What is the definition of the connection between the grounded circuit and the equipment grounding conductor at the service?
2008 NEC - Article 100 Definitions - Bonding Jumper, Main Main Bonding Jumper is the answer.
What size copper main bonding jumper is required based on the service entrance conductors being rated at 250 kcmil thwn-thnn copper?
A size 3/0 AWG copper main bonding jumper is typically required for service entrance conductors rated at 250 kcmil copper. This is based on NEC requirements for sizing the main bonding jumper to be at least 1/10th the circular mil area of the largest service entrance conductor.
A jumperless motherboard is likely to have one jumper Which jumper is it?
A bios or cmos jumper
What is jumper parking?
"Jumper Parking" is when you have a Jumper hanging on one pin for safe keeping, rather than using it to turn a Jumper Setting on.
How do you knit Ravenclaw jumper?
Find directions for a jumper and knit a blue jumper. If you are skills you could knit the Ravenclaw symbol onto the jumper otherwise you can buy the badges and sew them onto the jumper.
What size bonding jumper for 200 amp service panel?
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.
Can the ground wire pass through the same conduit as feed wires from panel to meter?
If you are asking simply a technical question the answer is no, because ground wires do not exist from the panel to the meter. My advice to you is this: If you have an inspector telling you to do something a certain way, do it his way unless in your professional opinion you believe to do so would be unsafe. What is properly called a ground wire, or what the NEC calls a groundING conductor (as opposed to the groundED conductor) does not run from the meter to the panel. From the meter to the panel you will have the groundED conductor, which is the neutral, and possibly a bonding jumper. The bonding jumper is probably what you are referring to as the ground wire. The code requires that all components of a service be bonded together. The components for a common home are just the meter and panel, but may also include a separate disconnect, junction box, or CT box. Typically the bonding jumper is run in the same raceways as the service conductors, but since the NEC prohibits any other conductors in a raceway that carries service conductors some jurisdictions do not allow the jumper to be inside the raceway or conduit. Technically the bonding jumper is not a conductor even if it is a wire. Grounding and Bonding are 2 of the largest sections of the NEC and the most misunderstood. To the untrained eye they look alike as they both often use green or bare wires to accomplish their tasks. Understanding the difference, the proper difference, between grounding and bonding is a step in the right direction but many professional electricians use the terms improperly and cannot make a reasonable explanation of what is the purpose for each. I invite answers from other electricians as I'm sure my explanation is much more complicated than the questioner wanted or needed.
How does a trampoline work?
Applied physics! The jumper uses muscles to generate energy. This energy is used to overcome gravity, and the when gravity returns the jumper to the tramp, the tramp "catches" the jumper. In catching the jumper, the tramp stores the jumper's energy in its springs, and then returns it to the jumper. Simple and easy.
