A #12 cable is rated at 20 amps however only 16 amps can be connected to this cable.

wattage = amperage x voltage

1920 watts = 16 x 120 (each leg)

What happens to the resistance of a circuit when too many outlets are plugged into a 120 V outlet?

As more items are plugged into a circuit the resistance of the circuit rises. This is the same formula that you use for resistances in parallel. As each item is plugged into the circuit its resistance rises causing the current of the circuit to become higher. The breaker is in the circuit to protect the wire from overloading with the higher current . When an over limit of items are plugged in, the breaker trips, cutting off the current to the circuit. A usual limit to a 15 amp circuit is 12 amps or 1440 watts. The breaker will trip at 15 amps or 1800 watts.

Watt how many watts for amps breaker?

Watts is the product of amps times volts. If you are asking how many watts can be put on a 15 amp circuit breaker then 15 x 120 = 1800. This will probably trip the breaker because it is close to the breaker threshold. So lets say 1600 watts.

How many watts can a 20 amp breaker used before it blows the breaker?

A 20 amp breaker on 120 volts will trip the breaker when the total wattage goes over 2,400 watts. But you should never load the circuit more than 80% which would be 1920 watts.

How many watts can a double 30 amp breaker switch handle?

The maximum wattage that a 30 amp breaker can handle is 30 x 230 = 6900 watts. Other variables come into play and this number will decrease depending on the load, duty time, and difference in voltage fluctuation.

How watts for 30 a breaker?

To answer this question the voltage of the circuit from the 30 amp breaker must be given.

Which one has more power the higher the watts or the lower the watts?

Watts are a measure of power, so double the watts and you have double the power.

Is 30 amp double pole breaker ok for 4800 watt wall heater?

Yes. watts / volts = amps. 4800/240=20amps.

How many watts can a 30 amp 120 volt breaker handle?

The connected load in watts to a single pole 30 amp breaker is calculated by the following equation. W = I x E. Watts = Amps x Volts. A higher wattage than what you calculate will trip the breaker.Also another equation you should be familiar with, for breaker sizing if only the wattage is given on the nameplate, is that for amperage from watts. I = W/E. Amps = Watts/ Volts.

How many watts for a 20 amp breaker?


How much 1200 watts on one breaker?

Not a whole lot. Assuming that is 120 volt power, 1200 watts would be 10 amps. A standard breaker is 15 amps.

Can six recessed lights of 50 watts be on a 15 amp breaker?

Should be fine if that is all that is on the breaker.

How many watts can be on a 15amp breaker?

At 120 volts a 15 amp breaker can be loaded to 1800 watts before it will trip. If it is a continuous load then the electrical code states that it is only allowed to be loaded to 80%. This will be 1800 x .8 = 1440 watts. If the voltage is not 120 volts use the following equation Watts = Amps x Volts. Amps being the breaker size that is to be used.

How many appliances can you run from an extension cable at once?

The total load applied to an extension cord is governed by the wire size of the cord. As the extension cord is usually plugged into a wall receptacle. The breaker protecting the receptacle is rated at 15 amps. The total wattage is limited to 15 x 120 volts = 1800 watts. Check the nameplate on the appliances to see what the wattage draw totals. This will give you the answer, any amount that adds up to the total of 1800 watts.

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.

How can you plug 2000 watts 240v into a 120v 20 amp breaker with out replacing your breaker and all the plugs on the line?

You can't.

How much can a 15W circuit breaker handle?

Answer for the US: Breakers are rated in amps, not watts. However, a 15A breaker can handle 15 amps, or about 1800 watts (using 120V), or 3600 watts (using 240V). However, this is only rated for noncontinuous loads (those not lasting for more than three hours). For continuous loads (loads lasting three hours or more), one must derate the circuit breaker by 80%. So for continuous loads, that same breaker should only have 1440 watts (using 120V), or 2880 watts (using 240V) on it.

How many amp breaker is needed for 4000 watts at 220 volts?

The equation that you are looking for is I = W/E. Amps = Watts / Volts.

How many watts will a 60 amp 2pole breaker handle?

Watts = Amps x Volts. 60 x 240 = 14400

If installing several base board heaters with various watts what is the max number of watts you can put on one 20 amp 240v breaker?

For safety reasons ( and the National Electric Code) never put more than 75% load on a breaker, so for you case, 20 amp breaker x 75% = 15 amps 15 amps x 240 volts = 3600 watts 3600 watts

How many watts can a 15 amp breaker hold?


How many watts can a 30 amp breaker support?

At 240V it can support 7200W

Can a 15 amp breaker hold 300 watts at 120 volts?

Yes, it can.

How many amps circuit breaker is required for 1400 watts?

To answer this question a voltage needs to be stated. I = W/E, Amps = Watts/Volts.

How many watts can a 20 amp breaker hold?

Multiply the voltage by the amps. So on a 240 v supply it would be 4800 watts.

How many watts will a 14 gauge extension cord handle?

Assuming that the extension cord is plugged into a normal household receptacle rated at 15 amps the cord will handle 15A x 120V = 1800 watts. If the cord is of any length, at that wattage, you will feel the cord start to get warm like a heating cable.
