Difference between live and neutral wires - Physics Stack Exchange With the neutral implemented, we get constant voltage accross any load (impedance) with varying current How does the neutral wire make this possible? Since the neutral wire is a potential between all three phases, each phase along with the neutral wire can form an independent circuit e g your house, hence live and neutral
Why are all the neutral wires in a sub panel burnt or melted? All of the neutral wires had around an inch of melted plastic that was the wire insulation and several inches of blacked burnt plastic going up the wire One of the neutrals (the one for the circuit that stopped working) was loose, since it had melted right through -- the hole in the neutral bar is filled with previously molten copper and or
Can two circuits share a neutral? - Home Improvement Stack Exchange A multi-wire branch circuit (two hots from different legs sharing 1 neutral) is often found in the kitchen where it powers one receptacle which has the jumper connecting the upper and lower outets removed The result is that you get two 15amps circuits at one receptacle At the panel, both breakers should be bonded together so it is not possible to have one on and one off Code varies by
Why dont we get a shock touching neutral wire? The neutral wire does have current going through it However, we do not get shocked when we touch something with current going through it, we get shocked when current goes through us In this case all of the current that enters one end of the section of wire we are touching also leaves the other end None goes through us so we don’t get shocked
electrical - Is it ok to have mixed grounds and neutrals on bars in a . . . When you tie neutral to earth ground in a subpanel, you create a potential parallel path for current to return via earth (ground) In the event of a fault, your ground conductor has assumed the role of the return path for current and now everything that you've grounded (sub-panel, appliances, metal fixtures, etc) to that sub-panel is now hot
Why am I showing 50 volts between neutral and ground? If I test the ground and the neutral mid-line (at a junction box between two of the lights), I am getting 50 volts Neutral to hot reads 120 volts, and hot to ground reads 66 volts at the same junction box
Does a 240v water heater circuit require a neutral? Note that new switch loops in many locations require neutral, in which case black red white, white being neutral, black always hot, red switched hot (though technically it could be red always hot, black switched hot ) 240V circuit - In a 240V circuit (no 120V needed), you only need two wires carrying current (the ground wire is different)
Acceptable voltage between earth, Line,Neutral - Single Phase I have a 240V+-10V 2 Wire Single Phase (UK) supply Note that standard UK supply spec nowadays is 230V +10% -6% (yes the tolerance thresholds are asymmetric) This gives an acceptable voltage range of 216 2V - 253V What is an acceptable voltage between Live Line and Earth? The voltage between Line and Earth should be similar to the voltage between Line and Neutral What is an acceptable
