Frequently Asked Questions
Who should use KL-400SMW and why?
Lighting technicians, electricians, and power distribution professionals working with 400A temporary power systems will benefit from KL-400SMW. Its white housing provides instant visual phase identification, while the Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius ensures durability in demanding field conditions.
What voltage and amperage is KL-400SMW rated for?
KL-400SMW carries a maximum rating of 400A and 600V AC / 250V DC. It accepts wire gauges from #6 to 4/0 AWG (UL evaluated with 4/0 AWG), making it suitable for the conductor sizes typically used in 400-amp power distribution circuits.
Why choose the white version of the K-LOK 400A male panel mount inlet?
White is universally recognized in North America as the Neutral conductor per NEC conventions. Using a dedicated white connector for neutral runs eliminates guesswork during setup and teardown, reducing the risk of miswired circuits. Choosing KL-400SMW in white ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.
Is KL-400SMW UL listed and what does that mean?
Yes. KL-400SMW is UL Listed under UL File Number E332947, meaning UL has independently tested and certified it to UL 1691 for the United States. The listing covers the United States.
What industries commonly use KL-400SMW?
KL-400SMW is used across live events and touring, film and broadcast, rental and staging inventories, and industrial temporary power. Its 400A / 600V AC / 250V DC rating, combined with CAM-type universal compatibility and white phase coding, makes it a versatile choice across the entertainment, construction, and industrial sectors.
What makes KL-400SMW suitable for permanent installations?
Unlike inline connectors designed for repeated connection and disconnection, KL-400SMW is engineered for fixed mounting. Its threaded stud and mounting-hole pattern lock the connector firmly to the enclosure, preventing loosening under vibration - critical for touring racks and permanently installed distro systems alike.
