They are not required in a breaker box. NEC code requires that you have one 8' ground rod outside under the meter and another 8' ground rod around 6' to either side. Reason is safety.
There are two ground bars in a distribution panel because the feeders to the load can come out of each side of the panel. The bar on the right side of the panel services the feeders that leave the right side of the panel. The bar on the left side of the panel services the feeders that leave the left side of the panel. This saves congestion of ground wires passing from one side of the panel to the other side, which is what would happen if just one ground bar was installed.

How do you ground your meter box to your breaker box?
The grounding is done through the metal nipple that connects out of the back of the meter base and into the back of the breaker panel.
You have 220v wiring 2 hots 1 common from breaker box to pool wiring box Common is wired to equipment ground is that correct?
Correction - 2 hot (2 * 120) = 240 volts common - neutral U R 100% correct PS: 240 motor for pool ? hmmm, learn something everyday The cable from the breaker box to the pool should be a 3 conductor. In that 3 conductor cable there should be a bare ground wire (the ground wire is not included in a cable wire count). The pool ground should be connected to that bare wire, not the white neutral. This bare ground wire is then grounded back at the breaker panel to provide a direct path to trip the breaker in case of a short circuit. Code requires a GFCI ahead of the pool load to detect ground faults. See related links below on GFCI's

How do you upgrade a breaker box?
== == == == === === === === Home owner, big job In the trade this is called a service change. It is a complicated job in as much as you have to know wire sizes, ampacity of wires and proper electrical workmanship. Such a project should be left to a licensed electrical contractor to take out the proper permits and call for proper inspections. By taking this route it will leave you confident that if any mishaps happen to the installation down the road your insurance company will be behind you 100%. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Do you have to break the ground wire at a pull box and bond it to the box?
When you refer to a pull box you have to be talking about a conduit system. In a metallic system, no don't have to ground pull boxes. By the fact that it is a metallic system the conduit and associated boxes are already grounded by the connection to the distribution panel. In a PVC conduit system a ground wire has to be pulled so that the load device has a return ground wire to trip the breaker on a ground fault. Pull boxes in a PVC system don't have to be grounded just the last junction box at the load.
What is the difference between a 100 amp breaker box and a 125 breaker box?
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
When setting up a breaker box how do you determine circuit breaker capacity?
find amphere required

Is a ground fault indicator outlet installed at the breaker box?
There are tow places to put a Ground Fault Circuit Interrupter. There is a GFCI breaker which would be installed in a breaker box and a GFCI outlet that can be installed anywhere. Most GFCI outlets allow you to connect regular outlets to the GFCI and those outlets will also be protected.
How do I connect a wall light switch that has 3 terminals the third being for the ground Which terminal should be connected to power coming from the breaker box?

How do you install lights on garage that now do not have any?
first run electric cable to garage,10-3 with ground is best,you will have to put at least a 30 amp box in garage more if running 220. if just lights and power tools on 110 then you will be fine!! in box connect red wire to proper lug in box and black wire to proper lug. run 14-2 to lghts!! you can use 12-2 also it is a heavier cable!! at house breaker box run the 10-3 cable to its own breaker in box,at least a 20amp breaker!! red and black wires go to breaker and white goes to neutral bar connect ground to ground bar or neutral bar also!! use a double pole breaker in main box.
Where is the headlight circuit breaker?
In the breaker box
In typical home electrical panel installation the main ground wire is connected directly from a ground rod driven into the ground to the?
In North American residential homes, there are 3 wires coming from the utility company, two "hots" and neutral. The two "hot" conductors get connected to the main breaker. The neutral gets connected to the neutral bus bars located along the sides of the breaker box. There is a set screw that is placed in the neutral bar that screws into the distribution panel enclosure thereby bringing the potential of the neutral bars down to zero. The wire from your ground rod is also connected to the neutral bus bar, and thereby it is connected to the neutral from the power company. This is also often bonded to the copper cold water Plumbing in the house if the home is not plumbed in PVC water pipe. White circuit wires are then connected to the neutral bus bars. Also in the distribution panel are ground bus bars. The ground wires from circuit cables are connected to these grounding bars. Do not under any circumstance terminate the white and bare ground wires together. Ground wires to the ground bar and white wires to the neutral bar.
Where do I ground if there is No ground coming out of the box?
The question doesn't say what "the box" refers-to: is it a wall box for a socket outlet or is it for a switch - or is it actually the main circuit breaker panel for the building or apartment?You can add a safety ground wire to any wall box - to connect appliances back to the ground on main breaker panel - only if there is a main grounding wire installed at your main breaker panel.You can't add a safety ground wire to any wall box, to connect appliances back to the main breaker panel, if you don't already have a ground wire installed at your main breaker panel. If that is the case, your wiring must be at least 50 years old. It is time to consult with an electrician...As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How do you ground a 100 amp breaker box that only has two hot wires coming to it?
Sounds very strange and that the electric code isn't being met. If it is main box a ground rod can be driven into earth and a wire grounded between box and ground rod. However, you should have an electrician investigate what is going on since this box is a safety hazard.

What size Aluminum wire is used for ground in breaker box?
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
