As long as the voltage insulation factor of the conductors are the same and they are of the same circuit fed by the primary side of the transformer's disconnect switch then yes the two feeders can be run together. It is not usually done though because the Transformers feeders usually start at an MCC or splitter of one voltage and the load side of the transformer usually goes to a distribution point of some sort at a different voltage.
Any wire size larger that a # 18 AWG can be fused at 2 amps.
You will have to check with the local electrical inspector for a ruling on the distance. Different countries have their own regulations on this. It all has to do with the amount of un-fused conductor that jurisdictions allow inside the house before the first over current device. This is usually the distribution panel's main breaker. Any short circuit in the mast head stack could run into the tens of thousands of amps as the only protection will be the utility transformer's primary fuse. The utility company has a habit of over fusing their transformers, some times by 300 to 400%. This is done to stop nuisance tripping.
Yes. As long as you are not in violation of the 10ft.,25ft or 100ft tap rule. Each XFMR should be fused @ 125% FLA. as such secondary does not have to have a main breaker. RK Class 5 fuses should be used.
The Related Link shows a transformer inside a metal cabinet, supplied with 120VAC protected by a fuse and the standard neutral connection back to the supply. There is a ground connection from the supply to ground, but there is no ground connection shown for the metal cabinet.The question asks, if the (fused) hot side of the transformer shorts to the metal cabinet, will the fuse blow?The answer depends on whether or not the metal cabinet is grounded.If it is not grounded, as implied in the diagram, then the fuse will not blow, because there is no circuit formed to do so. Additionally, AND MORE CRITICALLY, this would energize the metal cabinet, creating an electrocution hazard.However, it must be noted that per the NEC (US) and most probably any other country's electrical code, such a metal cabinet MUST be grounded.IF, AND ONLY IF, the metal cabinet is grounded, then the fuse will blow, due to the additional fact that neutral and ground are connected together at the distribution panel (again, by code), and again, at the service entrance, and this will form a high current circuit sufficient to blow the fuse and prevent an electrocution hazard.FYI - If I encountered such an ungrounded condition in a metal cabinet, I would do everything in my power to cause the installing electrician to lose his or her license. Additionally, if this caused an electrocution (whether fatal or not) I would sue said electrician for everything they were worth, and I would probably win, even though that would not bring back the person that died. This type of malfeasance should not and cannot be tolerated.
A circuit breaker is designed to 'break' in a circuit if a short circuit (or other malfunction) occurs. This prevents overheating (or burn-out) of the circuit wires. In older systems, you would need to find which fuse wire has fused and replace it. In a circuit breaker, once the fault has been found and corrected, the breaker is simply switched back on.
Some small control transformers have a built in primary fuse. Larger transformers are primary fused externally and pole transformers are primary fused externally with the fuse holders mounted on cross arms near the transformer.
A fused bulb does not light up asno current passes through its filament. by j.gayathri
No, electricity cannot pass through a fused bulb because the filament inside the bulb is broken when it fuses, creating an open circuit that prevents the flow of electricity.
No, a fused bulb does not allow electricity to pass through. When a bulb is fused, it means that the filament inside the bulb has broken, interrupting the flow of electricity and causing the bulb to stop working.
Fused silica has 2 meanings: previously fused silica and presently fused silica. Previously fused silica is fused by heating it to its melting point. This can be done in crucible in a furnace. Presently fused silica is already hot and fused. Note: melted silica is probably a conductor, at least melted glass is a conductor.
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
During this electrolysis are obtained chlorine and sodium.
Fused silica is an engineering-quality, amorphous version of quartz. Source: http://www.makeitfrom.com/material-data/?for=Fused-Silica-Fused-Quartz
If the bulb lights up then electricity is passing through the bulb. If the bulb doesn't light up then electricity is not passing through.
Bat digits aren't fused. The ulnar and radius is fused but the digits are separate, the digits in the forelimb are linked by a membrane called chiropatagium. In case you were referring to the metacarpals and phalanges they're not fused.

None of the koala's fingers are fused together. The second and third toe of the koala's hind feet are fused together.
