Different Types of Cable Lugs and Sizes of Electrical Lugs

Electricians are using different types of cable lugs on the electrical cables that provides strong connection between cable and equipment. There are four types of cable connectors are commonly used in electrical construction. Ring type lug, U type lug and Pin type lug and Boot lace type are the four types of lugs popularly used by electricians.

The component is used for connecting cable to the electrical  equipment. It is designed for easy installation and remove for repairing or maintenance works. It also provides proper cable fixing identity. After fixing lug to the equipment does not occur any problem like spark or cable burning.

There are four type of lugs are used in the building or industrial construction. Ring type is the mostly used lug in the electrical field. Electrician uses ring type in the MCB, MCCB, RCCB, ACB, OCB, LV and 11kv distribution system panels etc. Wherever comes with bolt and nut, it will be used to connect the cable. Pin type is the second most popular lug in the electrical field. We use mostly pin type in TB and its electrical full form is terminal block. Relays, timers, contactor and MCB sides, commonly used U type lugs. For the control and instrument cable, we use boot lace type lug.

Purpose of using : To fixing wire properly without any loose connection.
We commonly using four types of lugs in the industrial areas.

Ring Type Lug

These type of lugs are used in blot & nuts plotted areas. In MCB, MCCB, ACB, OCB and the electrical panel areas we use this type of connectors.

Ring type cable lug sizes: 1, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 90, 120 (Diameter of the hole is depends on bolt size such as 8 or 10)

Available insulation colors: Red, yellow, blue and black.

U Type Lug

These type of lugs are used in the relays, timer, contactor and MCB areas.

U type cable lug sizes: 1, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 90, 120

Available insulation colors: Red, yellow, blue, black and white.

Pin Type Lug

Pin type of lugs are used in Terminal blocks.

Pin type cable lug sizes: 1, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 90, 120

Available insulation colors: Red, yellow, blue and black.

Boot Lace Type

Boot type connectors are mostly used for control and instrument cables.

Boot lace type cable lug sizes: 1, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 90, 120

Available insulation colors: Red, yellow, blue, black and white.

Crimping Tool

Crimpers are used to make cold weld joints between two wires or a wire and a connector, such as connectors.
Mostly we using two types of crimping tools in construction areas.

• Hand crimper
• Hydraulic crimper
