The Thomas & Betts Method is Better.
The Thomas & Betts method of installing compression connectors on power cables is
designed to provide a high degree of reliability in electrical wiring. This method allows
electrical workers to make installations with little effort and at a considerable savings
in time. The benefit, of course, is a high-quality connection at a low installed cost.
Step 1
Carefully strip the insulation on de-energized
wires to avoid nicking or cutting conductors
(wire brush if required).
Strip the insulation to the proper length so that conductors
can be fully inserted into the connector barrel.
