What else can I help you with?
What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt
What is the Largest amperage single phase 120 volt breaker made?
6000amps <<>> The above answer must have big lugs to accommodate 6000 amp capacity wire. In my breaker catalogue the largest 120 volt single pole breaker is 70 amps, 277 volt single pole is 150 amps and 347 volt single pole is 100 amps. The 120 volt single pole breaker occupies two opposed slots because of its length.
Can you use a 240 volt 3 phase disconnect with 460 volt?
It's possible, but not at all economic. Usually the 240V (sure it's not 277?) has been stepped down from 480V service already. Sounds like this is a commercial application. 480 is rare in residential, but quite common in commercial. If you need 480, you'll need to get ahead of the step down transformer.AnswerYou cannot obtain a three-phase supply from a single-phase supply.
You are measuring 480 volt from phase to phase and 280 volt phase to ground but one leg measures 440 volt phase to ground why?
Check for a blown fuse in one of the phase legs.
Can a 230 volt single phase watt hour meter be used to monitor 115 volt single phase?
Yes it would work pretty well but it might not meet its accuracy specification.
Can you use a 2 pole breaker for a 120 volt single phase circuit?
No, a 2 pole breaker is designed for a 240-volt circuit or for two separate 120-volt circuits that are out of phase with each other. For a 120-volt single-phase circuit, you would typically use a single-pole breaker.
What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt
How many poles are required on motor starters for the following motors a240-volt single-phase induction motor b440-volt three-phase induction motor?
For a 240-volt single-phase induction motor, a two-pole motor starter is typically required, as it connects to the two live conductors of the single-phase supply. For a 440-volt three-phase induction motor, a three-pole motor starter is needed, as it connects to the three phases of the three-phase supply.

What are the differences between a single pole and a double pole breaker?
A single pole breaker controls one wire and is used for 120-volt circuits, while a double pole breaker controls two wires and is used for 240-volt circuits.
Can a 3 pole100 amp600 volt disconnect be used in a 3 phase 250 volt application?
Yes - Most switches have two positions for the fuses. The bottom of the bracket for the fuse holders can be moved up to accommodate the shorter 250V fuses.
What is the difference between a single pole and a double pole breaker?
A single pole breaker controls one hot wire and is used for 120-volt circuits, while a double pole breaker controls two hot wires and is used for 240-volt circuits.
What is dpst switch?
Double pole Single Throw switches are sometimes called DPST switches. Assuming the circuit is single phase two wire system, DPST - are used to isolate the ciruit. Isoloation occurs on both terminals hence it is called double pole. This isolation occurs at only one end in the circuit, hence it is called single throw.
You are measuring 480 volt from phase to phase and 280 volt phase to ground but one leg measures 440 volt phase to ground why?
Check for a blown fuse in one of the phase legs.
Is there a 277 volt 2 pole breaker?
Yes, 277-volt 2-pole breakers are available and commonly used in commercial and industrial applications, particularly for lighting and HVAC systems. These breakers are designed to handle the specific voltage and are typically found in three-phase electrical systems. When selecting a breaker, ensure it meets the required specifications for your application and complies with local electrical codes.
Can a 230 volt single phase watt hour meter be used to monitor 115 volt single phase?
Yes it would work pretty well but it might not meet its accuracy specification.
