What else can I help you with?
Which wire will be connect at NO or NC contact?
NO stands for Normally Open and NC is Normally Closed. It references a switching application. It is the base state of the switch. So if the load is connected to the NC terminal it will usually be energized and when the switching device is activated the circuit will open and the load will be de-energized. The NO terminal would have the load de-energized until the switch was activated and then it would be energized.
Difference between on load and off load isolator?
In electrical system load means circuit carrying current . Isolator is device which make on ( Connect ) and off ( Disconnect ) of circuit from supply. When load is ON means carrying current and required to disconnect from supply , than is called on load isolation.Here required on load isolator. When load is OFF means not carrying current and required to disconnect from supply , than is called off load isolation.Here required off load isolator. On load isolators design is more precise than off load isolator because while isolating load during ON states create heavy sparking and transient voltage spikes.
What distinguishes a switching power supply from other power supplies?
Normal power supplies are on all the time while switching type are on and off periodically which results in precise control and improved efficiency.
What are cut-off and saturation points in a dc load line?
The cut-off point is the exact point where the load line crosses with the vector axis. The saturation point is the point where the load line intersects with the collector current axis.
How does a switching on and off can be done in a sequence of loght for example in a miniature lighting circuit we put in a marriage function?
switching on the tourch for example is when as you switch it on it will move the switch connecting it to a circuit that lights up the bulb and when you switch the switch off the switch will move breaking the circuit
What are the positions of the primary switching center load interrupter switch?
The load interrupter switch positions in a primary switching center are typically "closed" when the switch is engaged, allowing electricity to flow, and "open" when the switch is disengaged, cutting off the electricity flow. Some load interrupter switches may also have an "earth" position for grounding purposes.
Why should you switch off a load?
You should switch off loads to save electricity and money for the electric bills.
The load interrupter switches of the primary switching center can be operated when the circuit is energized?
true
The load interrupters of the primary switching center provide internal grounding for?
all three of the phases
Would you put an electric switch on a neutral wire?
NO! Never switch the neutral, just switch the hot. You would be creating a shock hazard. Switching neutral leaves live voltage at the device even when it appears off. Someone touching the hot and grounded would get a shock.
My iPhone wont finish on the checking for update screen what do i do?
Do the 'old favourite' of switching the phone off and on again. Switching the phone off - severs the connection to the internet.
When are they switching off the hadron collide?
Not for many years.
What is cold booting?
it is switching when the p c is off
What is on-load tap-changing?
On-load tap-changing is done in electric power supply systems to maintain the supply voltage to customers within limits. Tapping is done by switching extra turns in or out, usually on the high-voltage winding of a transformer. The switching is done by a make-before-break switch to avoid excessive sparking in the transformer, and this enables the switching to be done without interrupting the supply.

When was Take a Load Off created?
Take a Load Off was created in 2010-06.
What does the idiom take a load off means?
The image is of you "taking a load off" of your feet, which are holding you up. If you take a load off your feet, you'd sit down. This is most commonly used as an invitation to sit, as in "Come on in, take a load off."
