Why no electric shock from neutral line?
There is normally no voltage on the neutral line because the neutral line is grounded. However, and this is always important, do not assume that neutral is grounded, nor that there is not an elevated voltage on neutral or ground due to a possible ground fault.
What is the minimum size neutral for three sets of parallel 500kcm copper conductors for a service?
On large service entrance services the neutral can be reduced. The amperage of the service and the voltage of the service and the insulation factor of the 500 MCM conductors need to be stated to answer this question correctly.
How are voltages imported into installations through the supply neutral conductor?
A 'voltage' is another name for a potential difference. As the name implies, a potential difference exists between two different points or, in the case of an electrical installation, between the line conductor and the neutral conductor. So the neutral does not 'import voltages'. Voltages exist between the line (hot) conductor and the neutral conductor.
What is use of neutral link?
In a MEN (Multiple Earth Neutral) system, the neutral wire is connected to the earth wire at the switchboard. This is the neutral link. From an electrical point of view the neutral pin and the earth pin in a power socket are at the same potential but from a safety point of view they are different. A residual current device (RCD) (or earth leakage core-balance-relay(ELCBR)) sits in series with both the active and the neutral feed and a leakage from either wire to ground (via a human or water leak in a washing machine etc) will trip the circuit breaker that is in the RCD.Another AnswerFuses or circuit breakers must be inserted into the line conductor, never into the neutral conductor. However, if we need to isolate the circuit, we must place a break in both the line and the neutral conductors. We can achieve this for the line conductor by, for example, removing the fuse. To achieve the same with the neutral conductor, we can open the neutral link, which is simply a short length of conductor inserted between a pair of terminals in the neutral.
Which colour wire is live in UK wiring?
In a flexible cable, the brown is the "line" voltage and blue is "neutral", often tied to ground at the mains panel. In fixed cables, i.e., "behind the walls", the UK wiring standard changed in 2004, where it now MATCHES the flexible cable: brown is line, blue is neutral. Prior to that, blue, red or yellow were acceptable LINE conductor colors and black was neutral.
What do the electrical symbols L and N and A stand for when referring to live and neutral etc?
line neutral amperage

How do you size the neutral in a 240 volt system?
On a 120/240 volt distribution the neutral is sized along with the supply conductors. The sizing is based on the amperage of the service distribution.
When the neutral switch is open where do the line current flow to?
There is never a switch installed in a neutral line.
How many watts does a compact fluorescent bulb draw?
Look for an amperage on the ballast. Multiply this amperage by the connected line voltage. This will give you the wattage of the unit.
Is the blue line a part of the neutral zone?
The blue line is what separates the neutral zone from a team's offensive and defensive zones.
Is it possible to connect 3 phase 440 V without neutral line to the machine having 3 phase 4 wires with neutral line?
No, it is not possible to connect a 3-phase 440 V system without a neutral line to a machine that requires a 3-phase 4-wire connection with a neutral line. The neutral line must be present in both systems for proper operation and safety. Trying to connect them without the neutral line could cause damage to the machine and pose a safety hazard.
If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage.CommentThere is no such thing as a 'phase to phase', or 'phase to neutral' voltage. The correct terms are 'line to line' and 'line to neutral'. So the above answer should read: line voltage/1.73= line to neutral voltage = phase voltage.
How do you find neutral line among distribution lines?
US NEC: The neutral line is the white wire. Coming from the pole, it is the ground wire.
