either a bad fixture or a loose connection. if its a light fixture first check the obvious - replace bulb with a known good one. next turn off switch and remove fixture exposing the wiring. remove wire nuts and put a volt meter across the black and white wires [dont let them touch!!!]. if you dont have a meter use a lamp or radio and fasten the plug to the wires being very careful to keeping them from touching. place something non conducting between the prongs after connecting the wires to the plug and then and only then turn the switch on. you should get juice to the temporary appliance. if so replace the fixture with a new one. if its just a lighting fixture usually all it is is a bad switch. take it apart and take it to Home Depot or lowes which usually will exact replacement parts. always remember to keep switch or better yet the breaker off while having any wires exposed and turn on breaker only after wire nuts securely in place and hands out of harms way. lots of luck.
The light is wired the same as any voltage fixture. Bring the source voltage to the fixture and connect it to the two fixture wires. If you want to control the off-on of the fixture take the source voltage to a switch first and then out of the switch to the light fixture.
Bad switch or a short and tripped the breaker.
shut off the power to the box, switch out the breaker and resture the power
On the "hot"wire that comes from the breaker panel the voltage should be from 115 to 120 volts. This is taken from the "hot" wire to either the neutral or the ground wire. If its not then you have a breaker problem or you are on the wrong scale of the test meter.
Shut off the breaker that supplies the voltage to the fluorescent fixture. Wire the new pull chain switch in series with the black incoming wire and the black wire of the ballast. Turn the breaker back on and your switch will now control the off on operation of the light fixture.
Yes you can. The proper wiring of a switch is to bring the hot wire to the top of the switch terminal and connect the load to the bottom of the switch. When the breaker is turned off it disconnects the voltage from the top of the switch and the switch is then safe to work on. By not turning the breaker off, the voltage is present at the top of the switch which could subject you to a nasty shock if you come into contact with it.
Please clarify what you mean by low voltage light fixture. What voltage?
You have checked the wire at the switch? Breaker may be bad but not tripped. Loose connection at light or outlet that the switch controls. Use a screwdriver to touch the two terminals on the switch if you do not have a tester. May not be hot side of the circuit, but the neutral.
Blown fuse or tripped breaker. Replace the fuse or reset the breaker.
I have seen cases where an open breaker is the cause of such problems. It appears to be on, but is open internally. Check the voltage with a meter or temporarily piggy-back the fan circuit on another breaker. If it isn't the breaker it is a connection somewhere in the circuit leading to the fan switch. If the power is coming from a GFCI outlet, check that. Otherwise, you start at the breaker measuring voltage and then try and find other spots in the circuit before the fan switch and check voltages there. You can also go a bit high tech and buy a signal tracer for about $30 and check out the circuit wiring. Then there is always an electrician who will likely find the problem quickly.
form you question i found out that your circuit bearker panal has burn too ,,in case not to happne again you please have got to check the AMPS at both ,,the bulb and the hell circuit breaker ,,the buy the high of AMPS for ur circit breaker .
Check for the obvious, circuit breaker , emergency switch or thermostat off, fuel valve closed, tripped safety switch ( reset it once and determine reason it tripped and repair) Call for service if none of these gets you going.
