Why is post production essential?
to ensure the system will continue to be sustained after production lines have closed.
Are all voltages in a circuit referenced to ground?
Typically yes, but not always: you can also measure the voltage between any two points in a circuit to determine the voltage difference between those two points. It all depends what you are trying to find out about the circuit.Another example of a voltage that is not referenced to ground is the phase-to-phase voltage in a 3-phase electrical service.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Why did Peter the Great retrain Russian military after touring Europe?
to ensure their strength and loyalty
What do engineers need to consider when designing a space capsule to protect an astronaut?
engineers ensure the space capsule had carry oxygen for ensure combustion
In what episode of Case Closed did Shinichi Kudou first tell Hattori Heiji that it was a detective's job to ensure the criminal didn't commit suicide?
I think it is in season four episode 100. It is called The Memories of First Love, Part 2. Conan says that because he was once unable to save a murderer from commiting suicide in the Moonlight Sonata Case Part 2.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
How to bypass single phase circuit breaker?
You should never try to bypass any protection devices. This is just asking for trouble down the road. The circuit breaker is there to protect the wiring to the device that is powered from that breaker. If the load is too large and keeps tripping the breaker install a larger breaker with new wiring sized to the breaker to accommodate the higher load current. Again do not bypass circuit breakers as you will have no short circuit or overload protection.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Purpose of a breaker in an electrical circuit?
Breakers ensure that when too much amperage is being drawn through the circuit the power is shut off. Excessive amperage creates heat. Without a breaker that heat buildup could lead to fire.
Can you deliver power from a gfci outlet to 3 fans?
You could if you ensure that the fans won't overload the circuit and that the added wiring is sufficient. 12 AWG for a 20 A breaker and 14 AWG for 15 A breaker
Why is closed circuit television cctv used in casinos?
CCTV is used in casinos to monitor activities of the guests and employees. This is to ensure that there is no cheating going on and to ensure the security of all.
Can you wire 15 amp plug on a 20 amp circuit?
No. Also it would be a moot point using a 20 amp receptacle because the breaker protecting the circuit will only be a 15 amp. If you use a 20 amp breaker then make sure that the wire size is #12 and that you remove the 15 amp receptacle from the circuit as it will be not rated for the new 20 amp current.
Where can I find a good deal on a closed circuit tv?
Try Amazon.com. It has a closed circuit TV for a cheap price and it's definitely a bargain! Make sure you find a seller with a great reputation to ensure that your TV is of an excellent quality. Here is a link to a closed circuit TV that is being sold on Amazon for cheap: http://www.amazon.com/gp/search/ref=sr_nr_i_7?rh=k%3Aclosed+circuit+tv%2Ci%3Advd&keywords=closed+circuit+tv&ie=UTF8&qid=1308186308#/ref=nb_sb_noss?url=search-alias%3Ddvd&field-keywords=closed+circuit+Television&rh=n%3A130%2Ck%3Aclosed+circuit+Television
What is the operation of isolator?
An 'isolation transformer' is a 1:1 ratio mutual transformer. It electrically isolates the secondary circuit from the primary circuit without changing the voltage level. A bathroom shaver socket uses an isolation transformer.
How do add an extra socket without breaking the circuit?
The key is to ensure that a 15amp breaker has no more than 6 220-240V wall sockets,if more than 6, the extra sockets must be serviced by a different breaker to avoid overloading the D.B
What are the applications of autorecloser?
An autorecloser is a feature built into a high-voltage circuit breaker. In the event of a transient fault (e.g. a tree branch hitting a conductor) to an overhead line, the circuit breaker will trip and disconnect the line. However, the autoreclosing feature will then automatically reclose the circuit breaker. If the fault has cleared itself, then the line will remain energised. If the fault persists, then the autorecloser attempt to reclose the circuit breaker a set number of times before locking the circuit breaker open.The number of times the autorecloser feature will attempt to reclose the circuit breaker, and the duration between attempts, can be set by the protection engineers.This autoreclosing feature of circuit breakers is often used in conjunction with sectionalisers. These are pole-mounted switches which are located at different points along a power line. When the circuit breaker trips, in response to a line fault, the furthest sectionaliser along the line disconnects the furthest section of line. If the fault remains when the circuit breaker then recloses, the next nearer sectionaliser disconnects the line from its location. This action continues, until the permanently-faulty section of line has been disconnected. This system tries to ensure that as much of the healthy part of the power line remains in use as possible, following a permanent fault.
Why won't the switch on my breaker box stay on?
This is properly understood when Ohm's Law is applied: Voltage, Amperege and Resistance are correctly applied to a circuit for it's correct function. The circuit breaker acts as a protective device and trips when a correct electrical circuit does not exist. The wrong breaker may have been installed. the wrong gauge of wire may have been used, the pumps and heaters may be drawing more amps then planned for or a short circuit or loose connection are all possible faults. Contact the electrician that installed the system for resolution of the problem or an outside electrician if the problem isn't corrected. Caution: Water and Electricity should not be trusted when in close proximity.
What size ciruit breaker needed to run a 110v heater 500 watts?
That will draw about 9 amps at 120V. A 15 amp breaker if the circuit conductor is #14 or 20 amp breaker if the circuit conductor is #12. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
