The 2024 Code includes significant revisions to requirements for renewable energy systems, including disconnection means and inverter location and a new option to initiate rapid shutdown of photovoltaic systems.
With the targeted increase in electric vehicle sales, electrical infrastructure must safely support charging needs. The 2024 Code adds demand factors for Electric Vehicle Power Equipment (EVSE) and Electric Vehicle Energy Management System (EVEMS) to load calculations for multi-unit buildings and similar dwellings. This will affect the size of the conductors and the safety of the circuits used.
Although the required demand factor for EVSE loads is 100%, this can be reduced when EVEMS is used, allowing less service to customers under certain conditions.
The 2024 Code contains several amendments aimed at increasing electrical safety for residents and staff in health care facilities. A major change is new guidelines for the location, securing and accessibility of circuit power panels in patient care areas. This amendment aligns the code with the objectives of CSA Z8000,

Load branch circuits in intermediate and critical care areas shall be 2-wire circuits, except for those powering multiphase equipment. Recognizing that all areas of patient care must provide the same level of protection, the 2024 Code extends this requirement to circuits in all primary care areas.
Several editions of the Code have required modified containers for residential, childcare, and elementary education settings. The 2024 Code now extends this requirement to primary care areas for the diagnosis, treatment, and care of children.
For many years, the Code required circuit breakers and fuses to be identified with the loads served by such devices. The 2024 code adds a new requirement, clarifying that identification must be updated when circuits or power supplies are added, removed, or modified to an existing panel.
Similarly, the 2024 Code requires that surge devices be rated at the maximum load serving single or multiple dwellings and that the conductor rating is lower than the rating of the surge device.

. To support existing code requirements for the safe maintenance of electrical systems, the 2024 Code now requires a reduction in the time required to clear arcing faults for high-current devices of 1200 A or greater.
The 2024 edition of the code also includes other updates that provide new and revised requirements for the safety of pool, spa and hot tub maintenance workers, protection of outlets in outdoor or wet locations, and wiring, conductors, connections and grounding methods. .
The new code is the result of the work of more than 260 volunteer CSA group members who have dedicated their time and expertise to help maintain a solid foundation for the safe and efficient use of electricity in Canada and the protection of life, property and the environment.
The Ontario government recently announced a major investment in skilled trades and a revamped apprenticeship program that was praised by Skills Ontario. Skills Canada/Ontario will play an important role in this mandate, raising awareness of the opportunities that skilled trades offer to youth.
