What wire is used for jumper wires?
Most important thing to remember is you must use solid-core wire, ideally 22 American Wire Gauge (AWG). Make sure you don’t nick or cut the wire, because that could weaken it. Cut the other side to length, remember you’ll need a little extra so that you can strip the other end too!
Can you use any wire for jumper wire?
Look for 20- or 22-gauge wire. In North America, the gauge is often labeled AWG (for American wire gauge). You also need a wire cutter and a wire stripper, or one tool that does both jobs, as well as needle-nose pliers.
What are jumper wires made of?
SHOWA jumper wire (NSL: New Showa Lead) is a lead-free tin-plated annealed copper wire. Tin plating is tin: 99.2%, copper: 0.8%. In general, it is said that hot plating is difficult to control the plating thickness compared with electroplating, but we control the plating thickness by the original processing method.
Do I need a jumper wire on my thermostat?
If your HVAC system has both heating and cooling functions, you’ll need to connect both the Rc and Rh terminals with a red wire. Because many thermostats come with a pre-installed thermostat jumper wire that connects these terminals, you only need one red wire, which could be the thermostat Rc wire or the Rh wire.
What is a jumper wire used for?
Jumper wires are simply wires that have connector pins at each end, allowing them to be used to connect two points to each other without soldering. Jumper wires are typically used with breadboards and other prototyping tools in order to make it easy to change a circuit as needed. Fairly simple.

Why is there a jumper between R and RC?
Effectively there isn’t a second RH wire, although there is an RH terminal. However, the heating still needs to be controlled, so a wire known as a jumper is connected between the RC and the RH terminals so that power gets to the heating control part of the thermostat. This wire is also known as the RH wire.
When do you add a PCB jumper to a circuit?
The second is when a PCB jumper is added during assembly but is considered a circuit component. It generally takes the form of a small copper wire or flat wire that is usually soldered using the same automated methods as for other board components. In the old days, jumpers were often made up by hand.
Where do you place a jumper wire on a circuit board?
Form the wire as needed and place the wire in position depending on the termination style. Center the wire on the component lead or pad, do not overhang sides. If the wire is soldered to a pin, terminal or component lead, wrap the wire a minimum of 90 degrees.
How big should a printed circuit board jumper be?
The device is formed so it loops up about 0.05 in. above the circuit board. Thus is has a low profile but also provides clearance above the board so it needn’t be insulated. It can be either 0.08 or 0.12-in. long and 0.05 or 0.062-in. wide respectively.
What should I do if my jumper wire passes over a pad?
If a jumper wires passes over an unused land or pad sufficient slack should be provided so that the jumper wire can be moved out of the way should a component need to be added. Jumper wires should not pass over pads or vias used as test points.
