How can you connect a system working with 60Hz 1 Hot wire 1 neutral wire and a ground wire to my utility system that works with 60Hz two hot wires and a neutral wire?

Your 2-wire system is actually connected to one "side" of the 3-wire system.
In your utility's 3-wire system you have 2 hot wires that are attached to each end of a tranformer winding and the neutral is attached in the middle and grounded. Typically in the US this gives you 240v (or something similar) between hot leads and 120v from each hot lead to neutral or ground.

How do I rewire an ungrounded plug?
If there is no ground wire connect the ground wire to the neutral wire.
What can happen if a utility-sized electrical generator has an ungrounded neutral?
What you need to define is the statement "utility- sized electrical generator". It depends on what the generators output is used for as to the way it is internally wired. In some configurations there is no neutral to ground as in a Delta configuration.If the generator is configured for a Wye output and the neutral centre tap is not grounded there will be a floating voltage between the generator and the utility system ground. It is for this reason that the generator's neutral point is grounded to bring the floating voltage down to zero volts to ground.
Does all romex have a ground wire?
Some older wire does not have a ground. All you can do in that case is use a jumper wire to connect the ground to the neutral.
How do you hook up the distribution panel box with red white black and ground wires?
Without more information that appears to be a 240 volt circuit. Red & black would connect to the 240 volt breaker, white connects to the neutral bar, and ground conductor from the ground rods or ground plate connects to the neutral bar. Make sure that the bonding screw is in the neutral bar and it is screwed through to bond the distribution panel enclosure to the neutral bar.
Why is it that when you touch the neutral in a box that is not connect to the panel cause the test light to come when touching the power wire?
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
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.

How do you wire a wire to a wire?
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
Why do you isolate the neutral?
If you are working with a sub panel, there are a few reasons to isolate the neutral. Firstly, currents will then return to the main panel and service ground.
Is it OK illegal or dangerous to connect the neutral to ground to make the circuit work?
Connecting the neutral and ground wires in a circuit is dangerous and against electrical code because it can create a hazardous condition known as a ground fault. This can lead to electric shock, fires, and damage to equipment. It is important to keep the neutral and ground wires separate to ensure the safety and integrity of the electrical system.
Can you connect the ground and neutral coming out of a cooktop to the ground of a nm8 2 wire?
No, the ground and neutral wires should not be connected together at the cooktop. The ground wire from the cooktop should be connected to the ground wire in the NM-B cable, and the neutral wire from the cooktop should be connected to the neutral wire in the NM-B cable. It is important to follow proper wiring practices to ensure safety and compliance with electrical codes.
Can you connect a ground to a neutral bar?
In any distribution panel there are individual bars for each termination. The ground buss is in direct contact with the metal enclosure. The neutral is isolated from the metal enclosure. The only place where the two come into contact with each other is where a bonding screw protrudes through the neutral bar and into the metal enclosure.
Can you turn on power to a house without a ground wire?
No. If the service is missing a ground wire the electrical inspector will not pass the installation. With out the inspectors approval the utility company will not connect the house and turn the power on.
Does the ground wire from a 240 volt tankless water heater connect to the common wire?
Any ground wire has to be connected to an independent ground wire that returns directly to the distribution panel and not to the neutral of the circuit.
Define earth voltage and neutral voltage?
As the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Current carried on a grounding conductor can result in objectionable or dangerous voltages appearing on equipment enclosures, so the installation of grounding conductors and neutral conductors is carefully defined in electrical regulations. Where a neutral conductor is used also to connect equipment enclosures to earth, care must be taken that the neutral conductor never rises to a high voltage with respect to local ground.
