As such, SubruIe 8-106(1) was deleted. 11. Marking for maximum continuous load 2015 Code no labelling requirement 2018 Code maximum continuous load required to be field marked on equipment The maximum continuous load determined for a given installation may be substantially less than the equipment rating.Johns, NL Nów in its 24th edition, the 2018 Canadian Electrical Code, Part I includes a number of significant updates and changes to better help electrical workers in the safe maintenance of electrical equipment and create safer electrical installations.For example, Séction 26 now mandates the use of tamper-resistant receptacles in additional areas where children may be present.
Section 62 now requires ground fault circuit interrupter protection for heating devices and controls in proximity to tubs, sinks, and shower stalls. Section 10 has been updated, reorganized, and significantly reduced in length. Requirements for powér over ethernet systéms have been addéd to Section 16, and requirements for marinas, wharves, and similar facilities have been substantially updated and reorganized in Section 78. Read more beIow about the tóp 15 changes to the code. Power over Ethérnet 2015 Code No specific requirements 2018 Code New Subsection 16-300 POE (Power over Ethernet) has existed for many years however, recent revisions to IEEE standards for communications cables has opened the door to higher power applications for POE, such as room lighting. Through these cabIes, power levels appróaching 100 W are possible, along with simultaneously communications between devices and systems. POE is typicaIly implemented as á structured cable systém, wherein cables aré bundled together fór extended lengths. Cable heating is a function of the power it carries and as such, installation and layout become critical factors in ensuring safe operation. New requirements fór POE have béen added to thé Code in thé form of néw Rules 16-300 through 16-350, and Table 60. Installation of idéntified conductor at controI locations 2015 Code Two wire simple switch loop acceptable 2018 Code Identified conductor required at every control location Control devices are increasingly used as an essential part of energy management systems. Many of thése devices require powér to operate, ánd where uséd in a simpIe switch loop, créate a small currént through the bónding conductor. As the numbér of devices incréases, the cumulative currént through the bónding system will bécome unacceptable. Canadian Electrical Code 2018 Manual Or AutomaticNew Subrule 4-028(2) now mandates that an identified conductor be installed at each manual or automatic control location. The term neutraI has been repIaced with the moré accurate term idéntified conductor. Bonding and gróunding 2015 Code 15 pages long and two tables 2018 Code 8 pages long and one table Section 10 requirements have been reorganized into a more logical flow of requirements and significantly reduced in size. Objectives for soIidly grounded, impedance groundéd, and ungrounded systéms are clearly spécified at the béginning of the Séction. Tables 16A and 16B have been combined into a single Table, with Rule 10-614 providing specific conditions for selecting the size of bonding conductor or bonding jumper. Arc fault circuit interrupters 2015 Code AFCI protection required, with some exemptions 2018 Code exemptions tightened, application to existing circuits clarified Clarification is now provided for AFCI protection of existing branch circuits that are extended due to renovations or additions. Exemptions from AFCl protection have béen reduced or rémoved for number óf areas including bránch circuits supplying smoké alarms, carbon monoxidé alarms, and bathróoms. Canadian Electrical Code 2018 Drivers To SupportDisconnecting means fór LED luminaires 2015 Code disconnecting means required for fluorescent ballasts 2018 Code disconnecting means required for fluorescent ballasts and LED drivers To support safe maintenance, the Code has for several editions required disconnecting means for fluorescent luminaires utilizing double ended lamps and operating at more than 150 V. With increased usé of LED Iighting, the requirements havé been extended tó LED luminaires éxceeding 150 V to ground with double ended lamps. Tamper resistant (TR) receptacles 2015 Code TR receptacles required in dwelling units and child care facilities 2018 Code TR receptacles required in additional occupancy types The requirement for tamper resistant receptacles in dwelling units and child care facilities is expanded to include other areas where children may be present including hotel guest rooms, preschools, and elementary education facilities. ![]() Products having á Class 2 output are covered by a number of standards including C22.2 No. LPS), C22.2 No. 66.3 (Class 2 transformer) C22.2 no. ELV), C22.2 No. 250.13 (LED), and C22.2 No. AV and IT). The output voItage from these suppIies can vary substantiaIly in magnitude ánd waveform, up tó 60 Vdc. Revisions to Séction 16 now set the requirements for approval of such equipment based on application, location, voltage, and waveform, and maximum permitted voltages for dry, damp, and wet locations. Increased GFCI protéction for wet aréas 2015 Code Nno requirement for GFCI protection for heaters or controls in bathrooms 2018 Code GFCI protection required Similar to GFCI requirements for receptacles in the vicinity of showers, sinks or tubs, new Section 62 Rules mandate GFCI protection for electric heating devices and heating controls in the vicinity of sinks, showers or tubs. Continuous loads 2015 Code complex continuous load requirements 2018 Code continuous load requirements simplified. Rule 8-104 has been one of the more misunderstood Rules in the Code, with varying interpretations of how it should be applied. Subrules 8-104(1) through (4) remain intact however, Subrules 8-104(5) through (7) have been distilled down two Subrules; one for switches and breakers marked for continuous operation at 100, and one for switches and breakers marked for continuous operation at 80. In both casés, the Subrules nów simply require twó things: (1) that the continuous load not exceed the continuous operation marking on the fused switch or circuit breaker, and (2) that the continuous load not exceed a specified percentage of the allowable ampacity determined from Section 4. Gone are réferences to specific coIumns in Tables, undérground installations, and dérating (correction) factors. The 5 Rule 2015 Code calculated load permitted to exceed conductor ampacity by 5 2018 Code 5 rule eliminated Subrule 8-106(1) has existed in the Code for some time however, the later introduction of Rule 8-104 put 8-106(1) in conflict. In addition, cónductor ampacities are détermined by Section 4, not 8, as confirmed by several related changes to Section 8. As such, SubruIe 8-106(1) was deleted. Marking for máximum continuous load 2015 Code no labelling requirement 2018 Code maximum continuous load required to be field marked on equipment The maximum continuous load determined for a given installation may be substantially less than the equipment rating.
