Copper laminated flexible jumpers are manufactured by stacking high conductivity, electrolytic grade copper foils and then pressure welded. The process is designed in such a way that it enhances the current carrying capacity with almost nil, millivolt drop across the connector. Copper jumpers carry the same current as that of Busbars as they have a constant cross section over the whole length giving a nil millivolt drop. So these kind of jumpers are ideal substitutes for solid busbars. Applications of these jumpers are wide, catering to the many industries like Power Plants, Transformers switchgear's, electricity boards, chemical plants, locomotives, etc.
Flexible jumpers are an excellent and cost effective interconnection for applications requiring flexibility.

On Receiver: Open receiver There is a Jumper called Learn Short for 1 second. (Use jumper or Screwdriver) Remove jumper/screwdriver led on receiver switches on. On Remote/Transmitter: Press the button required for that receiver. Led goes off on receiver after a few seconds Push same button selected on remote again. The led will flash on receiver. Procedure complete.

2008 NEC - Article 100 Definitions - Bonding Jumper, Main Main Bonding Jumper is the answer.
Copper 99%
Copper
Based on NEC 250.66- #2 copper or 1/0 aluminum.
How much heat energy is required to raise the temperature of 0.358 of copper from 23.0 to 60.0 ? The specific heat of copper is 0.0920
Many Fords of that vintage required that a jumper be placed on a socket near the distributor. Without the jumper in place it's not possible to change the timing of the engine. Install the jumper, set the timing with a timing light THEN remove the jumper and it should stay. You'll need to get a reference manual to identify the jumper location and to determine the proper timing advance settings.
A threaded copper fitting on the copper side, male or female, and the galvanized is screwed into it.
There is no bonding jumper wire required on a 200 amp service panel. The meter stack is metallic and is continuous from the mast head down to the distribution panel. If you are talking about the ground wire for a 200 amp panel it requires a #6 bare copper conductor that connects the grounding rod or plate to the neutral point in the distribution panel. Assuming the answer above is an example of a service, where the meter is stacked above the first service disconnect and is mated to this panel by a threaded hub. However if your meter were to be mounted beside your first service disconnect and a metal nipple with lock nuts were used for raceway. You would be required to have a bonding jumper on that nipple sized according to NEC Table 250.122. So for 200 amp that would be #6 copper or #4 aluminum.
I don't know what the NEC - OR 2011 is. Is that a code book for the state of Oregon? The NEC does not allow using a gas pipe as a grounding electrode. You run the risk of heating the gas to explosive temperatures.
