UPS batteries are typically rated at how many ampere hrs they can supply. IF your 20 Watt device is supplied by 120V then it draws 1/6 amps. (Watts = Amps * Volts for a resistive load). If your UPS were rated for 1 A Hr you could power your device for 6 hours.
You would need at the minimum a 56 KW generator. In reality you would need a 60KW.
Generators are rated in watts or kilowatts. The formula for watts is W = Amps x Volts. To size a generator for the welder the voltage of the machine must be stated.
To answer this question a voltage needs to be stated. The formula needed to find the amperage is I = W/E. Amps = Watts/Voltage. Once the amperage is found, the proper size conductor to handle that current can be established. Without knowing the amperage on 400 watts a good guess would be a #14 wire. This wire size is good up to 1440 watts at 120 volts.
A: It not size but rather capacity. the capacity will be the ac power consumption AC volts X AC current that will get Watts. So the capacity of the inverter should be the same watts plus a safety and efficiency power if the watts is 100 watts i would buy a 125 watts minimum
To determine the size of the breaker needed for a 9,000-watt broiler operating at 220 volts, you can use the formula: Amperage (A) = Watts (W) / Volts (V). In this case, 9,000 W / 220 V = approximately 40.91 A. It's common practice to add a safety margin, so a 50-amp breaker would be appropriate to handle the load safely.
9.5 Kva is the is the same as 9500 watts. Formula for Amps = Watts/Voltage. As you now can see you didn't give me any voltage so that the amperage can be calculated. Without the amps the wire size can not be calculated. Reply in a discussion if you are interested in an answer.
300 watts or less.
It doesn't matter what size bat handle you have just get the right size bat then try the different handles and then pick the one that feels right.
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.
Look on the AC power adapter and read its rating in watts. You will need an inverter with at least that output capacity.
To run a 3HP (horsepower) 120V chainsaw, you would need an inverter that can handle the starting and running wattage. A 3HP motor typically requires around 2,200 to 3,000 watts for starting and about 2,000 watts for continuous operation. Therefore, you should look for an inverter with at least a 3,000-watt output capacity to ensure it can handle both the starting surge and the continuous load. Additionally, it's wise to choose an inverter with a bit of extra capacity for safety and efficiency.
well each type x subwoofer can handle 3000 watts max and 1000 rms (recomended) so about a 2000 watt amp should give u unbelievible bass, if u have 2 alpine type x 12's u need can handle 6000 watts and 2000 rms
