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.

∙ 8y agoThe 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.

What is the wire size required for 1800 watts for lamps?
14 gauge will handle it with a 15 amp breaker. If you use 12 gauge use a 20 amp breaker.
Can you use 14 wire for a light off a 20 amp circuit?
Yes, in home wiring as long as it is protected by a 15 amp breaker. Remember this circuit will only handle 1800 watts and cannot be loaded to any more than 1440 watts. So if each light is 75 watts then the maximum you can install is 19.
Should a hot water heater be put on a 30 single or 30 double amp breaker?
What governs the type of breaker is the voltage and wattage of the heater elements. If the tank is 120V then you would only use one breaker. The size of the breaker you use will depend on the watts of the element. Watts = amps x volts, Amps = Watts/ volts. Once you establish the amperage then size the wire and the breaker to fit. If the tank is 240V the same rules apply only you would use a 2 pole breaker. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
Will 20 amps handle 3500 watts?
No. 20 amps at 120 volts will handle a maximum of 2400 watts. And you should never continuously load a 20 amp 120 volt circuit to no more than 1920 watts.
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.
How many watts can a 20 amp breaker handle per hour?
A 20 amp breaker can handle up to 2400 watts per hour (20 amps x 120 volts = 2400 watts).
How many watts will a 60 amp 2pole breaker handle?
A 60 amp 2-pole breaker can handle up to 14,400 watts (60 amps x 240 volts). This is because a 2-pole breaker provides 240 volts, which is the typical voltage for larger appliances and machinery.
How many watts will a 30 amp two pole breaker handle at 240 volts?
30X240=7200
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.
What size double dimmer switch do you need for 6 x 40 watt halogen bulbs?
A double dimmer switch that can handle a total load of 480 watts would be suitable for 6 x 40 watt halogen bulbs. This means each dimmer switch should have a minimum rating of 240 watts to accommodate the 6 bulbs collectively.
What is the wire size required for 1800 watts for lamps?
14 gauge will handle it with a 15 amp breaker. If you use 12 gauge use a 20 amp breaker.
How much wattage is available in a 15amp breaker?
A 15-amp breaker can handle a maximum load of 1800 watts (15 amps x 120 volts). However, it is recommended to only load a circuit up to 80% of its capacity, so in practice, you should only use up to 1440 watts on a 15-amp breaker.
How many watts will a 20 amp douple pole breaker handle?
The formulae for calculating watts to amps is Watts divided by Voltage. Therefore to get from Amps to Watts the calculation is Amps × Voltage. Therefore if you are working on a 240 volt supply the calculation is 20 (Amps) × 240 (Volts) which = 4800 watts.
If you have a 30 amp breaker how many watts can it use?
To answer this question a voltage must be given. Watts = Amps x Volts. <<>> Answer At 115 volts ac, 30 amps equals 3,450 watts.
Why will too many electrical devices operating at one time after blow a fuse or trip a circuit breaker?
The load exceeds the limit of the breaker or fuse. For example a 20 amp breaker on a 120 volt circuit will handle 2400 watts. Exceed that wattage and the breaker will trip or the fuse will blow.
What are five light floor lamps?
Lamps with five flexable lights that provide great lighting and come with shades and four way switches. The information below is telling you how brite the light will be if you used the same number watts in the lamp. Using 15 watt bulbs Using 30 watt bulbs Using 40 watt bulbs Using 60 watt bulb Switch 1: 30 watts Switch 1: 60 watts Switch 1: 80 watts Switch 1: 120 watts Switch 2: 45 watts Switch 2: 90 watts Switch 2: 120 watts Switch 2: 180 watts Switch 3: 75 watts Switch 3: 150 watts Switch 3: 200 watts Switch 3: 300 watts Switch 4: 0 watts Switch 4: 0 watts Switch 4: 0 watts Switch 4: 0 watts
How many watts can be put on a 20 amp 208 volt circuit breaker?
A 20 amp circuit breaker at 208 volts can handle up to 4160 watts (20 amps x 208 volts = 4160 watts). This is calculated by multiplying the amperage by the voltage to determine the maximum wattage capacity of the circuit.
