On a older clothes dryer that has a three-wire cord where does the bare wire connect in the subpanel - on the neutral buss or the ground?

WARNING
Do not use 2 conductor with ground cable to feed a 3 prong 120/240V dryer outlet. The outlet is ungrounded, and the third conductor is neutral not ground. Your ground wire must be sheathed by code. You cannot use the bare neutral conductor as ground.Another answer
You should not connect a three wire circuit for a dryer to a sub-panel, it should go all the way back to the main panel. The code never allowed a three wire circuit with a bare neutral to go to a sub-panel. By connecting the three wire cable to the sub-panel you take the chance of energizing the enclosure for the sub-panel if something were to happen to the grounding conductor from the main panel. Four wire circuits were required for dryers anytime they originated from a sub-panel, now the code requires all dryer circuits to be four wire: two hots, neutral and grounding conductor.

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.

Where is the only place the neutral and ground wires can be on the same buss bar?
The main electric panel is where neutral is bonded to ground. There is usually a screw or strap that connects the two so the same type panel could be used as a subpanel and have the neutral and ground unbonded in subpanel.
When wiring a 120V outlet from a 240V 3 wire service can you just connect the neutral white to the middle wire of the 240 and grab a ground from another source?
The 240 transformer that delivers power to your home has a "center tap", which gives 120 VAC to each side from the center and 240 from "hot" to "hot". It sounds like you're describing it correctly. Use the center tap and one of the hot lines to give you 120VAC, and there should be a ground bar inside the breaker panel that you would use to provide ground to the plug. The neutral and ground may or may not come from the same "source", depending on what you're trying to do. If you run a 240 feeder to a subpanel in a separate building you run two hots and a neutral and you put in a separate grounding rod to connect to the ISOLATED ground in the subpanel. The neutral and ground are not allowed to be connected together in that configuration. If you're running a 120 circuit instead, you run hot, neutral and ground together from the main panel to the subpanel.
How do you put on a four prong outlet on a roper electric dryer?
Black & Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.
In a home circuit are the neutral and ground bare wires always connected?
They are always connected, but at one and only one place, the service entrance. For instance, if you are adding a subpanel to an existing house, the subpanel will probably come with the ground bus and the neutral bus tied together with a special bonding screw. To be legal, you must remove this screw, isolating the neutral from ground. The house's main panel still has the bonding screw or jumper in place, and remains the only place the connection is made.
How do you wire into the main power supply when installing a 50 amp electrical box for a small shop?
Ideally you need two open breaker locations adjacent to each other. Install a 2-pole breaker to supply 120/240 volts. Rating of breaker should 50 A to subpanel. Do not bond neutral and ground in the subpanel.

Do you need a grounding rod at a subpanel on a detached building?
Yes. The panel must be grounded with its own grounding rod. The ground will not be provided with the feeders to the panel, these will only contain your phase wires and neutral. Also make sure that any subpanel installed does not have the neutral bonded to ground. This should only be done at the main panel where the electrical utility service is connected.

What happen when neutral connect to live?
short circuit
Do cotton clothes get more charged than nylon clothes?
No, because cotton is relatively neutral
Where do you connect the white wire from the shunt breaker?
Connect to the circuit neutral wire which should also be white.
How does a phase leg connect to a neutral in an electrical circuit?
A phase leg connects to the neutral through the connected load.
Where do you connect the speaker ground wire?
remember the + side of the speaker basically means neutral, in all electric projects the - is always the live line, so if + means neutral that basically means that ground would also be neutral, speakers dont need ground, so if u wish connect + with neutral on the speaker.
