CSA C22.2 No. 89-15 (2018): Electrical Safety for Swimming Pool, Spa, and Hot Tub Equipment
Comprehensive Requirements for Equipment in and Around Water Installations
CSA C22.2 No. 89-15 (2018), Electrical Equipment for Swimming Pools, Spas, Hot Tubs and Similar Installations, is the essential Canadian safety standard for electrical products designed for aquatic environments. Developed by the Canadian Standards Association (CSA Group), this standard specifies construction, performance, and marking requirements to mitigate electric shock, fire, and injury hazards. It is referenced by the Canadian Electrical Code (CSA C22.1) and is mandatory for all electrical equipment intended for installation in or adjacent to water bodies such as pools, spas, hot tubs, wading pools, and fountains. This article provides a technical overview of the standard’s scope, critical requirements, implementation aspects, and compliance pathways.
1. Scope and Application
CSA C22.2 No. 89-15 applies to electrical equipment rated 600 V or less that is intended for use with permanently installed or storable swimming pools, spas, hot tubs, and similar water installations. The equipment may be located indoors or outdoors and includes, but is not limited to:
- Pump motors and associated controllers
- Electric heaters (immersion, circulation, and heat pump type)
- Lighting fixtures, junction boxes, and transformer enclosures
- Underwater luminaires and accessories
- Control panels, switches, and timer mechanisms
- Ground-fault circuit interrupters (GFCIs) and related protective devices
- Receptacles, covers, and cord connection kits
The standard does not cover portable cord-connected appliances intended for domestic use (e.g., vacuum cleaners, submersible pumps for small fountains) unless their installation falls within the definitions of a pool or spa. For such cases, other CSA standards (e.g., CSA C22.2 No. 3, No. 68) may apply.
2. Key Technical Requirements
2.1 Bonding and Grounding
Mandatory bonding of all metallic components within 3 m of the pool or spa perimeter is a cornerstone of the standard. The bonding grid must be interconnected using #6 AWG bare copper wire (or equivalent) and must be continuous without depending on conduit, piping, or the equipment grounding conductor. All parts such as ladders, handrails, motors, light fixture mounting brackets, and metal fittings must be connected to the bonding grid.
Bonding Conductor Requirements (Excerpt): For safety, the bonding conductor shall be a minimum of 6 AWG copper or 4 AWG aluminum, and all connections must be made with irreversible connectors (e.g., crimp connectors, bronze clamps). The bonding system must be verified to have a resistance not exceeding 0.1 Ω between any two bonded parts.
Equipment grounding is required for all electrical equipment supplied by branch circuits. The standard references the Canadian Electrical Code (CEC) for sizing of grounding conductors, but adds additional restrictions for underwater equipment where any metallic enclosure must be bonded to the grid regardless of its voltage rating.
2.2 Ground-Fault Circuit Interrupter (GFCI) Protection
GFCI protection is mandated for all circuits supplying equipment covered by the standard. Class A GFCIs (trip level 4–6 mA) are required for:
- All pump motors for pools, spas, and hot tubs
- Underwater lighting fixtures operating at 15 V or more
- Receptacles installed within 3 m of the pool or spa (CEC Rule 68-062)
- Control panels and timers that are accessible without tools
Important: Even 12 V or 24 V underwater luminaires must be powered through an isolation transformer that meets CSA C22.2 No. 66 requirements, and the secondary circuit must be ungrounded and GFCI-protected if accessible from the water. Failure to comply can result in unacceptable voltage gradients in the water.
2.3 Underwater Luminaires and Wiring
The standard distinguishes between wet-niche and dry-niche fixtures. Wet-niche fixtures are designed to be submerged and must be watertight with a permanently attached cord sealed to the fixture body. Dry-niche fixtures are recessed behind a wall or deck and must have a suitable faceplate seal. All lighting fixtures must be marked with their maximum lamp wattage and voltage, and must be tested for thermal protection (automatic reset thermal cutouts are prohibited unless part of a listed system).
| Parameter | Wet-Niche | Dry-Niche |
|---|---|---|
| Housing material | Corrosion-resistant copper alloy or stainless steel | Same, or weather-resistant plastic |
| Lens / globe | Tempered glass, min. 6.4 mm thickness | Tempered glass or high-impact acrylic |
| Sealing method | Gasket + underwater-rated compound | Faceplate gasket + sealing screws |
| Bonded connection | Stainless steel bonding lug integral to housing | Bonding conductor to metal housing |
| Cord type | SO, ST, or SJTW with watertight cord connector | SO, ST, or any approved cable in raceway |
2.4 Transformers for Low-Voltage Systems
Transformers supplying underwater lighting must be isolated (primary to secondary) and comply with CSA C22.2 No. 66 (Low-voltage transformers). The secondary circuit must be ungrounded and protected by an overcurrent device rated at not more than 20 A. For secondary voltages above 15 V but not exceeding 30 V, GFCI protection is also mandatory on the secondary side.
3. Implementation Considerations for Manufacturers
To achieve certification under CSA C22.2 No. 89-15, manufacturers must demonstrate compliance through rigorous testing conducted by an accredited certification body (e.g., CSA Group, QAI, Intertek). Key implementation aspects include:
- Corrosion testing: Salt-spray (ASTM B117) for metallic components used in outdoor or chlorinated environments.
- Strain relief and cord retention: All cord-connected equipment must withstand a 35 lb pull test for 1 minute without displacement of internal connections.
- Thermal testing: Fixtures must not exceed maximum temperature limits for accessible surfaces (typically 60°C for metal, 75°C for plastic) under normal operating conditions.
- Labelling and markings: Permanent marking must include the CSA certification mark, catalog number, ratings (volts, amps, type), water type (pool, spa, or both), and a caution statement regarding bonding.
Tip for manufacturers: Design equipment with a dedicated bonding lug that is clearly identified and isolated from the equipment grounding conductor. This simplifies field installation and reduces the risk of bonding failures. Also, include wiring diagrams that follow CEC Rule 68-400 bonding details.
4. Compliance and Certification Notes
Compliance with CSA C22.2 No. 89-15 is mandatory across all Canadian provinces and territories through their respective electrical codes (e.g., Ontario Electrical Safety Code, Quebec Construction Code Chapter V). The standard is considered a reference standard in Part II of the CSA C22.1 Canadian Electrical Code. Key compliance points include:
- Certification requirements: All electrical equipment for pools, spas, and hot tubs sold or installed in Canada must bear a recognized certification mark from an accredited body. Self-declaration is not permitted.
- Field modifications: Any product that is modified after certification (e.g., replacement of cord, change of lamp type) may void compliance unless re-evaluated by the certifier.
- Inspection by authorities: Enforcement authorities (ESA, BC Safety Authority, etc.) routinely check for CSA marks on pool equipment during new pool installations and renovations. Absence of appropriate marking can lead to de-energization of the equipment.
Non-compliance risk: Equipment that does not meet CSA C22.2 No. 89-15 may still function but poses serious shock hazards. In Canada, uncertified pool equipment is illegal to sell or install, and insurance policies may deny coverage for incidents involving such equipment.
The standard was reaffirmed in 2018 (hence the notation 89-15 (2018)) and incorporates amendments up to that date. Users should always verify that they are referencing the latest edition including any amendments (A1, A2, etc.).

Q: Are there any exemptions for low-voltage equipment (e.g., 12 V DC lighting)?
A: The standard applies regardless of voltage if the equipment is installed in or within 3 m of the pool or spa. However, low-voltage equipment generally requires an isolation transformer and, in some cases, GFCI protection as specified in Section 2.4. The bonding requirements still apply.
