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.
What else can I help you with?
A small appliance circuit will be protected by a circuit breaker rated at?
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.
What is a circuit breaker with 2 switches?
A circuit breaker with 2 switches typically refers to a double-pole circuit breaker. This type of circuit breaker has two separate switches that simultaneously disconnect both the positive and negative wires of a circuit, providing complete electrical isolation. It is commonly used for appliances or devices that require a dedicated electrical connection.
How is the rating of the branch circuit protective device affected when conductors used are of larger size than called for by the code?
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.
What device is used for turning a circuit on or off?
Circuit breaker or switch
What does single pole and double pole mean on a twenty four vault circuit?
Single pole refers to a circuit breaker that interrupts the current flow of one hot wire, while double pole interrupts the current flow of two hot wires simultaneously. In a 240-volt circuit, a double-pole breaker is used to control both the hot wires, providing higher safety protection as both sides of the circuit are disconnected.
What is the purpose of a double lugged breaker in an electrical circuit?
A double lugged breaker in an electrical circuit is used to provide additional connection points for wires, allowing for increased electrical capacity and distribution within the circuit.
What type of circuit breaker is required for a 240 v branch 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.

A fuse or circuit breaker used in a circuit is usually inserted in?
A fuse or circuit breaker used in a circuit is usually inserted in series with the load.

What is the purpose of a double pole 20 amp breaker in an electrical circuit?
A double pole 20 amp breaker in an electrical circuit is used to provide protection by simultaneously disconnecting both the hot and neutral wires in the circuit if there is an overload or short circuit. This helps prevent damage to the electrical system and reduces the risk of fire.
What device is used as a form of safety device in an electrical circuit?
A fuse or circuit breaker will fit this description.
What is the purpose of a double pole breaker in an electrical circuit?
A double pole breaker in an electrical circuit is used to disconnect both the hot and neutral wires simultaneously, providing a higher level of safety and protection against electrical hazards such as overloads and short circuits.
What are breakers?
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.
What is the purpose of a double pole 15 amp breaker in an electrical circuit?
A double pole 15 amp breaker in an electrical circuit is used to provide protection by simultaneously disconnecting both the hot and neutral wires in the circuit if there is an overload or short circuit. This helps prevent damage to the electrical system and reduces the risk of electrical fires.
