[0m:17s] Also, sometimes referred to as a jumper bar or terminal block jumper, a jumper is typically a short length of conductor, commonly copper, that is used to connect two or more points within an electrical circuit.

What is the purpose of jumper wire?
Jumper wires are electrical wires with connector pins at each end. They are used to connect two points in a circuit without soldering. You can use jumper wires to modify a circuit or diagnose problems in a circuit.
What is the jumper on receptacle?
In home electrical, jumper refers to a wire that transfers electricity from one circuit to another for which it wasn’t originally designed. In the case of jumping from an outlet to a switch, this is typically done by a homeowner who wants to install a new fixture from a nearby outlet on an existing circuit.
What is a circuit jumper?
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.
Can you jumper a receptacle?
If in addition to the electrical cable entering the receptacle box you have an electrical cable or cables leaving the box to feed other receptacles downstream, you’ll need to use jumpers to wire the receptacle correctly.
Is jumper a switch?
Jumpers and DIP switches are two methods commonly used to set hardware options on PCs and peripherals. Although they look different, jumpers and DIP switches perform the same function—allowing you to make or break a single electrical connection, which is used to configure one aspect of a component.
What are switches and jumpers?
Jumpers and switches provide a convenient and reversible way of reconfiguring the circuitry on a printed circuit board. When reconfiguring your system, you may need to change jumper settings on your system board; you may also need to change jumper and/or switch settings on expansion cards or drives.
How do you know if there is 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.
How many outlets can you jump off one?
You Can Use Another Electrical Outlet When:
(Don’t make matters worse by adding yet another outlet to the circuit.) Electrical codes restrict the number of lights or electrical outlets that can be connected to one circuit. Typically, you can have no more than eight lights or electrical outlets on a 15-amp circuit.
How do you jump a switch?
How to Jump a Light Switch
- Open your trip switch box cover. This is where all the circuits in your house connect.
- Unscrew the light switch fitting using a screwdriver.
- Slide the wire out from the terminal labeled “In.” Insert the wire into the terminal labeled “Com.” Tighten the screw.
Where is jumper on motherboard?
Open up the system so you can see the motherboard. Locate the CMOS jumper by referring to the motherboard manual and how to clear the CMOS. In general, the CMOS jumper is three pins located near the battery. In general, CMOS jumper has positions 1–2 and 2–3.
What does it mean to jumper pins?
Jumper pins (points to be connected by the jumper) are arranged in groups called jumper blocks, each group having at least one pair of contact points. An appropriately sized conductive sleeve called a jumper, or more technically, a shunt jumper, is slipped over the pins to complete the circuit.
What is the correct order to attach jumper cables?
Attach the red jumper cables first. Start by clamping one red cable to the positive side of the battery that won’t start. Then attach the other red clamp to the positive side of the working battery. Next, clamp one black cable to the negative side of the working battery.
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 a jumper assembly?
The Concentric Neutral Jumper Assembly is used for bonding purposes on non-jacketed cable. It is usually installed across a portion of cable to be cut, repaired, or spliced. The assembly is left in place until the concentric neutral is spliced.
How do I make an outlet hot all the time?
What you need to do is create a parallel circuit. As always, turn off the circuit breaker for that switch before any changes! For the outlet to be a permanently on, non-switch circuit, you need to bypass the switch. As @JimmyFix-It has said, you need to tie the Red wire and the Black Wires (Live) together.
How do I wire a receptacle from a light outlet but keep it hot when light is off?
In this case, you must change the cable from the switch to the light outlet from a 2-wire to a 3-wire cable. As you can see, connecting a receptacle to the light would see the receptacle only hot when the light switch is on.
How do you stop a light switch from turning off the outlet?
The easiest way to do this is to disconnect the red and black wire from the switch and wire nut them together. Use a blank cover to cover the switch box. This allows you to go back to switched outlets in the future if you want. Make sure there will still be a light controlled by a switch by the door.
How many outlets can you run off a 20 amp breaker?
The answer to the question how many outlets on a 20 amp circuit is ten outlets. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.
How many receptacles can be on a 15 amp breaker?
8 outlets
Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.
Can you put 15 amp receptacle 20 amp circuit?
The amperage of the outlet must never exceed the amperage of the circuit. According to National Electrical Code, only a 15-amp or 20-amp electrical receptacle can be installed to a 20-amp circuit. A 15-amp receptacle may also be installed on a 15-amp circuit.
