A 'hot' terminal is a slang expression for the line terminal of an AC supply. In Europe, for example, a single phase supply to a building has three conductors: line conductor, neutral conductor, and protective (earth) conductor. The line conductor has a potential of 230 V with respect to the neutral; the neutral conductor is at approximately the same potential as the earth conductor. In North America, there are two line conductors, which are at 240 V with respect to each other, and at 120 V with respect to the neutral.

What does common mean in terms of wiring IE hot neutral ground line NO NC?
In terms of hot,neutral,ground, the neutral is classed as the common. In regards to a switch which has a NO, NC, C. This is classed as a C form switch. It has a common terminal, a normally open terminal and a normally closed terminal. Depending on the position of the switch handle the circuit can be either open or closed.
Would a relay be wired differently for a sourcing and sinking output module?
Yes. For sourcing output, the relay coil is wired to (common or ground) and the output terminal. For sinking output, the relay is wired to (voltage supply or hot) and the output terminal.
What is the third terminal on electric equipment?
The third terminal connects to earth ground.
If the excitation of generator changes what happens to the terminal voltage?
By Decreasing the excitation voltage the terminal voltage will decrease and similarly by increasing the excitation voltages the terminal voltage will also increases.
What are the M L C V terminals of a watt meter?
The M terminal connects to the power supply. The L terminal connects to the load. The C terminal is shorted to the M terminal. The V terminal connects to the systems neutral.
Wiring off road lights?
I would wire them using a common relay and a ground switched circuit i.e. Terminal #30 Hot Terminal #87 Load Terminal #85 Hot Terminal #86 Switched to Ground
What is screw is for the hot wire?
The gold terminal
Why would the earth terminal get hot when the car is off?
This depends what Earth Terminal you mean The one on the top of the battery, You may have a bad battery. Disconect it and come back in 24 hours and see if it is dead. Not dead means that there is a short in the electrical system and this terminal needs cleaning. If the battery is dead the battery is bad, replace it. If this is another terminal and gets hot and stays hot it means there is a large draw on the system and this terminal is dirty and requires cleaning. The hot terminal is allways the highest resistance in the system. Good Luck
Could a bad key switch cause the positive battery terminal to get hot?
No, the battery terminal should be able to handle as much electrical current as the vehicle should ever use, WITHOUT heating up. Clean or replace any battery terminal that is getting hot.
Why is your battery terminal hot?
some accessories draw juice all the time, but most of those will be minimal and of no consequence. Generally, if you find a hot terminal on your battery when you try to connect, it indicates that you have a short somewhere.
Why alternator terminal wire is getting red hot?
because you forgot to put lube on it
What wire is positive when changing the speakers in a 2002 Saturn Vue?
Just use an old small battery lying around.With 2 wires,connect to speaker terminals.Now TOUCH Breify the other ends of the wires to that little battery. But watch the speaker.If you have hot on hot the speaker cone will push outward. If you have hot wire on negative speaker terminal the speaker cone will want to suck in. Sometimes the speaker will have one big terminal and a small terminal.The larger terminal is the hot side of the speaker.
What does common mean on a light switch?
On a single pole single throw there is no common terminal. On a single pole double throw it is the terminal that is common to both the top and bottom terminals. The "hot" wire is connected to the common terminal so that when the switch is in the up position that terminal becomes energized and there will be no no voltage on the bottom terminal. When the switch is in the down position the bottom terminal becomes energized and there will be no voltage on the top terminal. In relays thisis known as a C form configuration.
What does common mean in terms of wiring IE hot neutral ground line NO NC?
In terms of hot,neutral,ground, the neutral is classed as the common. In regards to a switch which has a NO, NC, C. This is classed as a C form switch. It has a common terminal, a normally open terminal and a normally closed terminal. Depending on the position of the switch handle the circuit can be either open or closed.
Positive car battery terminal gets too hot to touch is that normal?
No, Remove the terminal and clean with wirebrush until both the clamp and battery post are shiny.Re-install.The heating problem should be eliminated.
How do you wire a Nema L5-30 plug?
An L5-30P is a two pole three wire grounding 30 amp, 125 volt plug . The neutral wire is connected to the W terminal, the ground wire to the G terminal and the hot wire to the only terminal that is left. The small blade/slot is neutral (white), the larger blade/slot is hot (black) and the notched blade/slot is ground (green).
What is hot in nc no com in term of electrical wiring?
The hot wire is usually connected to the common terminal of a NO, NC device. This type of contact arrangement is known as a "C "form arrangement.
