CSA C22.2 No. 250.570:16 (R2020) is a standard that provides specific requirements for track lighting systems. The standard applies to both wall and ceiling-mounted track lighting systems, rated 347 V, 40 A max. It covers various lighting sources including incandescent, fluorescent, light emitting diodes (LEDs), and high-intensity discharge (HID) lighting sources. The systems are intended to be installed in non-hazardous, dry locations according to the Canadian Electrical Code, Part I.

The standard also covers plug- and cord-connected track lighting systems rated 120 V. Additionally, it applies to permanently connected incandescent or LED lighting systems supported in free air, employing bare conductors. The power supply for supplying luminaire head assemblies may have one or more secondary output circuits operating at up to 30 V rms or 42.4 V peak or dc, and less than 240 V•A. It also includes provisions for extra-low-voltage suspended ceiling grid systems that operate at 30 V rms or 42.4 V peak, or less, and are connected to Class 2 power supplies.

Furthermore, the standard specifies that lighting tracks should not be connected to a branch circuit protected by overcurrent devices rated or set at more than 15 A in dwelling units, 20 A in other than dwelling units with an input voltage not exceeding 347 V nominal, or 40 A in other than dwelling units with specific types of luminaires.

The units of record for this standard are in SI units, with values given in parentheses for information and comparison purposes. This standard is intended to be used together with the applicable clauses of CSA C22.2 No. 250.0 and its subsequent revisions.
