This amendment to sub-rule 5) confirms the existing rule that the cable in the air room in a combustible building must be marked FT6 .
The second amendment to Section 12 can be found in Rule 12-020 Wiring Under Siited Floors for Data Processing and Similar Systems. Cable-type hydraulic conduit has been removed as a tax term due to recent changes to Rule 12-1302 allowing the use of cable conduit. transport to be used as a common channel. The main change in Rule 12-020 is to allow a cable no longer than 4.5 meters in length to be used as a data access method for high data floors.

If the roof does not use brackets or other metal fasteners such as shingles, this new rule does not apply. In addition, Subrule 2) allows Class 2 special telephones that do not exceed 30 V open circuit voltage and a thermal test. When Class 2 vehicles are concealed and electric heaters are attached to building walls using screws or other metal supplies, warning signs will also be required in a visible location at the edge of the roof where they are installed. the wire. and on all installed space. he pointed to the ceiling.
Table 19 was first introduced in the EC Code in the sixth edition published in 1953. The original Table 19 was an extension of Table 1 of the 1947 CE Code, which was limited to food in lead, type and maximum temperature allowed. In 1953 Table 19 referred to Section 12. In 1958 CE Code Table 19 was expanded to include Conditions of Use and Trade Names and to include rules within the meaning of Sections 4, 12, 16, 22, 26, 34, 36 and 38.
Over the years, more information was added as the table grew, resulting in the table showing 17 code sections in the 2009 version. Between the 2009 and 2018 editions of the EC Code, legal information was given to section 12. This change gave Section 12 the task of maintaining Table 19. Section 12. This working group meets once a month for 18 months to create the new table 19. The new table 19 is the same as the current table 65. It is easy to use, accurate, small and without information. The task force examined each cable and cable type for correct and incorrect types and uses. In addition, all 37 articles were removed. Some articles were placed in regulations in the main body of the law, others were placed in the articles of Appendix B, and others were deleted. they are old stories. Another good result is that all the information about each type of cable or cable is on the same page, making it easy to use the table.
For example, all information about clean cars (such as the RW90) can be found on the first page of the new Table 19. Table 19 has eight pages. as mentioned below.

Clamps and hoses. Open wiring, also known as switch and pipe, in rules 12-200 to 12-224 has been removed. The switch and conduit conduit was included in the first edition of the Canadian Electrical Code published in 1927. The new installation and wiring arrangement replaced the wire in the 1950 when the 1958 edition of the EC Code required equipment boxes to be connected (then . called establishment). Because the switch and pipe are still in place, the rules listed in 12-204 and 12-206 will continue to provide guidance on whether when connected to existing wiring and piping.

Rule 12-204, which requires trailers to be placed in canals, is amended and read as Rule 12-202.
The 12-300 series of rules for outdoor exposed cables has been updated, limiting the height of two vehicles to 4.5 m and requiring the distance above 4.5 m to be a cable with a soft support or a mounting bracket attached to the walking wire. Additionally, new rule 12-320 implements the wire carrier requirement from rule 30-1116.
The seat belt and seat belt regulations contained in ordinance 12-214 were amended to ordinance 12-514. As part of the move, the law was added to provide guidance on the number of steps and barriers and where they should be placed. The safety knots consist of two boards, one on each side of the safety rope, and the lines are attached to a rope attached to the sides of the legs. On the roof, steps and barriers must be at least 38mm by 38mm and installed to prevent injury by someone stepping on or kneeling on the rope. To assist code users, Figure B12-3 has been added to Appendix B to indicate proper use of steps and precautions.
Rule 12-516 Protection of Cables in Concealed Installations contains an additional clause 2) requiring cables to be installed at least 38mm from the edge in front of springs and brackets that can be installed on drywall. If it is not possible to obtain a clearance of 38mm, a steel of at least 1.3 mm thickness must be fixed in place and must be extended in front of the wire or tree in a covered way. eat the diameter of the wire or cable. a bundle of rope.

Rule 12-518 The protection of cables in exposed installations is further extended by the addition of a new sub-rule (2), allowing the use of conduit or pipe as a mechanical protection screen for non-metallic cables. The edge of the port needs to be fixed or shaped to prevent abrasion damage, and the repair of the port is limited to the percentages specified in Table 8.
To comply with the regulations for non-metallic installation cables, subrule 1) of the rule 12-616 Hidden Armored Cable Installation has been added to the same requirements for shield plates and horizontal bars. In addition, rule 12-510 refers to cable support to rule 12-618 Running cables between boxes, fixtures, etc. replaced by the same requirement of a support distance of not more than 1.5 m on the road and a permit to use the cable. The maximum distance between the cable lugs and the first cable support is changed to the cable armor, which allows up to 600 mm for cables with many commercial connections between 35 and 78 and above 900 mm for a cable and most commercial connections above 78. . .
Table 6, Table 9 and refer to Rule 12-910 Skids and Cables in Beams and Beams contain major changes that should make it easier to ensure the height the number of horizontal beams that can be placed in the tunnel.

The number of tables in Table 6 remains the same. Table 6 of the 2018 CE code table provides the maximum number of vehicles that can be installed in a pipe or pipe. Tables 2021 provide the mm² of single wire and wire to determine the filling of channels and pipes.

Table 9 has been reduced from 16 tables (pages) to 8 tables and two tables on the allowed percentages of 100%, 53%, 31% and 40% for different pipes and pumps.
Let’s take a look at the examples of installing 10 – #14 AWG RW90 insulated 600V wire in a stainless steel enclosure. To determine the size of the bridge, start with Table 6A, which shows that the total cross-sectional area of 10 #14 wires is 88.67 mm². Go to Table 9G now for 40% free refills. The 40% cross-sectional area of the commercially available 16-gauge steel conductor is 80.93 mm², which is not large enough for 10 #14 AWG wire (88.67 mm²). 40% cross-sectional area of 21 large commercial stainless steel bars is 141.6 mm²; This is plenty for ten #14 AWG wires.
Rule 12-2202, Insulated Wire and Wire in Wire Racks, has significant changes. The first is the new information 1) to identify the revised information
