Ex 5000 sx generator, no power

I have a 4500W honda generator. The engine runs fine. The generator produces 120V. power, but not 240 V. power. It is an older unit (1990's). Receptacles are located in the end of the generator. There is a reset button for the 120V, but not for the 240V receptacles. I can't find an exact serial number on the generator. The motor is a GX 270, VW12.

Hello dear, would you consider buying a new generator? Generator Diesel Generator Cummins Generator Volvo Generator Perkins...
If you can start your generator normally, you can analyze the reasons through the following article:

SOURCE: generator plugs doesn't match cord

Hey steve. do you really need 240 volts for 120 v. circuits. the reason you have to have an adaptor plug is because on your 220 volt plug in , 2 of tthose prongs are hot and 1 is ground. for safety you need to get a plug adapter ( a regular 120 volt plug end ) run a ground from adapter to ground on 220 adapter. same with nuetral. you also need to ground your generator. there is usaully a ground lug on the bottom of the gen. Another way. if you dont really need 220 v. is to use both 120v. recepticals on gen. Run 2 chords to tranf. switch. and hard wire it in to switch. another way i did mine . when i lost power in this hurricane. i ran two # 10 chords from my 2 120v. recept on my gen to my breaker panel. when you do this you have to pull the service meter, if you dont when power comes back on it would backfeed through your gen.then i turn all my 220v. breakers i was able to run lights ,ciling fans, freezer, ice box,washing machine and gas dryer , tv's computors etc. . but to do this, you probably need someone that knows what they are doin.

SOURCE: Operation of a Devilbiss GT5000 generator

not to familiar with the generators however , I do know that the old style receptacle for 240 volts was three prong. Then OSHA got a hold of it and added a second ground to make it 4 prong, Thats why some houses use a 3 prong dryer cord and some use a 4 prong. hope this helps. and if it has 2 240v outputs BONUS they dont make em like they used to.

SOURCE: 5500 generator stopped producing eletric after

First check with the dealer and see if it is still under warranty. If it is not, make sure nothing is blocking the air flow around where the control modules are located. This could cause the voltage regulator and other electronic parts to overheat. Next check the brushes and make sure they are free of any dust or build up preventing them from making contact.

If everything is OK the next thing I would do is change the voltage regulator.

Husky 5000 watt generator quit producing power.

You could have a bad circuit breaker button. Replace that and see what happens.

My robin subaru r1100 can I run it at 240 as it has a UK plug on it I tried to run a kettle but it started to cut out thanks

You need to determine output frequency. Is your engine running at 3000 rpm (50 Hz)? At 50 Hz this generator only produces 700 VA (850 VA max).

I just look at my coffee pot here and it requires 1000 VA (watts) of power. If is more power requirement than this generator could produce even if it was operating in 120v mode at 60 hz.

5000 watt inverter schematics circuit

If you have (90) 50w lamps = 4500 watts total. Assuming a 120/240 panel, if you put 1/2 on one "side" of the panel and the other 1/2 on the other "side" of the panel, that would be 2250 watts on each half. The generator should be rated *at least* 125% of the load; 4500w x 1.25 = 5625W. Using a 4500W generator on this load will cause it to overheat and shorten its life as it is running at 100% of capacity all the time..

One half of the panel is 120V to neutral, and the other is 120V to neutral - or 240V between both circuit breaker terminals. Ohms law for DC circuits and purely resistive AC circuits says Volts x Amps = Watts; or Watts / Volts = Amps. So, 2250W / 120V = 18.75A on each pole of a 2 pole circuit breaker that feeds the sub panel. A #12 copper wire is rated for 20 amps; but as per National Electrical Code - must be de-rated to 80% of rating which means it is good up to 16 amps maximum. A #10 copper wire is rated for 30 amps, but it too must be derated to 80%, making it good for 24 amps maximum. So, if you are going to feed a sub panel supplying (90) 50watt lamps, you will need to run a #10/3 copper cable from a two pole 30 amp circuit breaker at the generator to a 120/240 volt "main lug only" sub panel rated for at least 30 amps.

Divide your load evenly across the sub panel - (4) 15 amps circuits via (2) two pole 15 amp circuit breakers on each "side" of the panel if you run (2) 14/3 cables out to the lights - or (4) single pole 15 amp circuit breakers if you run (4) 14/2 cables out to the lights. No circuit breaker terminal should have more than 23 lamps that means you have (2) w/ 22 lamps and (2) with 23 lamps. The circuit w/ 23 lamps will draw 23 lamps x 50w = 1150W. 1150W / 120V = 9.6A. The 22 lamp load will be 22 x 50w = 1100W. 110W / 120V = 9.2A. Which is well within the 12A maximum allowed (after derating as required by code) by a #14 copper wire rated for 15A.

Good luck!

Want to add 240volt outlet to generator

You CANNOT do this, USA 240V is derived from a poly phase scenario, IE 120V line to neautral and 240V line to line, UK 240V is derived from 1 line to neutral it will not work unless you power a transformer

We are getting 155v on the 120 v receptacles

it may be running far to fast, just slow it down a little
how did you get this reading,,,on load or off load???
if off load hook up a light bulb and take another reading,,if its pulled the volts back down thats fine,,,if not plug in to the geny some thing thats close to its full load,,,"not more than this" now take the reading,,,
if still high lower the reves till its just 120v on full load
mind you,,,5000watts? thats a big un!!!!

No power output from my generac 5000 power plus.

sounds like you need to "flash the field". This means you've lost you excitation voltage for the generator to produce electricity. In most cases you need to get a 9volt battery and connect it to 2 & 6 inside the generator. They are Blue & Red wires, but they are not the only blue & red ones there. The generator should be running and the battery should only be connected for about 5 seconds. This is very dangerous because of all the high voltage and democrats.
