For a 30-amp breaker at 220 volts, you typically need to use 10 AWG (American Wire Gauge) copper wire. If you're using aluminum wire, you should opt for 8 AWG. It's important to ensure that the wire insulation is rated for the appropriate temperature and application, and always adhere to local electrical codes and regulations.

What size amp breaker you need for a ac and a heater unit?
The sizing of a breaker is dependant upon the size of the wire it protects. The size of the wire is dependant upon what the load current in amps is. Without the amperage and wattage and the voltage of the appliances an answer can not be given. W = A x V, Amps = Watts/ Volts.
What size breaker for a 1500 watt 120 volt heater?
To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.
How do you calculate amp of circuit breaker to use on a 4800w oven?
Ovens typically run at 240 volts which will be a two pole breaker in your panel. Watts = volts x amps. 4800 / 240 = 20 amps. If by chance you are using 120 volts then double it to 40 amps. All wiring must conform to size of breaker used.
What size breaker for a 6000 watt 240 volt oven?
To determine the appropriate breaker size for a 6000-watt oven operating at 240 volts, you first calculate the amperage using the formula: Amps = Watts / Volts. This gives you 6000 watts ÷ 240 volts = 25 amps. According to the National Electrical Code (NEC), it's advisable to use a breaker rated at 125% of the continuous load, so a 30-amp breaker would be appropriate for this oven.
How many amps needed for a 3000 watt 240 volt base board 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 breaker do you need for 5.7kw neff oven?
A breaker is sized by the wire size. The wire is sized by the amperage. The formula for amperage is I = W/E. Amps = Watts/Volts. As you can see with no voltage stated an answer can not be given.
What size amp breaker you need for a ac and a heater unit?

What size breaker for a 1500 watt 120 volt heater?
To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.
If you have a circuit breaker box containing 650 amps of circuit breakers it is 3 phase 480 volts what size kva generator do you need?
The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.
How do you calculate amp of circuit breaker to use on a 4800w oven?
Ovens typically run at 240 volts which will be a two pole breaker in your panel. Watts = volts x amps. 4800 / 240 = 20 amps. If by chance you are using 120 volts then double it to 40 amps. All wiring must conform to size of breaker used.
What size amp circuit breaker would protect a 12kW boiler?
The breaker protects the wiring not the boiler. 12,000 watts at 240 volts will require 50 amps. So, you will need a 60 amp breaker using AWG# 6 wire on a dedicated circuit.
What size breaker you would use for a 110 volt window air conditioning unit?
Breaker sizing is dependant on what the load amperage is that the breaker is connected to. If the amperage is not given but just the wattage, use this equation I = W/E. Amps = Watts/Volts. This air conditioner unit should be on a dedicated circuit receptacle. On these types of loads the conductor can only be loaded to 80% of the conductors rating. So a 15 amp breaker times 80% = 12 amps or Watts = Amps x Volts, 12 x 120 = 1440 watts. A 20 amp breaker times 80% = 16 amps or Watts = Amps x Volts, 16 x 120 = 1920. Once the breaker is sized remember to use the correct wire size to correspond with the amperage of the breaker.
What size breaker should be used for a 3.6 kW oven?
3000 / 240 = Amps. You de-rate a breaker by 20 % for continuous load like an oven. You could get by with a 20 Amp breaker and 12 AWG wire. However, I would recommend 30 Amps and 10 AWG for an oven for the long run.
What amp breaker do you need for a 325 watt heater 120 VAC?
Electrical breakers are sized by the conductor that is connected to it. The conductor is sized by the current that is drawn by the circuit. The formula for amperage is I = W/E. Amps + Watts/Volts. 325/120 = 2.7 amps. A #14 copper conductor is rated at 15 amps. This is the minimum size wiring that is used for house circuits loads. The breaker for this size wiring will be a 15 amp breaker.
How many amps needed for a 3000 watt 240 volt base board 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.
Size of breaker for 5.4 kilowatt stove?
The sizing of a breaker is based on the amperage that the device draws. To obtain the amperage from kilowatts a voltage must be stated. Amps = Watts/Volts. The following values are based on the stove using a supply voltage of 240 volts. Amps = 5400/240 = 22.5 amps. The breaker required for this stove will have a 30 amp rating. The feeder supplying the voltage to the stove will be a #10 AWG.
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.
