Question: An electrician is mounting an outdoor disconnect switch in a location exposed to direct sunlight and rain. The enclosure needs to be watertight and rated for outdoor use. Which IP (Ingress Protection) rating would be a typical minimum for such an application according to CEC guidelines and common practice?
Answer options:
- IP20
- IP44
- IP54 ✅ IP67
Correct answer: IP67

Options like IP20 (fingers/large objects, no water protection) or IP44 (splash-proof, not submersible) are insufficient.
