📦
Lower panel density but expanding automated conveyor systems and EV charging infrastructure add new study requirements.
View guide →
🏥
Essential services, UPS and generator systems, aging infrastructure in older hospital buildings — critical continuity requirements.
View guide →
🖥️
High-availability electrical systems with dual-path distribution, UPS, switchgear, and generator transfer — specialized PPE considerations.
View guide →
💧
Municipal and industrial water facilities with large pump motor MCCs, variable humidity environments, and public safety obligations.

Regardless of industry, any Ontario employer with electrical equipment energized above 50 volts where a worker may need to perform work within the arc flash boundary is required to have a current arc flash study under CSA Z462. The study must be updated every five years or after any significant change to the electrical system.
