K-LOK 150A Mini-Cam single-pole cam-type connectors are built for crews who need fast, dependable temporary power connections without guesswork. Rated up to 150A at 600V maximum, the system covers a wide #8 to #2 AWG cable range (outside diameter up to 13.60 mm) so you can standardize terminations across common feeder sizes. The connector uses double set-screw termination and includes extra longer set screws for smaller cables, reducing rework and "almost fits" situations in the field. A POM (polyoxymethylene) insulation ring described as 2x longer than competitors fully covers the brass contact during handling and mating, while a visible raised arrow indicator supports fast, correct alignment on every connection. The Santoprene (TPV) body is UV-resistant and rated to 105 degrees Celsius, with an engraved cut-off identification mark for cleaner builds. Compatible with other brands of 150A cam-type connectors.*

Feature | Why It Matters in the Field |
|---|---|
2x longer POM insulation ring | The POM (polyoxymethylene) insulation sleeve fully encompasses the brass contact, described as two times longer than competitor designs. This reduces exposed-contact risk during handling and mating, giving crews better insulation coverage exactly where they grab and connect. |
Double set-screw termination with extra long set screws | Two set screws secure the conductor from both sides for a balanced grip. Extra longer set screws are included for smaller cable sizes (#8 AWG), eliminating the "almost fits" problem and reducing field rework when cable gauges vary across a project. |
Raised arrow alignment indicator | A visible, molded arrow on the connector body shows correct mating orientation at a glance. Prevents reverse-polarity errors in high-pressure, low-light environments where mistakes cost time and create safety risk. |
Tension hole anti-loosening design | A dedicated tension hole feature helps reduce loose mating over repeated connection and disconnection cycles. This matters on rental fleets and high-turnover event sites where connectors see hundreds of mate/unmate cycles per season. |
UV-resistant Santoprene body with engraved cut-off ID | The TPV body compound is rated to 105 degrees Celsius and resists UV degradation, oil, and common industrial chemicals. The engraved cable cut-off reference line gives every technician a consistent cable preparation reference, reducing variability across crews. |
Non-conductive POM retaining pin | Locks the contact firmly in position without creating accidental current paths. POM is non-conductive and corrosion-resistant, eliminating metallic failure modes in wet or humid environments. |

K-LOK 150A requires no special tools for field assembly and disassembly. Follow the steps below for the correct termination procedure. Inline and panel mount installations use different processes.

1. Measure the cable jacket diameter and compare with the connector body.
2. Cut the cable jacket at the groove that matches the jacket diameter.
3. Strip the conductor to the required gauge length and push the cable through the boot.
4. Wrap strain relief wire around the cable jacket near the end and twist tightly.
5. Squeeze wire ends together and bend parallel to the cable. Trim stray wire flush.
6. Wrap copper shim tightly around the conductor strand and strain relief wire.
7. Insert the wire bundle into the brass contact as far as possible.
8. Tighten the double set screws using a hex wrench. Use extra long set screws for #8 AWG cable.
9. Pull the boot cover over the contact.
10. Align the positioning hole and tighten the retaining pin.

1. Remove the nut and washer from the threaded post on the connector body.
2. Screw the connector onto the panel through the panel cutout.
3. Fit the terminal over the threaded post from the rear of the panel.
4. Refit the washer and nut onto the threaded post. Tighten securely. Do not over-torque.
For detailed strip lengths, set-screw torque values, and inspection checklists, download the Installation and Termination Guide (PDF).
Can I disconnect a K-LOK 150A connector while the circuit is live?
No. K-LOK single-pole connectors are not rated for load-break disconnection. Pulling a connector while current is flowing can create an electrical arc that damages the contact surfaces, degrades the insulating housing, and poses a serious risk of burns, electrical shock, or fire. Always de-energize the circuit at the breaker or distribution panel, verify it is dead using a voltage tester, and only then disconnect. This applies to both inline and panel mount configurations.
Will K-LOK 150A connectors mate with other brands of 150A cam-type connectors?
K-LOK 150A connectors are designed to be compatible with other brands of 150A cam-type connectors, so you can introduce K-LOK into an existing power distribution system without replacing everything at once. If you are running a mixed fleet or specifying K-LOK alongside another brand, contact KUPO for the cross-compatibility statement document, which lists confirmed mating configurations and any pairings to avoid. *Compatibility is based on dimensional interchangeability of the cam-type interface. Always verify mating suitability for your specific application.
Is K-LOK 150A UL listed?
K-LOK 150A connectors are UL/cUL certified per documentation, tested to UL 1691 (Standard for Safety for Cam-Type, Locking-Type Separable Connectors) and CSA C22.2 No. 1691. They carry a NEMA Type 3R environment rating for outdoor use. You can reference the certification in bid documents and spec packages. For a compliance pack with certificate copies, contact KUPO.
What cable types and sizes are supported?
K-LOK 150A accepts #8 to #2 AWG conductors with an outside diameter up to 13.60 mm. For smaller cables at the #8 AWG end of the range, extra longer set screws are included to ensure a secure grip on the smaller diameter. This eliminates the need for adapter sleeves or improvised workarounds when your cable gauge varies across a project. Copper conductors only.
What is the difference between 150A and 400A K-LOK connectors?
The 150A Mini-Cam family is physically smaller and designed for lighter-duty temporary power applications with #8 to #2 AWG cable. The 400A family handles #6 AWG to 4/0 AWG and is built for high-current feeder runs. Both families share the same design philosophy: brass contacts, Santoprene body, POM retaining hardware, double set-screw termination, and UL/cUL certification. Choose 150A when your circuit load and cable size fall within the Mini-Cam range. Choose 400A when you need higher ampacity or larger cable accommodation.
Can I use K-LOK 150A connectors outdoors?
Yes. K-LOK 150A connectors carry a NEMA Type 3R environment rating, meaning they are designed for indoor or outdoor use with protection against falling dirt, rain, sleet, snow, and external ice formation. The Santoprene body compound is UV-resistant and rated to 105 degrees Celsius. These connectors are widely used in outdoor entertainment power distribution, construction site temporary power, film and television location shoots, and generator-to-distribution connections.
What makes the insulation ring design different from other 150A connectors?
The K-LOK 150A POM insulation ring is described as 2x longer than competitor designs, fully encompassing the brass contact where crews grip and mate the connector. This extended coverage reduces the risk of accidental contact with live conductor surfaces during insertion and removal. The POM material is non-conductive, moisture-resistant, and maintains its dimensional stability across the operating temperature range.
Do I need special tools to assemble K-LOK 150A connectors?
No. K-LOK 150A connectors are designed for tool-simple assembly. Inline connectors require only a wire stripper and a standard screwdriver or hex wrench for the set screws. Panel mount receptacles require the same plus a wrench for the mounting nut. No hydraulic crimpers, proprietary dies, or brand-specific tooling are needed. This keeps your crews moving fast during load-in and makes field re-termination practical without specialized equipment.
