Can neutral and bare copper wires be under the same screw on a bus bare in a single family home electrical panel?
Ahi5518074
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. 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.

Why is neutral line needed in home electricity?
A fuse is NOT fitted in the neutral phase of single phase domestic power supply. The fuse is fitted in the LINE (also mistakenly called Live). If you have checked and found that the fuse is in the neutral, something is wrongly wired.
Where is the single electron in an electrically neutral atom of hydrogen located?
The single electron in a neutral hydrogen atom resides in the 1s orbital.
Where does the neutral wire go on a single pole switch?
Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole switch.
Is copper made up more than one element?
No. Copper is a single element.

Why are there are many insulated copper wires instead of a single long wire in electrical appliances?
Because copper can connect one thing to another so there are multiple wires to connect multiple things
In science what is neutral?
Neutral-not moving;on a single position
Why does a free atom have no electrical charge?
A free atom has no electrical charge because it has an equal number of protons and electrons. Each proton has a single positive charge, and each electron has a single negative charge. These balance each other and the result is a net neutral atom (or no net charge).
Is 1 GbE Ethernet really Ethernet Explain?
Yes; Ethernet is really not a single technology, but a family of technologies. Details vary, for example between fiber optic and copper cable; but it is still considered "Ethernet".Yes; Ethernet is really not a single technology, but a family of technologies.

How decide Electrical Main Feeder size?
It is based on the amperage of the service panel in a single phase home panel useing copper wire use. 100 amp use AWG # 3 copper 200 amp use AWG # 3/0 copper

Neutral is a return path.
