Commonly refereed to as a “Jumper”, “Jumper Bar”, or “Terminal Block Jumper” It is a short length or conductor (commonly copper)that is used to connect two or more points in a electrical circuit. Very commonly used in industrial control panels. Are mainly intended for use with specific hardware, such as terminal blocks.

What are terminal block jumpers used for?
Terminal block jumpers are lengths of conductive material used to electrically connect two or more block positions together. They come in various styles such as spade, ring, tubular, sleeve, and pin terminals. The jumpers are also available in various contact materials and finishes.
What is a jumper on an electrical system?
A jumper is a tiny metal connector that is used to close or open part of an electrical circuit. It may be used as an alternative to a dual in-line package (DIP) switch. A jumper has two or more connecting points, which regulate an electrical circuit board.
What is terminal with saddle jumper?
Saddle jumper-compatible terminals typically have a duct in the middle, which receives the metal jumper. Insertable jumpers can be used to connect neighboring or adjacent terminals together. Insertable jumpers are usually crowned connection elements which are attached to the terminal connection points.
Can you cut terminal block jumpers?
NOTE: Jumpers should only be cut with a recommended jumper cutting tool. Please order based on how many terminal blocks you wish to connect and we will cut it for you. If you must cut after purchase, contact us for info on how to do so.
Why jumpers are used in transmission lines?
A jumper is a conductor that is rated to carry full line (load plus capacitive charging) current and is installed to connect line spans on opposite sides of a deadend or a large angle structure. The jumper is installed on each phase of the line and operates at full line voltage.
Why do we use jumpers?
In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. They are typically used to set up or configure printed circuit boards, such as the motherboards of computers.
How do you detect a jumper?
Sometimes thieves steal electricity right at the pole. Stand next to the pole and give it a visual inspection. Jumper cables and hanging wires are all signs that something is amiss. Your pole should look like the other poles in your neighborhood.
Is it OK to bypass a fuse with a jumper wire?
If the jumper wire is of too small a gauge, it may overheat and possibly melt. Never use jumpers to bypass high resistance loads in a circuit. Bypassing resistances, in effect, creates a short circuit. This may, in turn, cause damage and fire.
How do you wire a terminal block strip?
How to wire terminal blocks
- Insert your wire into one side of the terminal block.
- Depending on what style of block you have you will need to insert a terminal screwdriver, loosen the screw or push on the device which allows you to push the wire in.
- Push the wire in and secure the wire in place.
How do Jumpers work?
When you set a jumper, you place a plug on the prongs that completes a contact. In effect, the jumper acts as a switch by closing (or opening) an electrical circuit. Jumpers can be added or removed to change the function or performance of a PC component. A group of jumpers is sometimes called a jumper block .
How many wires can you put in a terminal block?
Feed-through terminal blocks are used to connect two wires together for wire-to-wire connections. This terminal block type has one input and one output contact where two distinct wires are fed into opposite sides of the housing. Like PCB mount versions, these can also be single, dual, or multi-level modules.
How does a spring terminal work?
Spring terminals work in a similar fashion as screw terminals. However, instead of tightening a screw to make a connection with piece of wire, a spring clamps together pieces of metal together. Spring terminals provide an alternative to screw terminals.
What is damper in transmission line?
A Stockbridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines, long cantilevered signs and cable-stayed bridges.
What type of earthing is used to transmission line?
Earthing or Grounding of Distribution Lines
Electrical Earthing is done by connecting the non-current carrying part of the equipment or neutral of the supply system to the ground. For distribution lines, wire earthing is used by low resistance wire known as the earth wire.
How do you jumper a circuit board?
Jumpers are small blocks on a circuit board with two or more pins emerging from them. Plastic plugs containing a wire fit down over the pins. The wire connects the pins and creates a circuit. To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated.
What do you wear with a jumper?
Wear it with jeans, a dress, or dress pants depending on formality. Add accessories to make a fun outfit out of your jumper. Jumpers look great with things like cardigans, belts, and blazers.
What are the types of jumper wires?
Jumper wires typically come in three versions: male-to-male, male-to-female and female-to-female. The difference between each is in the end point of the wire. Male ends have a pin protruding and can plug into things, while female ends do not and are used to plug things into.
How do you connect jumper wires?
Connect the positive end (typically red) of one of the jumper cables to the positive terminal on the dead battery (labeled with a “+” sign). Generally, the battery’s positive terminal is larger than the negative one and could have a cover on it. Attach the other red clip to the positive terminal of the other car.
What is illegal tapping of electricity?
Illegal Use of Electricity. – It is hereby declared unlawful for any person, whether natural or. juridical, public or private, to: a) Tap, make or cause to be made any connection with overhead lines, service drops, or other electric.
How does someone steal your electricity?
Most electrical theft crimes occur through meter tampering, bypassing meters, and tapping power lines. Other less frequent crimes include tapping into neighboring premises, using illegal lines after disconnection, self-reconnection without consent, and electrifying fences.
