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.
What else can I help you with?
Can groundwire be together with neutral wire at the dyer?
Ground and neutral should only be connected at the main electric panel to prevent parallel neutral currents. If it is a new installation, you must provide four wires (two hots, 1 neutral, & 1 ground) and connect to the four separate (appropriate) places on the dryer. If it is an existing installation and it only has three wires (two hots and a neutral) connect the neutral to both the neutral and ground connection of the dryer (the National Electrical Code allows this exception for older homes). Call a qualified electrician to do any electrical work.
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.
Why Hot and neutral are both hot?
You'll have to explain your problem better.If HOT black and Neutral White in your house wiring are both hot then Neutral is NOT bounded to ground in main panel and neutral could be floating. There should be no voltage between Neutral and Ground (Bare wire in panel). By code if there are multiple panels Ground is only bonded to Neutral in th emain entry panel. I have seen cases where this bonding was not done. At your main panel check voltage between neutral and ground. It should be zero.
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.
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.
How can I wire a bathroom fan and light to operate on the same switch?
To wire a bathroom fan and light to operate on the same switch, you will need to connect the hot wires from both the fan and light to the hot wire coming from the switch. Then, connect the neutral wires from both the fan and light to the neutral wire coming from the switch. Finally, connect the ground wires from both the fan and light to the ground wire coming from the switch. This will allow you to control both the fan and light with a single switch.
Can you explain how the neutral and ground wires are connected on the same bus bar in an electrical panel?
In an electrical panel, the neutral and ground wires are connected to the same bus bar to provide a path for electricity to flow back to the source and to ground any excess electricity for safety. The neutral wire carries current back to the source, while the ground wire is a safety measure to prevent electric shock. Connecting them to the same bus bar ensures that both wires have a direct path to return electricity safely.

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.

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).
