The protective device should be rated not more than 10 Amperes and be able to withstand a 1000Ampere short circuit.

Can an extension cord plugged on a 230V socket outlet be used to connect a fully wired container with a distribution box?

You should know the maximum current drawn from the distribution box (in amps) and that must be less than the current that the extension cord is able to supply.


Can you have only one current carrying conductor in a conduit?

You can have only one current carrying conductor in a conduit, but that conduit must have a slot to relieve the eddy currents that will be created by the transformer effect created by the conductor. It is better to run the neutral or opposite conductor along with the hot conductor together in the same conduit, or through the same penetration, so as to minimize this effect.


Is it safe to cut and splice wire a normal 12v-125 amp 1625 watts max extension cord into a hanging light chandeliere fixture that has just two electrical wires?

I assume you mean 125v, 12 amps and 1625 watts max extension cord. This is not technically a proper installation but it should work. The concern is how long are you running the extension cord and how and where are you making the splices. There are a lot of issues at hand that cannot be answered without more information. Electricians generally dislike extension cords. Usually the conductors are small enough they will MELT AND BURN at a current flow that will NOT TRIP THE BREAKER. You should consider it temporary at best. It should not be forgotten nor hidden in a wall or ceiling under ANY circumstances.


When do you derate wires in conduit I know the code says more than 3 current carrying conductors but is there a length of conduit run when you should start to derate?

There are two things here to keep in mind. If you are trying to add more conductors to an existing conduit run use the cross sectional area of the conduit to see if more wires can be fitted. The second thing that's relates to length is the voltage drop at the load. To size the conduit work backwards from the load amperage to size the wires. If a long distance is involved a voltage drop calculation will be needed. Then select the conduit size to accommodate the wires recommended for that load amperage. The length of conduit run is not brought into the equation on de rating wire size it is always about keeping the voltage up at the load end of the run by increasing the wire size and selecting the proper conduit size for that wire.

Should the nuclear life extension program end?

If you mean the extension of current reactors, then no. As long as they are determined to be structurally sound after a thorough inspection.

What usually happens at consumer end when the current carrying capacity of transformer is exceeded?

What should happen is that the circuit-breaker should trip to cut off the current before the transformer becomes damaged by overheating.

What are five conditions that must be met for running conductors in parallel?

To run conductors in parallel, the following conditions must be met: first, all conductors must have the same length to ensure equal current distribution; second, they should have the same cross-sectional area to maintain consistent resistance; third, the materials used for the conductors must be identical to avoid differences in resistivity; fourth, the conductors should be insulated to prevent short circuits; and finally, the temperature rating of the conductors must be the same to ensure safe operation under varying thermal conditions.


How do you write application for extension of overdraft?

It is very easy to write an application letter for extension of overdraft. You should include all your personal details and explain the current position you are in. It is also important to specify how much time you need.

Should I Purchase A Current Business To Begin?

The benefit of purchasing a current business is, it has already been established in the market. It has clients and it is carrying on business. You steer clear of the hassle and cost of beginning on your own.


What are materials that allow electrons to move through them easily?

Materials that allow electrons to move through them easily are called conductors. Common examples of conductors include metals like copper, silver, and gold. The presence of free electrons in the material facilitates the easy flow of electrical current.


Do you have to ground a kitchen light?

Any fixture containing metal other than the conductors should be grounded. It ensures the proper operation of the over current device, which is the breaker or fuse.


Difference between neutral conductor and grounding conductor is that?

A Neutral represents a reference point within an electrical distribution system. Conductors connected to this reference point (Neutral) should, normally, be non current carrying conductors, sized to handle momentary faults (short circuits) occurring in electrical equipment. A Ground represents an electrical path, normally designed to carry fault current when a insulation breakdown occurs within electrical equipment. (Note: Breakdowns can be forced by connecting (dropping) a metal tool or conductive material from a voltage potential to the steel structure within a facility).
