A 900 watt microwave will live quite comfortably on an ordinary (US) 20 amp circuit breaker supplying multiple 15 amp receptacles. A 20 amp breaker can support up to 2400 watt load, while a 15 amp typical receptacle can support a maximum 1800 watt load.

What size of electrical wire needed for 100A circuit breaker?
#2 copper
What breaker size does a 1000w microwave need?
A 1000 watt microwave at 120 volts draws 8.3 amps. Make the circuit a dedicated circuit, use a 15 amp breaker and a #14 copper conductor which is rated at 15 amps to complete the circuit path.
How many amps breaker is needed for a 400 watt heater?
A 400 watt heater can safely be used on a 15 amp circuit. The size breaker needed for a circuit is determined by the size of the wiring in that circuit. AWG #14 wire requires a 15 amp breaker. AWG # 12 wire requires a 20 amp breaker.
What size circuit breaker is needed for a 300 watt bulb?
A 15 amp circuit breaker will handle this situation very well. The smallest home breaker is rated at 15 amp.
What is the maximum wire size needed for a typical branch circuit that is protected with a 20-amp circuit breaker?
I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.

What size breaker is needed for a 1100 watt microwave?
A minimum of 15-amp breaker is "needed", but a 20-amp is often required by electrical code for that situation.
How many amps breaker is needed for a 400 watt heater?
A 400 watt heater can safely be used on a 15 amp circuit. The size breaker needed for a circuit is determined by the size of the wiring in that circuit. AWG #14 wire requires a 15 amp breaker. AWG # 12 wire requires a 20 amp breaker.

What size circuit breaker is needed for a 90 amp spot welder?
AWG #4 copper.
Is 15 amp circuit breaker big enough for 1100 watt microwave?
Yes, at 120 volts the circuit can be legally loaded up to 1440 watts. The minimum wire size for a 15 amp breaker is a #14 copper conductor. A microwave oven should be on a dedicated circuit meaning that this device is the only one using this circuit.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
The wire!! The breaker is there to protect the wiring not the device plugged into the circuit.
What size circuit breaker is needed for a 1100 watt microwave?
That will draw about 9 amps at 120V. A 15 amp breaker if the circuit conductor is #14 or 20 amp breaker if the circuit conductor is #12. 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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What size amp circuit breaker should be used for a home entertainment system?
You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
Installing a 120volt appliance what breaker is needed at the electric box?
Need to know what the wattage or the amperage is of the appliance. The load amperage is what governs the wire size and the breaker to protect the circuit.
