You obviously do not know what you are doing. Electricity is DANGEROUS and you can kill yourself with it. If something electric in your house needs testing or fixing, employ the services of a qualified electrician to do it for you, DO NOT TRY AND DO IT YOURSELF.

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 much wattage is available in a 15amp breaker?

Wattage (power) is not stored in a breaker; in its tripped position, electrical power form the power line is disconnected. When the breaker is activated, electricity (power) flows through the breaker to the circuit in the home. Using the formula below, you can find the wattage the breaker can handle, not how much it has. Watts = Volts x Amps = 120 volts x 15 amps = 1800 watts A toaster requires 1500 watts of power, so if you are running a coffee maker which probably requires 700 watts or more and turn on you toaster, that 15 amp breaker will trip.


What to do if a plug breaks off in an outlet?

Why does your garbage disposal breaker keep throwing?

There are only two conditions that cause a breaker to trip. An overload condition of the connected load is one cause. To cause an overload condition on a breaker that supplies a garbage disposal, the motor in the unit would have to be jammed. Turn the breaker off and see if you can turn the blades in the unit. This might have to be done from the under side, look for the motors cooling fan on the bottom of the motor and see if you can turn it. If the breaker trips instantaneously when the unit is turned on, then there could be a wire grounding in the motor junction box. Same scenario, turn the breaker off, open the junction box and look for wiring problem. Use your power of smell, it is a fine diagnostic tool when it comes to burnt electrical equipment.

No. Power to all the circuit breakers will be cut off except for the Main power breaker.

There is a thermostat somewhere, usually on the wall or on the heater itself. Just turn the breaker off at the breaker box. Label the breaker if it is not already labeled. Once the power is turned off to the unit, you can disconnect the wires inside the heater to permanantly shut down the unit.
