Many panels do not have a ground buss. Look for a set of screws mounted directly on the back of the panel adjacent to the breaker outputs. These are to be used for the ground wires. Square D panels are one of many that use this configuration.

How do you wire a 220v connection into the main panel?
I assume you mean you are wiring a 220 volt circuit. You will install a 220 volt double pole breaker of the correct size for the circuit. An example would be for an electric dryer that requires a 30 amp double pole breaker wired with 10/3 wire. You connect the Red & Black wires to the breaker. One on each screw. You now connect the White wire to the neutral bus bar in the service panel. Then connect the bare copper ground wire to the ground bus bar in the service panel. At the dryer outlet connect the black & red to the hot screws, white to the neutral, and ground to ground. They will be labeled on the back of the outlet.
Can you pigtail grounds in a panel in order to prevent double lugging on the neutral bus.?
The ground wires should not be terminated on the neutral bus. They should be terminated on to the ground bus which should be located on the back wall of the distribution panel. The wires don't have to be pigtailed when inserted into the ground bus. More that one wire can go under the terminal screws if you are running out of room. Shut the panel off and remove any ground wires that are now under the neutral bus terminals and move them to the ground bus. Some panels use a lug for a ground bus. All ground wires into the lug and tighten. In a ground fault condition it is the ground wires that are connected to the ground potential that trip the breaker, not ground wires connected to neutrals. Be safe.
Can neutral and bare copper wires be under the same screw on a bus bare in a single family home electrical panel?
No, ground wires should not be terminated on the neutral bus. They should be terminated on to the ground bus which should be located on the back wall of the distribution panel. More that one wire can go under the terminal screws if you are running out of room. Shut the panel off and remove any ground wires that are now under the neutral bus terminals and move them to the ground bus. Some panels use a lug for a ground bus.

How do you connect the wires for a 200 amp sub panel to a 200 amp main panel?
Assuming garage is detached less than 80 ft away. You need a 60 AMP double pole breaker for the 200 AMP house panel, and need to have two spare slots. Additionally you should have conduit in running in ground, and have #4/3 W/ground Stranded cable running to the sub panel. This setup will allow for 110V's and a 220V circuit. Connect the two hots, Red/Black to the Breaker on your servicing the panel. Connect the neutral (White) to the Neutral bus bar along with the Ground wire. Sub panel on detached Garage. Attach the White neutral wire to the Neutral ground bar. Attach the ground to the ground bar on the Sub panel. Pull the permits and have it inspected! If your house has the wires from the meter going straight into your panel box then you tie the neutral and ground to the same busbar. However; If you havve a disconnect on the outside of your house then you must separate the neutral andground inside the 200 amp panel box. This is usually prevalent on a mobile home or any time the pnel box you are using is fed from another panel or disconnect.
Why do electric appliances have green wire?
The green wire is designated as a ground wire. This wire in a feeder cable is bare copper and connects to the distribution panel's ground bus and at the load it is connected to the frame ground of the equipment. The UK uses the same colour for the grounding or earthing but it also has a yellow tracer on the green colouration.
Are neutrial and ground wires to be separated in electric main box?
Yes, if possible, connect the grounds to the ground bus bar and the neutrals to the other side on the neutral bus bar. This is just in case you ever install a sub panel. It is not a violation of the NEC code to connect them to the same bus bar but IMO it is unprofessional and can cause problems later on.
Typical home electrical panel installation the main ground wire is connected directly from a ground rod driven into the ground to the?
Ground bus in the panel.

What network uses a central cable to which all network devices connect?
bus network
How is a 208 volt 3 phase electrical sub-panel wired?
Mark the phases red (phase) black (phase) and blue (phase) along with a white (neutral) and a ground (wire size depends on the main breaker amperage) the phases attach to the main breaker unless it is a breakerless panel attach the phases to the lugs on the bus bars top or bottom then connect the neutral to the neutral bus and the ground to the panel

Where bus topology used?
Bus topology is used on a LAN, or a Local Area Network. It is the cable to which the nodes connect, and it is also known as a backbone.
What is the difference between ITE and FPE circuit breaker?
The connection blades and how they connect into the distribution panel's bus.
Do the grounding conductors and bonding conductors ever connect to a common point?
Answer for USA, Canada and countries running a 60 Hertz supply service.The grounding electrode conductor is brought into the main disconnect section of the distribution panel and a connection is made to the neutral block. The terminations in the panel at this point are two incoming "hots" to the main breaker and a neutral wire to the neutral terminal block. In the neutral termination block there is a ground screw that screws through to the distribution panels metal enclosure, there by making the metal enclosure the same potential as the ground plate or rods and the neutral wire that comes in from the street. The grounded circuit conductors of the wiring system are terminated on a separate ground buss that is located in the circuit breaker section of the panel. This buss is bolted directly to the rear of the distribution panel's metal enclosure in the circuit breaker section of the distribution panel. This ground buss is at the same potential as the ground electrode conductor above because of the grounding screw that connects the neutral block to the metal enclosure. Code requires when wiring sub panels within the same building that the neutral block screw be taken out of the circuit and a separate ground wire be run directly from the main distribution panel. This is to prevent any short circuit currents from the sub panel traveling back on the sub panel feeder's neutral wire.In house wiring you have earth ground connect to the ground bus in the main electric panel. Your neutral bus is "bonded" to the Ground bus only at the main panel. When you run branch panels you do not connect neutral to ground in these branch panels, only the main panel. There is typically a screw in an electric panel where the bonding occurs.

Where do you ground on 100 amp panel?
A typical panel has three large wires entering the main panel from the electric meter and a bare ground wire. Two of the large wires are hot and go to the busses where the breakers are mounted. The third wire is common and is connected to one or more common bus locations. It will usually be silver in color with a screw on top to connect white wires from branch circuits. The ground is the metal of the panel itself and there will be one or more ground busses usually copper colored that are connected to the metal of the panel by screws there by "bonding" these ground busses to the metal of the panel. You should also see a copper wire coming from a ground rod connected to the metal of the panel. At the main panel you need to bond the common to the ground. There is usually a screw that allows this bonding to occur. If you have subpanels ground and common are NOT connected at the subpanels.
