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).
What three colors are ungrounded conductors not permitted to be on a conductor?
White, grey, and green are the three colors that ungrounded conductors are not permitted to be on a conductor.
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.
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.
What are three materials that are good conductors of heat?
Copper, aluminum, and silver are three materials that are good conductors of heat due to their high thermal conductivity properties.
What are three bad conductors?
wood, glass, textile

What are three general of metals?
Conductors of heat, malleable,shiny
List three materials that are good conductors?
Copper, aluminum, and gold are examples of good conductors of electricity.
How many current carrying conductors can you have in a conduit before you have to start derating amparage?
The number of current-carrying conductors allowed in a conduit before derating is specified by the National Electrical Code (NEC). Generally, if you have more than three conductors in a conduit, you need to start derating the ampacity of the conductors. Specifically, for more than three conductors, the ampacity of each conductor must be reduced based on the number of conductors present. For example, with 4 to 6 conductors, the ampacity is typically reduced to 80%, and with 7 to 9 conductors, it’s reduced to 70%.
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.
Why we called it three phase?
Because there are three positive charged conductors and there is electrical pressure in between.
