A two pole breaker protects both L1 and L2 legs. An over current on either leg will trip the breaker.

Single or Three phase Ac Circuit?

Both are possible. Single phase requires a neutral (or two phases, such as "Single-phase 240 V) to return the un-used voltage on the "down side" of the generating cycle. Three phases equal "each other out" on the up and down side. One phase generating positively while the other two are at various points of positive and negative on the sine wave to balance each other out.


Why cant take connection from phase line to neutral line?

A connection can be taken between phase lines, or between one phase and neutral. Both methods give a single-phase supply. Between phases the voltage is sqrt(3) times more than between one phase and neutral. In each case the load gives an unbalanced current on the 3-phase system but the idea is to average out the unbalances over a group of single-phase loads.


How to parallel the Dyn1 and Dyn11 Transformer?

you keep the hv & lv on the dyn11 tx straight in phasing. you then put a cross on any two phases on the hv side of the dyn1 tx, and do the same cross with the phases on the lv side of the tx. for instance lets say we cross a & c phases on the hv & lv sides of the dyn1 tx. now draw a diagram with the four tx, split them up, 2 x dyn1, 2 x dyn11. now on the diagram where you have dyn1 tx, change the the phase plates to read cba left to right, also change the lv side to match. leave the phase plates on the dyn11 tx alone to read abc left to right on both sides. now draw the cables going between them on the hv & lv sides. now if a phase always goes to a phase and b & c phases do the same it will all tie in. prove it to yourself and follow a phase threw all the tx's, do the same will b & c phases. I do it all the time at my job, works every time.


Difference between 3 pole and 3 phase?

Phases in AC refer to the number of sine waves of alternating current used to generate the average voltage. In 2 phase, two opposing sine waves are overlapped to give the average voltage delivered, eg 240V in household supplies. In 3 phase, three sine waves are overlapped to produce a more consistent average voltage.


You work with nitrogen pony bottles as a portable source for compressed gas When full the internal pressure is about 2200psi Is the nitrogen a gas or is it in a two phase gasliquid state at 300k?

Neither, the nitrogen is in it's super critical phase. if both T and P are greater than or equal to 126.2K or 33.54 ATM the two phases are indistinguishable.

What does the line on a phase diagram represents?

The line on a phase diagram represents the equilibrium between two phases at a specific temperature and pressure where both phases can coexist. It shows the conditions under which the phases transition from one to the other.


Phase diagram of aluminium copper alloy?

The phase diagram of an aluminum-copper alloy typically shows two phases: a solid solution phase (α-phase) and a eutectic phase (θ-phase). As the temperature decreases, the α-phase solidifies first, followed by the eutectic reaction where both phases form simultaneously. The diagram helps in understanding the temperature and composition ranges where different phases exist in the alloy.


When are two phases at equilibrium?

Two phases are at equilibrium when the rate of their interconversion is equal in both directions. This means that the amount of substance transitioning from one phase to another is the same in both directions, resulting in a stable balance between the phases.


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.


How are phase 1 and phase 2 of logistic growth similar?

Phase 1 and phase 2 of logistic growth are similar because a population is increasing, moving toward its carrying capacity during both phases.


What is the different between the terms state and Phase?

You can have multiple phases in the same state. For example: If you pour oil and water together they form two phases (an oil phase and a water phase), but both of them are in the liquid state. Another example is sulfur. Sulfur heated to above its melting point and then cooled suddenly (by drizzling it into cold water, for example) forms a rubbery solid that slowly turns back into the usual yellow form. Both the rubbery material and the regular yellow crystalline sulfur are solids, and they're both sulfur, but they're different phases. Two things that are in different states, though, are always different phases.

What are in PHASE?

Two different liquids (by example water and oil) can exist together in two liquid phases which both can be solutions with the same solute.


What are the phases of Phobos and Deimos?

Both Phobos and Deimos, the two moons of Mars, go through phases similar to our Moon. As they orbit Mars, their illumination changes until reach full moon phase with the entire disk visible, then waning to a new moon phase where they are not visible at all. These phases are caused by the changing relative positions of the Sun, moon, and Mars.

What is a balanced three phase system?

A balanced three phase system is where the currents into the loads placed on all three phases of the service are reasonably close to each other in amperage.Another opinionA 'balanced' three-phase system describes a three-phase load in which each phase current is identical in both magnitude and phase. If the phase currents are only 'reasonably close', then the load is not balanced.


What would cause 54 volts on both phases at the meter multiple homes affected?

You might only have one phase supplying the homes. Call your power supplier.
