Ok, lets assume that these are not newly installed lights or lights added to this already existing circuit first what type of lights are they? the reason I asked is because if they are fluorescent lights it could be a faulty ballast. if it's regular light bulbs then they are several things to look for. how many lights on this breaker? have you placed a higher wattage bulb in these lights than recommended? what is your combined wattage? a 15 amp breaker is rated to supply power safely up to a maximum of 1440 watts. add up the wattage of each light bulb including any outside flood lights or outlets also on this circuit. If the the total is under 1440 watts then first replace the breaker with the same wattage rating then turn each light one at a time and wait to see if the breaker trips again. If it does, check the last light you switched on. Answer for USA: Never load a breaker to its full rating. The law allows only 80 percent of the breaker rating. That's the 1440 watts for a 15 amp breaker, and 1920 watts for a 20 amp breaker. Also look for a load you might not think is on the breaker, such as an outdoor light, or something in a hall or another room. Other causes: - A motor draws more current when it starts than when it runs. - An aging breaker, or one that has been overloaded too many times, can trip at a reduced current. If this is the case, it needs to be replaced.

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work

AND

always use an electricians test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized.

Why do some lights go off in your house when you turn on too many appliances?

In a well designed house the lights are not connected to the same circuit as an appliance. If by going out you are saying that a breaker trips, then your appliances and lights combined are exceeding the rating of the breaker. You either need to rewire and balance the loads better or plug high current appliances into different outlets on another breaker. If you are not tripping breakers, but lights are just dimming you have a bigger problem with inadequate current supplying your house.


Parking lights will not turn off is it a relay or circuit breaker?

This issue could be caused by a malfunctioning relay that fails to disengage when the parking lights are turned off. It's also possible that there could be a problem with the switch controlling the parking lights. Checking these components would be a good place to start troubleshooting the issue.


How do you replace a 15 amp breaker in the circuit box?

The breaker will have a black wire connected to it. Turn off the main breaker and then disconnect that black wire from the breaker. The breaker will snap into the main bar. Remove the breaker and install the new one. Reconnect the black wire to the breaker and then install the cover and turn the main breaker back on.


When a home circuit breaker opens the lights in some rooms go off but the lights in some rooms stay on. Explain why.?

The circuit breakers in a panelboard feed separate circuits. The lights that stay on are on a different circuit than the ones that go off. To fine the circuit that feeds the lights that stay on, go to the panelboard and turn off the breakers one by one until the lights go out. This is the circuit that feeds that circuit of lights. Remember that lights and receptacles can be on the same circuit together.


What can you do if your lights won't turn on and you've already replaced the light switch?

If the lights still won't turn on after replacing the light switch, check the circuit breaker to ensure it hasn't tripped. You can also inspect the wiring for any loose connections or faults. If these steps don't solve the issue, it may be best to consult a professional electrician to diagnose and fix the problem safely.

Why won't the lights turn on after flipping the breaker?

If the lights won't turn on after flipping the breaker, it could be due to a blown fuse, a tripped circuit breaker, a faulty light switch, or a wiring issue. It is recommended to check these components and consult a professional electrician if needed.

Would you be able to run sixteen TVs and sixteen games consoles in my house I am worried my house won't be able to cater for these due to a lack of electricity or maybe it blows the power HELP?

It depends on how big the breaker box is for your house, in my old house i couldnt have all the lights on at once because it would blow a fuse and i would have to go outside and mess with the breaker box. considering its 16 tvs AND game systems i would say unless you are rich and have a HUGE HUGE house with a breaker box made for a hospital then most likely you will blow a fuse when attempting to turn them all on. Its not the smartest choice. When you blow a fuse all or most of your lights will go out and unless you know where your breaker box is and how to fix it then i dont recommend you trying that much at one time.


Are the lights and outlets in this room connected to the same circuit?

To determine if the lights and outlets in a room are connected to the same circuit, you can check the circuit breaker panel. If the lights and outlets are on the same circuit, flipping the breaker for that circuit will turn off both the lights and outlets. If they are on separate circuits, turning off the breaker for the lights will only affect the lights, and the outlets will still have power.


When do you turn off all the lights in your house?

How do you find a short in an 97 Nissan Sentra that blows the fuse for the tail lights and dash lights when you turn the lights on?

Try removing bulbs from all exterior lights turn switch on to see if fuse blows--if not replace one bulb at a time to determine where problem is. If fuse blows without bulbs could very well be switch "dead shorted" to ground IM HAVING THE SAME PROBLEM SO IF YOU FIGURE IT OUT PLEASE LET ME KNOW AT GODLIVERKILLA@YAHOO.COM A mechanic told me that the switch that is on the column is usually the problem. Cost about 70.00 . Raygracik@msn.com


On your 1985 Toyota pickup the fuse blows out when you turn on the lights the head lights stay on but not the rear lights?

Check wiring and sockets for dead short to ground at: Parking/Tail and dash lights Remove all bulbs and sockets -replace 1 at a time until fuse blows Investigate that socket Check wiring and sockets for dead short to ground at: Parking/Tail and dash lights Remove all bulbs and sockets -replace 1 at a time until fuse blows Investigate that socket


How can I reset outdoor sensor lights?

To reset outdoor sensor lights, first turn off the power to the lights at the circuit breaker. Wait for a few minutes, then turn the power back on. This should reset the lights and they should start working again. If the issue persists, consult the manufacturer's instructions or contact a professional for assistance.
