If you mean 220 single phase as in two hots and a neutral 110V-0-110V (in the US this would be 240V 120V-0-120V), then the answer is most 3-phase meters cannot be used. A few meters can be setup for either configuration, check the manual for the specific one you want to use. If you mean 220V single phase with just one hot wire and a neutral, then a larger percentage of 3-phase meters can be used, and will meter accurately. But again, the meter has have this as one of the setup choices. Check the manual. One possibility would be if you have a meter that can be setup to use 3 CT's and tell it that it is hooked to a wye system with neutral. If it sees current on just one phase to neutral, this is a valid condition, since the system could be feeding unbalanced loads (remember the meter thinks this is a 3-phase system). This would only work if the meters wiring diagram calls for CT's on all 3 phases. Many meters call for only two CT's, calculating the 3rd leg by using the two known values. This type of setup would not meter accurately for your single phase, I believe. And this will not work on a 110V-0-110V system, because a 3-phase meter expects 120 degrees between phases, not 180. Oh, I didn't mention the case where you might have two hots and no neutral. The 3-phase meter would have to be set up for a delta connection as far as the meter was concerned, since there is no neutral. It could work, not sure on this one.
Yes, three-phase meters are designed to work even if the phases are unbalanced, which can actually happen if only single-phase loads, such as lighting, are on.
Resistors are rated in wattage so the lowest wattage rating will be the wattage of the series circuit. It will be able to handle that power any more and the lowest wattage resistor could be damaged and fail.Another AnswerWhen two or more resistors are connected in series, the resistor with the lowest resistance will operate at the highest power. If the power developed by a resistor exceeds its rated power, then the resistor may burn out.
A dimmer switch is used for lighting loads and not heating loads. The wattage rating on a dimmer switch is what the manufacturer recommends as the maximum load that the switch can handle. For example if you have ten 100 watt lamps, the total load wattage would be 1000 watts (10 x 100). Too much load for a 600 watt rated dimmer switch but not for a 1000 Watt rated dimmer switch. So you can see that the rating on a dimmer switch governs the maximum wattage load that can be connected in the circuit that is to be controlled.
When it comes to tightening bolts, there is a specific measure for bolts. You need to go through the manual. There is a spring laid in the handle as when the wrench reaches the particular limit, that could bend proportionally. Thus, the worker should stop when it reaches the particular limit.
Usually nobody is willing or able to do this, but the only way to accurately check a tanks "fullness" level is to measure the solids. It is easier to calculate how often the tank should be pumped based upon the size of the tank and usage. There is a useful chart on my website hunnywagon.com that will help you determine if it's time to pump. Most households fit into the "every 3 years" category. Okay, getting back to the messy way... The baffles in the tank that allow for proper functionality are only tall enough to safely handle 6 to 8 inches of floating solids before particulates begin washing out into the leach field. On the bottom of the tank, there is also a layer of solids that build up over time. These are a bit more difficult to measure. When they rise to a level approaching the bottom of the baffle, particulates will also be washed out. It is common for these two solid layers to be different in thickness so don't assume the bottom is the same as the top. Professionals will sometimes use a special tool that removes a sample in a clear tube to accurately measure solid contents. http://hunnywagon.com
A 3-phase meter measures the sum of the power in the three phases, so if power is drawn on one phase only it will still be correctly measured.
It depends on the scale, but most scales accurately measure somewhere between 300 and 400 pounds. The really cheap ($10) scale will measure closer to 300 pounds accurately, while scales running around $25 will measure accurately to about 400 pounds.
it can't handle more power than that rated wattage. exceed the rating and it burns out.
The solo x is a bad subwoofer it can handle a lot of wattage and will break windows. JLs is a good sounding sub but probably cant handle as much wattage as the solo x
Yes, however, the RPM will increase by 20%, if the motor is connected to a shaft or driving something that can not handle the torque, then you might run to heating issues or performance issues.
Your question is asking about two entirely different things. The size and the wattage it is able to handle have nothing to do with each other except for the generalization that larger subwoofers can handle more wattage than smaller subwoofers.
Look on the label of the fixture ,it will tell you the maximum wattage the fixture will safely handle.
Well mostly it depends on the peak wattage of your stereo, if you have a higher wattage stereo I would go with speakers that could handle your stereos watts or they will distort.
You need to find the wattage of the pump motor. This is found by multiplying the voltage of the motor by the amperage of the motor. Once you have this figure use it to find an inverter that can handle this wattage load at a 240 volt output.
