What do you consider high? If the voltage is between 115- 125 volts, it's fine.

    No lights upstaires circuit breaker keeps tripping


    Jan 2013
    1) Move wire to another same-size circuit breaker to eliminate bad circuit breaker as suspect.
    Do NOT increase size of breaker or it will cause fire.
    http://waterheatertimer.org/How-to-replace-circuit-breaker.html
    http://waterheatertimer.org/Troubleshoot-household-electricity.html

    2) Put hand on each appliance and outlet to see which ones are warm. Outlet should never be warm or hot. Replace outlet. Inspect wires for loose and burned connections.

    3) If the breaker is good, then add up total watts being used by checking watt rating on each device. 100 watt light bulb is 100 watts. Big screen TV has a label that shows 300 to 500 watts. Computer has label. Space heater has label showing 1500 watts. Iron has a watt rating label. Take total watts and divide by 110Volts and this will give amp load. Total watts used = 2000 and then divide 2000 by 110 volts = 18.8 amps
    Compare amp load with circuit breaker.
    20 amp circuit breaker has 80% safe maximum, or 16 amps.
    If amp load is 18.8 amps, then 20 amp breaker is starting to get hot, and weak breaker will start tripping.
    If amp load is 18.8 amps, and breaker is 15 amps, then you are overloaded and breaker is feeling the heat, and tripping because of heat.
    Solution is to reduce amp load.

    4) If you have short circuit, that can also trip breaker.
    Unplug everything and then plug things back in slowly to see which plug or appliance is causing the problem.

    Honda eu3000is generator surges


    Inverter Generator Benefits
    • The EU3000 series generators are inverter generators. The generator features an alternator, which produced high-voltage, multi-phase AC power. This power is converted to DC power and then converted back to AC. This process is controlled by a microprocessor and is necessary to provide stable, consistent power capable of running equipment sensitive to power surges. This type of generator provides higher fuel efficiency and lower operational noise ratings in a lighter model than home and work generators produced by Honda.

    EU3000i Handi Specifications
    • The Honda EU3000i Handi is a 3,000-watt inverter generator that features wheels, folding handle and a recessed convenience light. The engine is a Honda GX160, which features a 163-cc displacement. The AC output is 120 volts, with an average rating of 2,600 watts and a maximum production of 3,000 watts. There are three receptacles to include a 20A, 125-volt duplex and a 30A, 125-volt locking plug. The DC output is 12 volts and 100 watts. The EU3000i can hold 1.56 gallons of unleaded fuel, which will provide consumers with 3.6 hours of run time at 25 percent load for 7.7 hours.

    Is it possible to lower the output voltage? My unit is running closer to 127vac?


    Hi,
    The voltage runs that high when there is no load so that as you load it the voltage will not dip too low...usually the higher voltage will give less trouble then low voltage will.. you also will use less amps. to run anything at a higher voltage... this places less stress on the generator...

    I would not mess with it...when it is fully loaded you will be down under 120v

    We have a Valsi 5500 watt generator that isn't putting enough voltage out to run everything in out small travel trailer. It runs the lights but doesnt push out enough voltage to carry the A/C, microwave,...


    How long have you had this generator?
    Has the generator worked on all of these loads before?
    Model 5500 is a 5500 Watt generator which could easily be 5500 watts (Peak) and not continuous.

    Your AC is an inductive load.
    Your lights are resistive loads

    An inductive load can cause issues when starting due to an increased current demand at start up that some generators cringe under. Do the lights flicker or are they stable? I'd say your diodes on your stator are working if you have light stability but you haven't provided nearly enough information for a detailed solution.

    I'm sure you have enough voltage but you aren't getting enough current to run specific loads. How many watts is your AC? How many watts for your microwave? Both of these units demand a great deal of energy to run and when you place too much demand on your generator, it will choke it out and eventually, will cause damage to the generator. You may consider getting a beefier generator with a greater amount of wattage output.


    Seeing these specs online and noting what you are trying to run, you have an undersized generator and need to get one that can produce a greater amount of running wattage (as well as peak wattage).

    Just paid over 1,500 last year an has not rungood since. starts up real good, but once aair is turned on it stops running, or it might run one air at times. on my way back to michigan an not a happy...


    This generator is a 5KW model. This means it can supply up to 5000 watts of power, total. Not all devices list the watts they need to be provided - instead these devices list the power they need as volts and amps. This can make it hard to determine what the actual watt requirements are for the device.

    Overly simplified, watts is equal volts times amps (watts = volts x amps). A single 120 volt light bulb that uses .833 amps consumes 100 watts. If you checked a regular 100 watt light bulb with an ammeter, you'd find it does indeed draw .833 amps.

    Working the formula a different way, we can learn how many amps this 5000 watt generator can supply at 120 volts, too. If all the loads you need to connect to this generator are 120 volt types, that means the total amount of amps the generator can supply is 5000 watts / 120 volts = 41 amps purely resistive loads (like a toaster or light bulb) maximum under ideal conditions. There is never a time when ideal actually happens, and not all loads are purely resistive - many are inductive. Inductive loads are motors (like your A/C), fluorescent lamps, computer power supplies, etc. - so figure more like around 30 amps total instead.

    If you try to connect devices that require more than 30 - 35 amps, the generator will probably have problems trying to supply this load for any longer that a short length of time. Additionally, motors like those in A/C compressors draw significantly more power when first starting and can cause the problem you are describing. Try running the generator with loads other then the A/C to see how well it can supply the load(s). Or try running only 1 A/C unit and other non-A/C loads.

    What I'm trying to tell you is that you may need to do some active load management to be sure that you aren't trying to get more power out of the generator than it is capable of supplying. You may need additional generators or swap this one to a larger size to handle the load properly and safely.

    I hope this helps & good luck!

    What is the cprimary load on a 12volt to 240 volt 300watt inverter


    Ohm's law tells us that: volts = amps x resistance and watts =volts x amps. Watts (300) = volts (240) x Amps (?); or 300 / 240 = 1.25 Amps That means the inverter can supply up to 1.25 Amps to a 240 volt load.

    The primary is 12 volts, this is just 1/20th of the secondary 240 volt output. Since the best you can ever get is 100% efficiency -this means you'll need to supply 20 times the current. 1.25 Amps (at 240V) x 20 = 25 Amps (at 12V). As a check, from above Ohm's law that states Watts=Volts X Amps we get: 12VDC x 25Amps = 300Watts. Check!

    Some side notes. The Ohms law used above is for DC circuits and purely resistive loads on AC circuits. I do not know what your 1.25 A @ 240VAC load is - but I suspect it won't be purely resistive. Also, since we're working with an electronic inverter as opposed to a transformer and DC rectifier there are some things that push losses higher. You might need to provide a 30 Amp 12 VDC source voltage in order to provide the 1.25A @ 240VAC output. Lastly, I wouldn't not run the output at maximum for long periods of time - or at all. 1 Amp @ 240VAC would be much better.

    I hope this answered your question & good luck! Please rate my reply - thank you.

    Just up graded from a homelite 4400 to a craftsman 5600 generator 5600 does not have enough output as did the 4400 why


    Some manufacturers tend to fudge the numbers and throw around the 'peak' output power as continuous and it isn't. Peak (or surge) is the power a generator will handle as starting current (for example) for a motor and can be 120-140% of the actual continuous power.
    Check you owner's manual, find the detailed specs which will normally contain the maximum continuous current rating. If it is listed separately for 120 and 220 (240) volts look for separate current ratings for each output.
    By multiplying the current(s) times the output voltages you can find the total resistive output into a purely resistive load such as an electric heater.
    For example: 120VAC X 20 A=2400 watts. If other outputs are available such as 220VAC, multiply its current rating: 10A. or 2200 watts Adding those two results 2400 2200=4600 watts will give you the rated power of a unit.
    You can also recognize stupid power claims if the engine's horsepower is given. One (US) HP = ~746 watts. Since no generator is 100% efficient, its a fair rule of thumb to guesstimate the available electrical power at ~70% of the engine's rating (although, this is often also wildly optimistic). 10 HP X .7= ~746 X 7 or a bit over 5,000 watts.

    So, i think I've blown the fuse in my Marshall MG 100 HDFX head (I tried to run 2 speaker cables out of the head into a quad...stupid >.<). What type of fuse do these heads use? How can i access...


    The fuse is inside the unit so as to force you to open it and look for damage.

    The fuse is likely a 3 amp/250 volt type.

    Replace the fuse and then put a 100 Watt light bulb in series with the hot side of the power input. If the lamp stays lit with no load on the unit, then there is damage that requires repair before use. If you just replace the fuse repeatedly you may damage further components.

    In the future obey the minimum resistance load on your amps.
