Question: What type of insulation is required on conductors for a recessed luminaire (pot light) where the connection is made within the luminaire's integral junction box?
Answer options:
- NMD90 rated at 90°C
- Conductors rated for at least 90°C ✅ Conductors rated for at least 150°C if specified by the manufacturer
- Any standard building wire
Correct answer: Conductors rated for at least 150°C if specified by the manufacturer
Explanation: CEC Rule 30-408(2) states that if the luminaire is marked with a required supply conductor insulation temperature rating (often 150°C for high-temperature recessed fixtures), the conductors must meet that rating. If no marking exists, 90°C is the default. The higher potential rating is the key safety concern.
