Product Approval Requirements - Ontario amendment and Exceptions

Ontario amendment to CEC Rule 2-022 - Approval requirements for Equipment that is Battery Operated or Connected to a Class 2 Circuit

The OESC Rule 2-022(3) (c) specifies some exceptions to electrical product approval requirements. Electrical equipment does not require approval if it connected to the load side of an approved Class 2 power supply whose power output does not exceed 100 V•A and is operating at less than 42.4 V peak or DC, with an exception of:

  • (i) luminaires*, decorative lighting strings, signs or displays with incandescent or halogen lamps;
  • (ii) luminaires with Light Emitting Diode (LED) lamps;
  • (iii) luminaires, decorative lighting strings**, signs or displays incporporating a ballast with operating voltages greater than 42.4 V peah or dc;
  • (iv) electromedical equipment;
  • (v) equipment or hazardous locations as defined under Sections 18 and 20 of this Code;
  • (vi) equipment that incorporates heating elements.

*The OESC defines a luminaire as a complete lighting unit designed to accommodate the lamp(s) and to connect the lamp(s) to a circuit conductors.

** It is intended by Subrule (3)(c)(ii) and Appendix B note to Subrule (3)(c) that decorative light strings, signs or displays with LED lamps that are connected to approved Class 2 power supplies are not requireed to be approved.

Background and Rationale


  • Luminaires intended for installation on branch circuits not exceeding 600 V require approval.
  • Portable luminaires operating at 120V nominal require approval.

2) A luminaire connected to an external power supply certified and marked as Class 2, meeting the requirements of CSA C22.1 and OESC Rule 2-022(3)(c), requires approval if:

  • A luminaire contains a halogen, incandescent lamp or LED lamp. The complete lighting unit including the power supply requires approval in order to ensure the luminaire enclosure can withstand the heat produces by the halogen or incandescent lamp.

Luminaire diagram

  • A luminaire contains neon lamps. The complete lighting unit, including the power supply, requires approval. The issue is with the starting voltage that ionizes the gas as well as the operational voltage required to maintain the operation of the lamp.

3) A luminaire containing an internal power supply certified and marked as Class 2 (power supply could not be identified without opening the lighting unit) requires the complete luminaire assembly to be approved.

Luminaire Class 2 Power Supply

Peak voltage (Vpk) is the maximum (peak) voltage that the AC signal attains. The most useful way to describe the potential of an AC signal is to use Vrms. Vrms measures AC signals in a way that gives a voltage value that is equal to what the voltage would be if it were converted to a DC signal. Most Volt-Ohm meters will read AC signals in Vrms. To convert to Vrms multiply Vpk by 0.707. To convert back to Vpk multiply Vrms by 1.414.

Although Rule 2-022(3) states that some equipment does not require approval, the equipment still needs to be "acceptable for the particular application" If the equipment presents an undue hazard under the circumstances, an inspector can deem it to be "unacceptable".


Fluorescent and HID Lamps, Not Self Ballasted
There are currently no Canadian product standards for these types of lamps; therefore, these lamps cannot be approved and do not require approval.

Travel power supplies, adapters and plugs

There is currently no Canadian standard that permits certification of electrical products with plugs configuratins (for examples, plugs configuration for European markets) that are not specified in Diagram 1 and Diagram 2 of OESC.

Revenue Billing Devices, Electricity Meters
ESA's Bulletin 6-8-* clarifies that revenue billing devices meters are not required to be approved as per OESC requirements. The Bulletin provides consistent direction with respect to ESA's jurisdiction over revenue billing devices, governed the "Weights and Measures Act" and "Electricity and Gas Inspection Act" and sued by Local Distribution Companies, licensed by the Ontario Energy Board (OEB).

The constitution Act assigns authority for weights and measures to the Federal Government.

The Federal Legislation:

  • Does not require the revenue billing devices to be "approved" as required by the Canadian Electric Code or Ontario Electrical Safety Code; and
  • Does not give ESA any jurisdiction over revenue billing devices, and/or associate Current Transforms (CTs) and Potential Transformers (PTs) associate with the revenue billing device.

Meters and instrument transformers are required to be tested to specifications, which are set out in the Electricity and Gas Inspection Act. These specifications establish design, composition, construction and performance requirements for any meter or instrument transformer. The specification also requires a unique Measurements Canada approval number, as identified in "LMB-EG-07 Specification for APproval of Type of Electricity Meters, Instrument Transformers and Auxiliary Devices".
