Abstract
A lay-in lug (10) with a lug body (12) having a pair of generally parallel, opposed breaker stabs (14, 16) that are engageable in line contacts (44, 46) of a main circuit breaker (48) and securement flanges (20, 22) for attachment of the lug body to an electrical power distribution device. The lug (10) also has a lug cap (30) attachable to the lug body (12) for capture of an electrical cable (42). The lug cap (30) and lug body (12) are preferably formed by extrusion.
Claims16
A lay-in lug comprising:
- a lug body having a pair of generally parallel, opposed breaker stabs and means for attachment of the lug body to an electrical power distribution device;
- and
- a lug cap attachable to the lug body for capture of an electrical cable, where the stabs are directly engageable with line contacts of a main circuit breaker when the lug cap is attached to the lug body.
A lay-in lug comprising:
- a lug body having a uniform cross section with a pair of parallel, opposed breaker stabs, a body flange on each breaker stab, and an anti-rotation and base mount securement for attachment of the lug body to an electrical power distribution device;
- and
- a lug cap having a uniform cross section with a pair of parallel, opposed cap ears, a cap flange on each cap ear that is slidably engageable with the corresponding body flange on each breaker stab, for capture of an electrical cable between the lug body and lug cap, where the stabs are directly engageable with line contacts of a main circuit breaker when the cap flanges are engaged with the body flanges.
A lay-in lug comprising:
- a lug body having a first breaker stab, and means for attachment of the lug body to an electrical power distribution device;
- and
- a lug cap attachable to the lug body for capture of an electrical cable, where the stab is directly engageable with a line contact of a main circuit breaker when the cap is attached to the body.
