
If, after reading the article 3 times, you still do not understand what it means, pls contact us, we may help you as well on any electrical application for machinery you are planning to do in Canada.
