It is because that Isolators does not have any arc quenching medium with it, Whenever you make or break any contacts on load it produces arc which is to be quenched or it may harm man & material. Therefore it is not advisable to operate Isolators at on load condition.

What is lock out relay function why it is needed?
Lock out Relay is the Master Trip relay( It is a latch relay once operated we have to reset it by manual) Which is used for Generator protection,Transformer protection,Turbine protection (Fixed in indoor Panel, Standard manufacturer only making those relays) if it operated because of any fault in above the after clearing all the fault we have to reset it by hand(normally available 110Volts or 220Volts DC).
What is The unit of a computer that does the actual computing or processing?
The actual computing is done on a Random Access Memory (RAM) chips under the control of a ROM (Read-only memory) chip. Collectively these are described as the Central Processing Unit (CPU)
How many directions does current flow through a diode?
A diode allows only current flow in one direction under normal operation. Exceed the operating voltage and it can break down allowing bi-directional flow.
How do you wire two lighting circuits through a time clock?
If you mean two separate circuits from different breakers, you will need a 2-pole time clock. The circuits will need to be kept completely separate, including neutrals. Remember that a time clock is just a switch operated by a timer and you only switch the hot wires. The clock will be operated by one of the circuits. For this you will need the neutral of that circuit connected to the neutral contact of the clock. This is all rather simple if you can follow the wiring diagram provided with the clock. I doubt you can find a 2-pole clock at the local hardware or home improvement store. You may have to go to an electrical supplier. I say this is simple and for an electrician it is. If you get the clock you need and it doesn't make sense to you in a minute or two you should not attempt to do this yourself. Crossing the hot wires or connecting the wrong neutrals to each other can create very unsafe conditions.
I am adding a 30 amp sub panel - the problem I have is the neutral bus is full what are my options?
Best answer - If panel can accept, add an additional bus on the other side and bond the two together. Least desirable answer - split bolt the neutral to one of the existing. Under no circumstances should you place multiple wires under one terminal. <<>> The neutral wire for the sub panel will only be a #10 conductor. Neutral wires can be doubled up under a single screw in the neutral bus. Turn the main breaker off to do this installation. Double up two #14 neutrals to make room for the #10 neutral wire. There is no code rule as to how many wires can be installed under a terminal on the neutral bus. There is a code rule though about not doubling up circuit feeders under one breaker terminal.
What are isolators used for in optics?
An isolator that is related to optics is called an optic isolator. This is a component that will allow light to only be transmitted in one direction.
What is difference bitween air break switch and load break switch?
Both are types of isolators of a power circuit. Load break switch is an isolator where circuit can be isolated on load. The quenching media could be air, oil or gas..... Air break switch is type isolator where isolation takes place in the air itself. (break contacts are not immersed in oil, gas ...) But whether these isolators can be opened on load or not can be said only by looking at the desgin data. Some isolators are designed to open and close on load.
Are CANDU nuclear power stations operated only in Canada?
No.
What are the types of isolator?
there are two types mainly... off load and on load on load isolators are those which can break the circuit when the supply is still there. off load breakers cannont do that. the can only operate when there is no supply.
Where isolators are placed in substation?
An isolator is a non load-breaking switch, and is provides a visible means of isolating a component, such as a circuit breaker, transformer, etc., from the high-voltage lines, whenever it is necessary to perform maintenance of that component. Normally, isolators come in pairs, with one on each side of the component to be isolated. Isolators are only opened afterthe load current has been broken using a circuit breaker, and must be closed before the circuit breaker is reclosed.To work on, say, a h.v. circuit breaker, the breaker must be tripped, the isolators on either side must be opened and locked off, temporary earths attached to either side of the circuit breake- to-work card, detailing the maintenance work, must be issued to the crew by the supervising engineer.
Do you have to have a cdl to drive a new 26001 truck to it's owner?
The only times a vehicle of that weight doesn't need a CDL is when the following conditions are met:It's a registered recreational vehicle, and is not being operated on a for-hire basisIt's a registered farm vehicle, being operated on a not for-hire basis within 150 miles of the farm, and being operated by the farmer, members of their immediate family, or direct employees of the farmerIt's a military vehicle being operated by military personnel in the course of their dutiesIt's a firefighting or first response vehicle being operated by first responders in the course of their dutiesKeeping in mind that it must be registered as such BEFOREHAND, you're only exempt from needing a CDL under those conditions. Otherwise, you need a CDL.
Where can you ride a segway in Ohio for 12 years of age?
Ohio law requires you to be at least 14 years of age to operate a segway, and then only under the supervision of an adult. At age 16, it can be operated without restrictions.
Why is only 1 tire spinning on your fourwheeler?
Only one wheel spins on battery operated four wheeler
Can a clutch on a Ford Escort be adjusted?
Yes. You don't say what age and model, but most have cable operated clutches and there is an adjuster where the cables attaches to the gearbox, under the bonnet. This only adjusts the pedal height and operating stroke. A slipping clutch can only be cured by replacement.
What is the synonym for Cessna?
There isn't a synonym for Cessna... Cessna has always been Cessna, has not operated under any other names, and has always operated independently of parent companies which had bought it out (General Dynamics from 1985 to 1992, and Textron from 1992 to present). Only two products from another company are manufactured under the Cessna name - the Columbia 350 (as the Cessna 350) and the Columbia 400 (as the Cessna 400). Cessna is Cessna... nothing else is.
Why does a Ford Fiesta heater only blows hot?
The heater control valve can stick open or closed, as it is operated by an electrical solenoid. Clean old valve, or a new one. Located under bonnet, near bulkhead
Do you need a license to operate a track hoe?
