What does a 3 pole circuit breaker do?
It provides power to 3 conductors simultaneously, and more importantly, disconnects all three conductors simultaneously in case of a fault. A three pole breaker is used with a three phase power system.
Is line to line fault a 3 phase fault?
'Line conductors' are the three 'hot' conductors (A-B-C) that connect a three-phase supply to a three-phase load. In some cases, a pair of line conductors (e.g. A-B, B-C, or C-A) is used to supply a single-phase load. A 'line fault' can be a short-circuit fault between all three, or any two, of these line conductors -whether they supply a three-phase load or a single-phase load.
Are the three conductors in a single phase 240v circuit considered to be in parallel?
If the three conductors are in a single cable they physically are positioned parallel in relationship to each other. True parallel conductors are combined to split the current. They have to be of equal length and size so that they split the load current between the two or three or four conductors. Conductors are paralleled so that multiple smaller conductors, which are easier to work with, can carry equally the total load current. To answer the question no, the three conductors in a 120/240 circuit are not considered to be in parallel. All three of these conductors could have a different current being carried by them depending on how the load is distributed.
Can triplex be run in underground conduit?
YesIn Canada the answer is no. Triplex is an aerial rated set of conductors that are used to bring the voltage from the utilities pole to the service drop at the home. Triplex consists of two ungrounded conductors wrapped around a neutral steel supported conductor. These conductors can be used on higher current capacities due to the direct cooling of the conductors by the surrounding air. This is why you will see a service drop of number 6 conductors supplying a 100 amp service. For a three phase four wire system quadplex is used to make three phase connections to commercial and industrial services.
What is phase conductor?
There is no such thing as a 'phase conductor'. The correct term is 'line conductor'. Line conductors are the three energised conductors that supply a three-phase load.

Why don't we use metal to power our homes?
We do, it is in the form of copper conductors.
What practical application do you have for insulators and conductors?
Carrying electrical power in homes and businesses.
How many voltage 3phase line?
For a three-phase, three-wire, system there are three conductors called 'line conductors', and there is a voltage between any pair of line conductors, so there are three voltages.For a three-phase, four-wire, system there are four conductors: three 'line conductors' and a 'neutral' conductor. So there are three line voltages (voltages between lines) and three phase voltages (voltages between any line conductor and a neutral conductor).

Why did the conductors of the underground railroad help enslave people escape?
The conductors of the underground railroad helped enslaved people escape mostly because they did not believe in the idea of slavery. The conductors used their homes and businesses to hide those people that were fleeing from the South because of slavery, before, during, and even after the Civil War.

What are 3 good electrical conductors?
Three conductors of electricity are metals, water and the human body.
What type of elements are used as conductors?
Metals and alloys are used as conductors: copper, aluminium, silver.
In what types of products are conductors used?
Conductors are used in every electrical product and device that is manufactured. Without the conductors there would be no path for the electricity to travel.
What examples of materials that are conductors?
All metals are conductors. Gold, silver, copper, aluminum and iron are used as conductors.
