It depends on the voltage. Divide watts by volts to get amperes.

So far i didn't get watts on my compressor explaning LRA-does not help ! becouse don't have number to multiply by 220 V in order to get replacement supplyer need watts !

RLA= Rated load amps or running loads amps depending on mfg.
FLA= Full load amps
LRA= Locked rotor amps.
watts is voltage times current, So use 220 time the LRA get that watts or 220 times FLA to get that watts and
multiply 220 times RLA to get watts.

What can i run with a 500 watt stanley converter

Assuming the output is 120VAC, you can only run items pulling about 4 amps. If the voltage output is 220 VAC, you can only run items pulling about 2.25 amps. Read the labels on the devices you want to use, they should list either watts or amps used.

To convert amps to watts: Current times voltage
To convert watts to amps: Watts divided by voltage

How many 5 watt outside lights can you power with a 20 amp breaker?

Volts x amps= watts.
20 amp breaker x 125 volts = 2500 watts.
However, electrician use the 80% rule, so multiply 2500 x 80% = 2000 watts.
So if you have 20 amp breaker, and 12 gauge wire, and 20 amp switch, and distance is less than 150 feet, then watt load is 2000 watts or 400 5-watt bulbs.
Keep in mind that most switches are 15 amp, and not 20 amp.
Recalculate for 15 amp switch = 1875 watts x 80% = 1500 watts or 300 5-watt bulbs.

I need to know what the power consumption is for my serger as we will be moving off the grid. thank you.

Hi gladysmorin...
We would need the info from your metal tag on the surger motor before we can tell you what the power consumption would be.
So you will need to look on the metal tag that is attached to the surger motor and retrieve that information, you will need the amperage and the voltage.
But you can also figure out how many watts any appliance will consume in will do some math.

If you want the watts,volts or amps for a given appliance follow the examples below:

Amps X Volts = Watts
example: 3.0 amps X 220 volts = 660 Watts
Watts ( / ) divided by Amps = Volts
example: 100 watts ( / ) divided by10 Amps = 10 Volts
Watts ( / )divided by Volts = Amps
example: 60 watts ( / ) divided by 120 volts = .5 Amps
( / ) = the right slash means...divided by.

Given 1hp motor how to compute the exact amount of amphere use in circuit breaker

You're not going to be able to do this with just a known Horse Power.

There are 3 elements to the equation, with any two, you can work out the third.

If you want to know how the amperage, you will need to know the voltage and wattage of the motor. I imagine that you already know the voltage (It's going to be 220V or 110 volt)

Watts divided by volts = Amps


A 220v 1000 watt motor (1000 divided by 220) will draw 4.55 amps
A 110v 800 watt motor (800 divided by 110) will draw 7.27 amps

Bear in mind that most washing machines have a couple of windings for wash and spin. As an average, the was winding will usually be about 500 watts to spin and about 250 watts to wash. ALSO, bear in mind that if you are using this data for a WASHING MACHINE, then there is a water heating element in there too and that draws about 2Kw (2000 watts)

Dont just take this as read, you DO need to check wattages, but, working on what I have just said, the max consumption on a 220V machine will look like this:

At Spin, with a 500 Watt consumption: (500/220) = 2.3 amps
While Washing with a 250 watt consumption: (250/220) = 1.14 amps

Consider that the WASH and HEAT may be running at the same time.
2Kw heating (2000/220) = 9.1 amps PLUS 1.14 amps for the motor - Total wattage 10.24 amps

Watts / Volts = Amps
Amps x Volts = Watts
Watts divided by amps = Volts

I have a trailer house that has a 100 amp breaker box in it. I has gas for heat, water heater and stove. I am changing them to electric. Will I need to change the panel put to a 200 amp.

Its probably not a bad idea. Thats alot for a 100A panel to handle, a range needs a 50A, a water heater needs 30A, and the heat will need a 50A or a 60A breaker... Plus whatever else is in the house will be a bit more than the 100A service can handle. But if you don't have the money it will do for a while because for the most part they won't all be pulling at the same time. Word to the wise get at least a 30 space panel when you upgrade, I always install a 40 space panel because for the cost difference its well worth it for future needs because you'll fill it up quicker than you think and you'll have space for anything else you may want to add later on. Hope I helped

Purchased "Reliance Lowboy electric water heater"

The water heater has two 4500 watt elements.
However both elements are not turned-ON at same time
So the water heater is 4500 Watts

Volts x Amps = watts
Amps =watts divided by volts
Amps = 4500 Watts divided by 240 Volts
Amps= 18.75

So that says a 20 amp breaker ... except for the 80% rule
80% rules says for safety, your Amp rating should be multiplied by 80%

20 amp breaker X 80% = 16 amps
20 amp breaker is actually safe for just 16 amps, and your water heater draws 18.75 amps.

The calculation shows you need a 30 Amp breaker.
30 Amp breaker requires 10 gauge wire.

I have a behringer 1500 watts amp that is clipping

What is happening is that your amp can deliver 1500 Watts at a given impedance. The Sub PROBABLY is a higher impedance. Your amp runs out of voltage due to the speaker impedance, hence it "flat tops" or clips.

You will probably find the sub is 8 ohms and your amp might deliver 1500 Watts on a 2 ohm system (this is "specsmanship" to sell their product... more is better thing...

If your amp was as above, the max voltage output would be the same before clipping but with the resistance 4 times, the current is only one fourth that which would deliver 1500 Watts. So you would only get 1500/4 Watts into the speaker or about 375 Watts.

Need to hook up to a 4000 watt amp

Why would you hook up 4000 watt amp to a speaker that has only 1000 watts. Try a 800 watt amp instead unless you just dont want the spealers.

Inverter problem

If you got the store bought APC 350 UPS, you most likely overloaded them, and killed them beyound repair.

People should never buy a 350VA. They are way to small for power supplies most of us now have. you need to start out to 1000VA plus you need to do the math to figure out how big of a UPS you actually need in the show room.
What am I talking about? What is the significant, or the math of what I am saying here. 115V x 1 amps = 115VA x .778 power factor = 89.47 watts Start up 50 watts = 39.47 watts
115V x 2 amps = 230VA x .778 power factor = 178.94 watts Start up 50 watts = 128.94 watts
115V x 3 amps = 345VA x .778 power factor = 268.41 watts Start up 50 watts = 218.41 watts
115V x 4 amps = 460VA x .778 power factor = 357.88 watts Start up 50 watts = 307.88 watts
115V x 5 amps = 575VA x .778 power factor = 447.35 watts Start up 50 watts = 397.35 watts
115V x 6 amps = 690VA x .778 power factor = 536.82 watts Start up 50 watts = 486.82 watts
115V x 7 amps = 805VA x .778 power factor = 626.29 watts Start up 50 watts = 576.29 watts
115V x 8 amps = 920VA x .778 power factor = 717.76 watts Start up 50 watts = 667.76 watts
115V x 9 amps = 1035VA x .778 power factor = 805.23 watts Start up 50 watts = 755.23 watts
115V x 10 amps = 1150VA x .778 power factor = 894.70 watts Start up 50 watts = 844.70 watts
115V x 11 amps = 1265VA x .778 power factor = 984.17 watts Start up 50 watts = 934.17 watts
115V x 12 amps = 1380VA x .778 power factor = 1073.63 watts Start up 50 watts = 1023.63 watts
115V x 13 amps = 1495VA x .778 power factor = 1163.11 watts Start up 50 watts = 1113.11 watts
115V x 14 amps = 1610VA x .778 power factor = 1252.58 watts Start up 50 watts = 1202.58 watts
115V x 15 amps = 1725VA x .778 power factor = 1342.05 watts Start up 50 watts = 1292.05 watts
115V x 16 amps = 1840VA x .778 power factor = 1431.52 watts Start up 50 watts = 1387.52 watts
115V x 17 amps = 1955VA x .778 power factor = 1520.99 watts Start up 50 watts = 1470.99 watts
115V x 18 amps = 2070VA x .778 power factor = 1610.46 watts Start up 50 watts = 1560.46 watts
115V x 19 amps = 2185VA x .778 power factor = 1699.93 watts Start up 50 watts = 1649.93 watts
115V x 20 amps = 2300VA x .778 power factor = 1789.40 watts Start up 50 watts = 1739.40 watts
