What is TAP joint?
Tap, joint (aspiration): A procedure whereby a sterile needle and syringe are used to drain joint fluid from the joint. This is usually done as an office procedure or at the bedside in the hospital. The skin over the joint is sterilized with a liquid.
What is the preferred method for stripping wire?
Bring the wires to a crossed position and make a long twist or bend in each wire. Wrap one end of the wire and then the other end four or five times around the straight portion of each wire. Press the ends of the wires down as close as possible to the straight portion of the wire.
What is the purpose of Y splice?
A Y splice joint, also known as a tap splice, connects a conductor to a running wire.
What are the different electrical wires splice and joint?
There are three main types of electrical joints, also known as splices: The Western Union splice, the tap splice, and the fixture splice.
How do you make a fixture joint?
The first step is to remove the insulation and clean the wires to be joined. After the wires are prepared, the fixture wire is wrapped a few times around the branch wire. The end of the branch wire is then bent over the completed turns. The remainder of the bare fixture wire is then wrapped over the bent branch wire.
When to use a knotted tap or wire nut?
The knotted tap is used where the splice is subject to strain or slippage. When there is no strain, the knot may be eliminated. The wire nut (view A of figure 2-10) is a device commonly used to replace the rattail joint splice. The wire nut is housed in plastic insulating material.
When to use a knotted or plain tap joint?
• This method of wrapping is generally used on small cables because the strands are flexible and all can be wrapped in one operation. f Knotted tap. • This is used where the tap wire is under heavy tensile stress • . f Plain tap joint • This is used where the tap wire is under considerable tensile stress circuit. f Aerial tap.
What’s the purpose of the easy twist wire?
• This is used as a temporary tap usually done in constructions sites. The easy twist will facilitate tap wire movement f Duplex cross joint • This is a two-tap wire turned simultaneously and is used where the two tap wire is under heavy tensile stress f Western Union Short-tie Splice • .
How is a wire nut used to insulate a wire?
The wire nut is housed in plastic insulating material. To use the wire nut, place the two stripped conductors into the wire nut and twist the nut. In so doing, this will form a splice like the rattail joint and insulate itself by drawing the wire insulation into the wire nut insulation.
