FAQs
For proper installation, verify cable diameter falls within 0.39-1.20 inches and align the plug with the enclosure opening. Ensure Style 2 grounding is secured and that mounts are tight to prevent micro-movements. Use appropriate wiring torque and follow NEC/CEC guidelines. This approach minimizes contact resistance and ensures reliable protection against ingress in Arktite systems.
