A feeder cable connector which is similar to a Tweco, but with a more positive locking mechanism which is easier to disconnect.

A camlock, or also cam lock and Cam-Lok, is an interchangeable single-pole electrical connector often used in temporary electrical power production and distribution predominantly used in the North America. Originally a trade name as Cam-Lok, it is now a generic term.

The most common form is the 16 series, rated at 400 amperes with 105 °C terminations. Also in common use is the 15 series (mini-cam), rated at 150 amperes. A larger version is made denoted as the 17 series with ratings up to 760 A. A ball nose version and a longer nose standard version exist-the latter is the most common. Another version is the Posi-lok which has controlled interconnection sequencing to a panel and a shrouded connector body. The early version original connector was hot-vulcanized to the cable body; later versions use dimensional pressure to exclude foreign material from the connector pin area;the tail of the connector insulator body is trimmable to fit the cable outer diameter.

They are generally used where more than 50 A is required or 3 phase temporary connections are needed, and to connect large generators or building disconnects to distribution panels,or for test connections to load bank equipment for generator load certification; special events and the interconnection of entertainment lighting and sound equipment to power sources. They are usually found only in professional environments, where connections are performed by qualified personnel.
