CAN CSA E61347‑1‑03 (2018): Canadian Safety Standard for Lamp Controlgear

Introduction

CAN CSA E61347‑1‑03 (2018) is the Canadian national adoption of the international standard IEC 61347‑1:2000, including Amendment 1:2000 and Amendment 2:2006. This standard establishes general and safety requirements for lamp controlgear designed for use on supply voltages up to 1000 V a.c. at frequencies up to 50/60 Hz or 1000 V d.c. As the fundamental safety reference for controlgear in Canada, it is referenced by many product-specific Part 2 standards. Compliance with this standard is essential for manufacturers seeking certification under the Canadian Electrical Code (CE Code) and for those aiming to place lamp controlgear on the Canadian market.

Scope and Applicability

The standard applies to all types of lamp controlgear, including:

Inductive ballasts for fluorescent and discharge lamps
Electronic ballasts
LED drivers for solid‑state lighting
Transformers for low‑voltage lamps
Capacitors and igniters forming part of the controlgear

It covers controlgear incorporated into luminaires or stand‑alone units. The standard does not apply to controlgear for motors or general power supplies unless explicitly covered by a Part 2 standard. CAN CSA E61347‑1‑03 is intended to be used together with the relevant Part 2 standard (e.g., IEC 61347‑2‑3 for a.c.‑supplied electronic ballasts for fluorescent lamps).

Important: The standard applies only to controlgear that is permanently connected or provided with terminals for connection to the supply. Battery‑operated internal controlgear is excluded unless specifically addressed in a Part 2 standard.

Technical Requirements

General Safety and Marking

Every controlgear must be designed and constructed so that it can operate safely under normal and abnormal conditions. Mandatory markings include:

Manufacturer’s name or trademark
Model or type designation
Rated supply voltage, frequency, and current
Rated output parameters (e.g., lamp wattage, output voltage)
Symbols for indoor/outdoor use
Overheat protection class (if applicable)

Protection Against Electric Shock

Requirements cover clearance and creepage distances, insulation resistance, and dielectric strength. The insulation system is classified into functional, basic, supplementary, or reinforced, depending on the application. Minimum distances are specified in the standard for different pollution degrees and altitude conditions.

Thermal and Abnormal Conditions

Controlgear must withstand a range of fault conditions without creating a fire or shock hazard. Tests include:

Abnormal operation (e.g., output short‑circuit, open‑circuit)
End‑of‑life tests (e.g., for starting devices)
Thermal endurance and moisture resistance

Table 1 – Key insulation voltage requirements (based on Table 1 of the standard)
Property	Requirement (for basic insulation)
Minimum clearance (≤ 250 V, PD 2)	1.5 mm
Minimum creepage distance (≤ 250 V, PD 2, CTI ≥ 600)	1.5 mm
Dielectric strength test voltage	1500 V a.c. / 2120 V d.c. (basic)
Insulation resistance (min)	5 MΩ (after humidity treatment)
Protective conductor current	≤ 0.5 mA

Tip: Designers should verify that the controlgear’s internal spacing meets the creepage distances required for reinforced insulation when SELV outputs are not fully isolated from mains.

Implementation Highlights

To successfully comply with CAN CSA E61347‑1‑03 (2018), manufacturers should integrate the following into their design and testing processes:

Use of approved components (e.g., capacitors, fuses, thermal protectors) that are themselves certified to relevant CSA standards.
Incorporation of self‑limiting power sources or thermal cut‑offs to meet abnormal condition requirements.
Application of the standard’s climatic categories (e.g., 30/65/21 for temperature/humidity) for material selection and testing.
Testing with the relevant Part 2 standard to cover specific lamp technologies (e.g., IEC 61347‑2‑13 for LED drivers).
Documentation of all deviations and their rationale for certification bodies.

Good practice: Early engagement with a recognized testing laboratory (e.g., CSA Group, Intertek, UL) can streamline the certification process and identify potential compliance gaps before full production.

Compliance and Certification

In Canada, CAN CSA E61347‑1‑03 (2018) is a harmonized standard referenced by the Canadian Electrical Code (CE Code, Part I) for the approval of lamp controlgear. Compliance is typically demonstrated through third‑party certification by an accredited certification body. The certification process involves:

Submission of technical documentation and drawings.
Type testing of representative samples according to the requirements of Part 1 and the applicable Part 2 standard.
Factory inspection and follow‑up audit to ensure ongoing consistency.

Once certified, the product may bear the certification mark (e.g., CSA Mark) and is accepted across Canadian provinces and territories.

Warning: Non‑compliant controlgear can be rejected by electrical inspectors and may lead to product recalls. Always ensure that the latest edition of the standard (including any corrigenda) is used for certification.

Frequently Asked Questions

Q: Is CAN CSA E61347‑1‑03 (2018) identical to IEC 61347‑1?
A: Yes, it is an adoption of IEC 61347‑1:2000+AMD1:2000+AMD2:2006 with national deviations that reflect Canadian electrical code requirements (e.g., ambient temperature ratings). Always check the Canadian preface for specific deviations.

Q: Does this standard cover LED drivers?
A: Yes, LED drivers fall under the scope of CAN CSA E61347‑1‑03 when used for general lighting. The specific safety requirements for LED drivers are detailed in the Part 2 standard IEC 61347‑2‑13 (adopted as CAN/CSA C22.2 No. 61347‑2‑13).

Q: What are the main differences between the 2003 and 2018 editions?
A: The 2018 reaffirms the 2003 edition with minor editorial corrections. The core technical requirements remain unchanged, but users should rely on the 2018 version for the most current reference and to ensure alignment with the CE Code.

Q: Can a product that complies with IEC 61347‑1 be automatically accepted in Canada?
A: Not directly. While the requirements are very similar, the Canadian version includes specific national differences (e.g., supply voltage tolerance, ambient temperature, and marking language). Certification to the Canadian standard is required for market access.
