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.
The synchronous speed of a four pole 60 hz single phase motor is?
3600 rpm
What size should under ground conduit be from pole to meter base?
For new 200 amp services the conduit size should be 3 inch PVC.
Can a double pole circuit breaker be used for 2 different circuits I have a 20 amp double pole breaker want 2 circuits running 14 gauge wire?
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
How single-phase induction motor classified?
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
Can a 2 pole breaker to protect 1 phase circuits and 2 phase circuits?
Probably
Two phase instruments?
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
If you are making your own device and you bring in 208 3 phase for part of your needs - how can you properly tap 110 single phase from it to operate other parts of your device?
Your incoming 208V 3 phase power supply will also need an incoming neutral of the same conductor size. Then any single pole breaker installed in the panel will have 110 volts to the neutral. That is you can run 208V 3 phase motor circuits from a three phase breakers in the panel and any number of 110V circuits from single pole breakers.
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 difference between using 4poles circuit breaker and using 3 single pole breakers?
3 pole would be for 3 phase, 4 pole would be 3 phase & neutral
How many different types of alternator are there for a 1998 fore contour?
type 1: single phase tree phase poly phase type 2: rotating armature rotating field type 3: salient pole machine non salient pole machine type 1: single phase tree phase poly phase type 2: rotating armature rotating field type 3: salient pole machine non salient pole machine
Can a 220 VAC breaker be single pole or does it have to always be a double pole breaker?
A 220 VAC breaker can be single pole or double pole depending on the application. For standard 220 VAC circuits like most household appliances, a double pole breaker is typically used. However, in certain situations where only one hot wire is needed, a single pole breaker can be used for 220 VAC circuits.
How do you convert a 0.37kw 4 pole 3 phase motor to single phase?
The motor cannot be altered to work on single phase power. You will either have to put in a new single phase motor or use a phase convertor box. Do a google search for phase convertor - you will find plenty.
Should you buy double pole breaker or single pole?
It depends on the specific requirements of your electrical system. Single pole breakers are typically used for 120-volt circuits, while double pole breakers are used for 240-volt circuits. If you are unsure, it is recommended to consult with a qualified electrician to determine the appropriate type of breaker for your needs.
Is a 3 phase cable one circuit?
If it is powering a single 3 phase device and is protected by a single throw 3 pole breaker or disconnect, yes. If all three hots share one neutral, and supply different devices or circuits, breakers should be able to trip independently but would still have to disconnect all three phases together.
