Why would a breaker trip after 30 sec with nothing plugged in to the circuit except the tv that is turned off?
First unplug the TV. Some TVs may still draw current when off, but not enough to cause a breaker to trip. However you still want to make sure you don't fry your TV as you troubleshoot. If there is nothing plugged in to any outlet on the branch circuit and there are no light fixtures the problem is a bad breaker or in the wiring. The ideal is to have an electrician troubleshoot since you can kill yourself while messing with the breaker panel if you don't know what you are doing. Turn breaker off, make sure with a meter that the breaker is no longer hot and remove the wire by unscrewing the lug screw. Do the same for another breaker of the same rating. Hook the first wire removed to the second breaker. Turn on the second breaker. If it doesn't trip the problem is first breaker, and you need to replace it. If the second breaker trips it is the wiring. With the second wire and breaker restored to original connection, leave the first wire disconnected. Measure the resistance with a meter of the disconnected first wire to neutral which are where white wires are connected in panel. If you have everything unplugged there should be an open circuit. If not you need to start disconnecting wires in outlets and fixtures on the branch circuit and determine where the short is. Since breaker stays on for 30 seconds it is likely the breaker since a dead short would trip breaker immediately. The exception would be a short that is causing a current to flow that is very close to the rating of the breaker. If the breaker is good then I suspect you have something plugged in you don't know about.
Why power circuits and lighting circuits require a separate circuit breaker?
Utility outlets and lighting outlets should be separate so that when a utilization device plugged into an outlet trips the breaker or blows the fuse, you won't be left trying to find your way to safety in the dark. Light fixtures are much less likely to trip a breaker in ordinary use, but there are places you also want more than one lighting circuit for illumination.
A GFCI device in a breaker is intended to?
A GFCI device in a breaker is intended to trip the breaker open when a ground fault is sensed in the circuit that the breaker is protecting.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
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.
How many 250 watt 240vachigh pressure sodium fixtures can you install on a house service with a twenty amp breaker?
My calculation shows 15 such fixtures on that circuit.
New shop 20 amp circuit 32 amp fixture how many fixtures can be put on circuit?
A 32 amp fixture can not be fed from a 20 amp breaker as the breaker will trip every time.
How do you covert 277 light fixtures to 110 light fixtures?
You need to rewire to a lower voltage at panel or get a transformer that steps down 277 to 110 volts. Make sure wire is sized for new load as well as breaker.
How to wire a bedroom for electrical outlets and lighting fixtures?
To wire a bedroom for electrical outlets and lighting fixtures, you will need to plan the layout, install a circuit breaker panel, run wires from the panel to outlets and fixtures, connect the wires to the outlets and fixtures, and test the connections to ensure they are working properly. It is recommended to hire a licensed electrician for this task to ensure safety and compliance with building codes.
You have 6 1000 watt HID light fixtures in your greenhouse you can only run one at a time or the breaker trips you need to run all six at once what should you do?
You'll need to rewire it. 6000W at 120V is 50A. Even if you can find a 50A breaker, it's almost certainly a code violation (and a safety hazard) to simply replace the breaker without also rewiring to use a heavier gauge wire. It would be much better to break the wiring out into say 3 20A circuits with two 1000W bulbs on each circuit.
How can I safely add a circuit to a breaker box in my home?
To safely add a circuit to a breaker box in your home, follow these steps: Turn off the main power supply to the breaker box. Identify an available slot in the breaker box for the new circuit. Install a new circuit breaker in the empty slot. Run the new wiring from the breaker box to the desired location. Connect the wiring to the new circuit breaker and the electrical outlets or fixtures. Test the new circuit to ensure it is working properly. If you are unsure or uncomfortable with any step, consult a licensed electrician for assistance.

Can you put two fixture on a single pole 15 amp breaker?
Yes, as long as your fixtures don't require more than 1650-watts in an 110-volt supply.ACTUALLY:You should never exceed 80% of the capacity of a breaker. If you actually used the 1650 Watts the breaker would trip because it would have reached the maximum capacity. Make certain that the maximum current draw on any circuit does not exceed that 80% limit.

Why would the two light fixtures and one overhead fan in your bathroom all go dead at once and remain dead even though the breaker has not tripped?
Proably due to a GFCI breaker located in an outlet either in the bathroom or on the same circuit, possibly in another room like the kitchen or other bathroom. You will see the button on the outlet....
