Frequently Asked Questions
Who should use KL-400SFBK and why?
Lighting technicians, electricians, and power distribution professionals working with 400 A temporary power systems will benefit from KL-400SFBK. Its black housing provides instant visual phase identification, while the Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 °C ensures durability in demanding field conditions.
What voltage and amperage is KL-400SFBK rated for?
KL-400SFBK carries a maximum rating of 400 A and 600 V AC/DC. It accepts wire gauges from #6 to 4/0 AWG, making it suitable for the conductor sizes typically used in 400-amp power distribution circuits.
Why choose the black version of the K-LOK 400 A female panel mount receptacle?
Under North American NEMA/NEC conventions, black identifies Phase A (L1), making it the go-to choice for single-phase circuits and the default lead in three-phase systems. In IEC regions, black denotes Phase B (L2). Choosing KL-400SFBK in black ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.
Is KL-400SFBK UL / UL / UL / cUL Listed and what does that mean?
Yes. KL-400SFBK is UL / UL / cUL Listed under File Number E332947, meaning it has been independently tested and certified to UL 1691 safety standards by a Nationally Recognized Testing Laboratory. This certification is required for professional power distribution in most North American jurisdictions.
What industries commonly use KL-400SFBK?
KL-400SFBK is widely used in rental house and staging company inventories serving diverse entertainment clients. Its 400 A / 600 V AC/DC rating, combined with CAM-type universal compatibility and black phase coding, makes it a versatile choice across the entertainment, construction, and industrial sectors.
What makes KL-400SFBK suitable for permanent installations?
Unlike inline connectors designed for repeated connection and disconnection, KL-400SFBK 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.
