What two colors may be used for the ground conductor neutral?
What two colors may be used for the ground conductor (neutral)
Define earth voltage and neutral voltage?
As the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Current carried on a grounding conductor can result in objectionable or dangerous voltages appearing on equipment enclosures, so the installation of grounding conductors and neutral conductors is carefully defined in electrical regulations. Where a neutral conductor is used also to connect equipment enclosures to earth, care must be taken that the neutral conductor never rises to a high voltage with respect to local ground.
Where do you connect blue and brown wires in European and UK wiring?
These colour wires are used in European and UK wiring. The blue wire is used to the identify the neutral conductor and the brown wire is used to identify the "hot" conductor.In Canada and the US. The white wire is used to the identify the neutral conductor and the any colour but green is used to identify the "hot" conductor.
Which is the safest position for the switch when an appliance is used?
Your question is rather vague but, for a.c. systems, a switch must always be placed in the line conductor, neverthe neutral conductor.
What type of switch would be used to control a lighting load from one control point?
In this type of situation, where there is more than one lighting circuit, a lighting contactor would be used. These types of contactors can be obtained in four and five pole configurations. Make sure that the contactor is rated for lighting loads and not motor loads. A normal switch, single pole single throw, would be used to switch the contactors on and off. A single switch could then be used to control as many contactors as you need to operate the lighting circuits.If there is just one lighting circuit, the total circuit amperage must be known, then the switch would be sized to the amperage of the circuit.
What is an grounding electrode conductor?
It is the conductor that is used in service distribution panels that bonds the distribution panel's neutral bus bar to the ground electrode (rod). This brings all of the distribution panel neutrals that are connected to the same supply system to the same potential, that being zero. Should a supply service neutral open this ground wire will maintain the systems integrity until repairs can be made.
What are some things that use sodium?
Sodium, first of all, is a coating for fertilizers,wires, and sometimes used in lighting. It also shines with a glow of yellow light, for lighting. Sodium is a soft, electr. conductor. =]]]]--------------->
Is the ground wire safe to be the hotwire?
No. A ground wire is a non-current carrying conductor and cannot be used for hot or neutral.
Why in electrical wiring you need both neutral and ground if neutral is zero voltage why you cannot used it as a ground?
The neutral is a current-carrying conductor, the grounding wire is not; it is for safety as an ALTERNATE path to ground. For example, if something happens to disconnect the neutral or if the hot side comes into contact with conductive portions of an appliance, the grounding conductor can save a life by providing a safe fault mechanism.
What is an AC single phase 2 wire system?
two wires coming off the secondary of the transformer ex. residential voltage of 120 volts each line, and one neutral wire, L1 to neutral is 120 volts, L2 to neutral is 120 volts, L1 to L2 is 240 volts.AnswerA single-phase, two-wire, system comprises a line conductor and a neutral conductor. In European countries, the line conductor for a residential supply is at a nominal potential of 230 V with respect to the neutral.In North America, a 'split phase' system is used for residential supplies; this is a single-phase, three-wire, system comprising two line conductors which and a neutral conductor. The nominal potential difference between the line conductor is 240 V, while the potential of each line conductor with respect to the neutral is 120 V.
What colour are the phase neutral and earth cores flexible cords?
Flexible cord colours are, White for neutral and Green for ground.AnswerIt depends on the standards used in your country. The above answer refers to North America. In Europe, the colours are brown for the line (not 'phase'!) conductor, blue for the neutral conductor, and green/yellow stripe for the earth (ground) conductor. For European three-phase systems, the lines are coloured brown, black, and grey.
Why can the neutral wire diameter be reduced in relationship to the phase wires?
The Neutral wire should be the same gauge and size of the phase wires. Only the Earth or Equipment wire can be smaller than the phase(hot) wires. <<>> On a three phase four wire distribution system the neutral can be reduced in size. The neutral only carries the unbalanced load current and should be sized to that current. The highest current load to neutral of the three legs is used to calculate the neutral sizing. There is no reduced neutral allowed on discharge lighting and non linear loads. A demand factor of 70% shall be permitted to be applied to that portion of the unbalanced load in excess of 200 A.
