I am new to this forum (thanks bbb) and have a problem with my lights... I have 6 500 watt halogen lights and just bought a 3500 watt powertrain generator and it will only run 4 of the 6 lights. I thought the cord was the problem so I split it up the light on 2 separate plugs and it still only runs 4.  I do not know enough about this topic to fix my problem obviously so maybe one of yall can help me.
Thanks in advance for any help.
Ben

| Your generator is 3500 starting watts but how many running watts? Your lights need 3000 watts to run but probably more to start up. Also sometimes you need to look at amps and see how many amps your pulling and how many amps your generator puts out. Sounds like you're just overloading the generator.

Also sometimes you need to look at amps and see how many amps your pulling and how many amps your generator puts out. Sounds like you're just overloading the generator. If he has a powertrain 3500, it is rated for 3500 continuous with 4450 starting. Now most likely you are over burdening the outlet output rating of 20 amps. Most small generators will not give you more than 20 amps out of a normal 3 prong 120V outlet. I see that your generator has 1 120 volt twist lock plug that is 30 amps. You might need to create a juntion box with normal 3 prong outlets to plug your lights into from this 30 amp outlet. But at 500 watts and 110-120 volts each light is drawing about 4.5 amps for a total parallel draw of 27 amps for all 6 lights. Which exceeds the 20 amp rating for the 2 120 volt plug ins on your generator.

Ben Your generator is most likely only designed to only put out between 2800-3000 watts continuously and 3500 in a surge as when you are starting up something that has a heavy draw to start with and then evens out. My Honda 2000 is only rated to continuously put out 1600 watts. If this isn't the case your probably still gonna be having problems with to much amp draw. Is the circuit breaker tripping? I need a little more info to properly address the question.

What size wire do you have going to the lights? Is is a standard 14 or 16 gauge extension cord? Your best option would be to buy 300 watt bulbs and change them out. Not much difference in light output and would cut your amps down to around 15 amps, which your generator will handle. Also, measure the voltage on one of the plugs with the lights on and see if the generator is putting out 120 volts with that kind of load on it. If the voltage drops, the amps go up.
