Why is it on a 240V line you tested with a circuit tester you have a bright glow between neutral and one hot a light glow between hots and nothing between the other hot and neutral?

Maybe the breaker for one "hot" has tripped open or its fuse has blown on the main supply panel? If that is what has happened it would show up just as you describe: * the bright glow between neutral and one hot is as normal and shows it is "live";
* the light glow between hots is from the live hot that is ok and the neutral on the other side of any appliances that are still wired (or plugged) into both hots and neutral. If you disconnect or unplug any appliances (dryer, water heater, etc.) that glow will go away.
* Nothing between the other hot and neutral is because that hot is not being powered. If that is the case, because its fuse has blown or its breaker has tripped, the reason why that happened must be found. * It could be that an appliance has developed a fault, such as a short to ground or something similar, which caused a protection device to cut that circuit. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What happens if phase wire touch to earthing?
When a phase line touches the neutral by any conducting material means the Short Circuit. If there is a short circuit then the current in that circuit will be much higher and this increase in current may damage the the devices that are connected to that line.
What makes a light shine bright in circuit just a simple explanation please?
If it is brighter than it should be there is too much current and it will burn out early. This is usually caused by internal problems in the lightbulb, but could rarely be caused by excessive voltage in the circuit powering the lightbulb.
Why do manufactures protect the Vehicle Headlight with circuit breaker instead of fuse?
Vehicle headlights are protected with circuit breakers instead of fuses because, when light bulbs fail, there is an ionizing arc internally that causes high current. You see that at home - when a light bulb fails you see an instant of very bright light.This pulse of high current can blow a fuse. It also can trip a circuit breaker, but the circuit breaker is designed to reclose while, once a fuse is blown, it stays blown. Headlights are a critical safety device. It is better to attempt automatic reclosure following a fault, than it is to leave the headlights off, in case the fault was temporary.
Why dont series circuits shine as bright as parallel circuits?
By connecting components in series, you are increasing the equivalent resistance (known as thevenin resistance) of the circuit. Power is equivalent to Voltage^2 / Resistance. Therefore, by increase the resistance, you are decreasing the amount of power provided by the source.
Is there a bright future in java?
Yes, there is a very bright future in store for Java. It is very important to PC's.

Bright Nothing World was created in 2010.
What is the difference between violet and magenta?
Violet is a dark-neutral purple, while Magenta is a bright reddish-pink, very similar to hot pink.
Why are black and white a neutral colors?
because it has no natural color or.......bright color:)
Is series or parallel circuit cheaper?
A parallel circuit is cheaper because it is simpler but it does carry less power than a circuit so your light will be less bright.
What ultra-bright colors were big in 1990's fashion?
PCH: Fluorescents
A husband's love?
its like a moon, sometimes more bright, sometimes less and some times neutral.............
What nail color best goes with brown?
A bright, bold turquoise for a splash of color to the neutral brown.
What is the problem when some house lights are bright and others dim?
Check the neutral connections. An open neutral or a high resistance neutral can cause this type of condition. The obvious place to start your search is in the switch boxes that connects to the light fixture.

Bad starter? Bad neutral switch? ignition switch?
How do you fix headlight circuit on 2003 S-10 wdrl and foglights?
foglights work.dr side headlight works on bright but no dim. pass side bright gets dim.
