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.

∙ 13y agoThe bare wire should be connected to the ground bus in the subpanel for an older clothes dryer with a three-wire cord. This is to ensure proper grounding and safety for the appliance operation.
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.
No, you should not connect the neutral wire of the 120V outlet to the middle wire of the 240V service. The neutral wire should be connected to the neutral bus bar of the electrical panel. Additionally, the ground wire should be connected to the grounding bus bar of the panel, and it should not be "grabbed" from another source. Proper grounding is essential for safety and to prevent electrical hazards.
Black & Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.
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.
No, it is not possible to connect a 3-phase 440 V system without a neutral line to a machine that requires a 3-phase 4-wire connection with a neutral line. The neutral line must be present in both systems for proper operation and safety. Trying to connect them without the neutral line could cause damage to the machine and pose a safety hazard.

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.

No, because cotton is relatively neutral
Connect to the circuit neutral wire which should also be white.

A phase leg connects to the neutral through the connected load.
