If the load is single phase and the load requires 460 volts to operate, then two conductors will be needed and they will connect to a two pole breaker. If the load is three phase and the load requires 460 volts to operate, then three conductors will be needed and they will connected to a three pole breaker. The sizing of the wires will depend upon the current that is drawn by the loads.
Yes, it will be protected by a circuit breaker or fuse. The normal rating of the circuit breaker or fuse is 25% more than the maximum current expected, or the maximum current allowed for the cable size, whichever is lower.
There is no problem using over sized wires on a breaker. It is only when the wires are undersized that the trouble begins. Oversize wire on a breaker is very common practice when overcoming voltage drop on a circuit.
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.

the circuit breaker used will be miniature circuit breaker(MCB) maily used in homes.Answer for USA, Canada and countries running a 60 Hertz supply service.A two pole circuit breaker is used for a load of 240 volts. It is sized, according to the load amps of the device, to protect the wires that supply the load current.
Yes, it will be protected by a circuit breaker or fuse. The normal rating of the circuit breaker or fuse is 25% more than the maximum current expected, or the maximum current allowed for the cable size, whichever is lower.
A fuse or circuit breaker used in a circuit is usually inserted in series with the load.

Fuse
A fuse or circuit breaker will fit this description.
A breaker is a device that is used to connect and disconnect the buss bars of an electrical panel to the feed end of wires that feed an electrical load. The function of a breaker is to protect the wires from an overload by the use of an internal thermal trip, and to protect the load and wires from a short circuit by use of an internal magnetic trip.
They are completely different. A moulded-case circuit breaker is a low- or medium-voltage device, whereas an air circuit breaker is a very large circuit breaker designed for use in high-voltage transmission/distribution substations.
Vacuum circuit breaker is used in railway applications and as it is used in the applications where current chopping phenomenon is more
