Eaton Arrow Hart Locking Connector

The Eaton Arrow Hart AHCL1020C is a straight-blade locking connector rated for 20A at 125/250V. It suits industrial and commercial wiring tasks that require a secure three-pole, three-wire connection. The orange and black nylon housing provides clear visual identification on job sites. Electricians and maintenance crews will find it fits standard L10-20 NEMA configurations.

Capacity and headroom

Accepts conductor sizes from #14 to #8 AWG, giving flexibility for a range of circuit loads up to the 20A rating. The cable diameter range of .38 to 1.00 inches (9.5 to 25.4mm) accommodates common service cords. It runs out of headroom when current exceeds 20A or when wire gauges fall outside the #14-#8 window, so match the breaker and conductor to the device rating.

Build quality and daily use

The nylon body resists impact and chemicals found in industrial environments. Ultra Grip ridges on the housing improve torque when tightening by hand or with gloves. Color-coded orange and black sections speed up polarity checks during installation or troubleshooting. The locking blade design prevents accidental disconnects under vibration or cable strain.

Questions about this item

Will the AHCL1020C accept the #10 AWG conductors I already have in my workshop?

The connector is rated for #14 to #8 AWG, so #10 AWG falls within the allowed range and can be used.

How can I verify the AHCL1020C is wired correctly after installation?

Confirm the three-pole, three-wire layout matches the NEMA L10-20 key tab and test for 125/250V continuity on each pole.

Does the package include a strain-relief clamp or must I buy one separately?

The box contains one locking connector; no strain-relief clamp is included, so purchase one if your cable OD exceeds the 0.38–1.00" range.
