It depends on the voltage of your electrical system. The basic formula is watts = volts X amps. So, if your voltage is 120V then the absolute maximum watts available would be 3600 (30 * 120 = 3600). Note that this is the point at which the breaker would trip, so you could not count on 3600 watts for more than a few minutes. A good rule of thumb is to limit your normal load to 80% of the maximum available. In this case, 80% of 3600W is 2880W. If you put a frozen dinner in the microwave for 5 or 6 minutes and happened to push the watts up to, say, 3500, you would probably get away with it. But try the same trick with the air conditioning that runs for an hour or two and you will trip the breaker. Keep the watts below 80% and you can run forever.

How many watts and romex gauge is safe for a 15amp breaker?
Assuming 120 VAC in a residence maximum watts = 15 x 120 = 1800 Watts. For a continuous load you can support 1440 watts which is 80& of maximum. You need 14 AWG gauge wire.
How many take amp 40 watt fluorescent lamp?
Watts= voltage times amps. So if you divide Watts by voltage, you will get amps = .33333 or about a 1/3 amp load. This is assuming a 120 volt circuit.
How many LED lights can you put on a 20 amp circuit?
The electrical code states that circuit conductors that are fed by this breaker on a continuous load can only be loaded to 80%. Therefore you can have a load of 1,920 watts on this circuit. Assuming you install 8 watt bulbs you can have 240 on this circuit.
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 many watts are equal to 1 hp?
1hp = 745.7 watts
