Both the earth wire and the neutral originate from the star point of the transformer. The neutral is used to complete the circuit with one phase, while the earth wire is used to conduct any current from the exposed metal body of the equipment to earth and to the star point of the transformer. This is done to protect people and animals in the event of accidental contact with electricity.
Electricity will always follow the route of least resistance. Copper/aluminium has a much lower resistance than the human body. In the event of the live wire making contact with the earthed metal body of the equipment, the earth wire will conduct the electricity to the earth mass. Without an earth wire connected to complete the route of least resistance to earth, the human body will conduct the full load current to earth if you should touch the live metal of faulty equipment. This could result in electrocution

Equipment ground-ING conductors (commonly called "ground wire" or "the ground" and is usually green or bare) and groundED conductors (commonly called the "neutral" and is usually white or gray) are required to be bonded together at the main service panel. It is common practice to put both ground and neutral conductors on the same buss bar in the main service panel which effectively bonds them together. Then, if the incoming neutral and outgoing grounding electrode conductor (that's the conductor that is connected to building ground, or ground rods, and/or water pipe ground) are connected to the same buss then everything is bonded together and grounded as required.
Ground wires and neutrals should not share a buss bar and should be isolated from each other in any sub-panel.
Ground wires and neutral wires are connected to the same bus bar in a main electrical panel to provide a safe path for current in the event of a fault. The neutral wire carries the current back to the source, while the ground wire is designed to carry any fault currents safely to the ground. Keeping them separate helps to ensure proper functioning of the electrical system and reduce the risk of electrical hazards.

Can groundwire be together with neutral wire at the dyer?
No, ground wires and neutral wires should not be connected together at the dryer. The ground wire provides a safe path for electricity to be directed away in the event of a fault, while the neutral wire carries the return current to the power source. It is important to keep them separate to ensure proper grounding and prevent electrical hazards.
Do I need two ground wires -one for each socket- if I split an outlet?
No, you do not need two ground wires if you split an outlet. The ground wire can be shared between the two new outlets, as long as it is connected properly to both of them. Make sure the ground wire is securely connected to both outlets to ensure proper grounding for safety.
How a 240 V GFCI breaker works without a neutral ran to the equipment?
A 240V GFCI breaker monitors the difference in current between the hot wires, providing ground-fault protection without needing a neutral wire. It compares the current on both hot wires and trips if an imbalance is detected, indicating a ground fault. This system does not rely on a neutral wire to detect faults and protect against electrical shocks.
Would the black wire be line 1 on 240V line in?
No, the black wire is typically associated with line 2 in a 240V line. In a 240V circuit, there are two hot wires - line 1 (black) and line 2 (red), as well as a ground wire and sometimes a neutral wire.
Why Hot and neutral are both hot?
The hot wire carries current to the appliance, while the neutral wire returns the current back to the power source. Both wires are considered "hot" because they can carry electric current, but the hot wire is at a higher voltage compared to the neutral wire. It is important to keep them separate to maintain the circuit's intended flow of electricity and prevent electrical hazards.
Can 1 0 wire be used for both hot wires and ground in a service entrance?
Yes 1/0 wire can be used for both ungrounded( hot wires) and the grounded conductor (neutral).
Why not hook ground to neutral since they are hooked on same spot in breaker box why not in outlet box.?
The "hot" wire and the neutral wire both carry current (the same amount, in fact) when a load is connected to complete the circuit. The ground wire never carries current except when a fault-to-ground situation occurs. Yes, neutral and ground wires should both be at ground potential, but NO they should not be connected at the outlet.
Can groundwire be together with neutral wire at the dyer?
No, ground wires and neutral wires should not be connected together at the dryer. The ground wire provides a safe path for electricity to be directed away in the event of a fault, while the neutral wire carries the return current to the power source. It is important to keep them separate to ensure proper grounding and prevent electrical hazards.

My light fixture has writing on one wire but not the other?
If both wires are black then the one with the writing is the neutral wire. If the two wires are black and white then the white one is the neutral.
Would the black wire be line 1 on 240V line in?
No, the black wire is typically associated with line 2 in a 240V line. In a 240V circuit, there are two hot wires - line 1 (black) and line 2 (red), as well as a ground wire and sometimes a neutral wire.

The two wires in my stock 56 Mercury radio are both black but one is larger than the other so which wire is the hot lead and which is the ground?
Chassis is ground (neutral) in a car. The two hot wires are for the radio and the light. Connect the smaller wire to the dash light circuit and the larger wire to the accessory circuit.
If there are two black and one white wire in ceiling light do I need to use both black for the switch to work?
If there are two black wires, it's possible that it was wired for a ceiling fan and that one of the wires is for the fan part while the other is for the light part. If so, one of the black wires may be switched while the other is always "on." Normally black is "hot" and white is "neutral" (NOT ground... ground is usually green).
How do you wire a 220v three prong to a 220v four prong?
You'll need to contact an electrician who will pull a new wire for you. If you only have 2 wires on the 240 line, you don't have a neutral or a ground; both of which are essential for a modern electric range.
Do you need a neutral wire to a switch when they both are hot wires?
It depends on the circuit used, but usually, yes.
