Generator question!!

I recently bought a boat set up with 3 400w HPS lights, 24v trolling motor, and 2 power converters to charge trolling motor batteries. I chose to not buy the 3500w Honda genny and get my own, so I bought a 3500w champion I hear so many good things about. I had to buy a new 4 prong plug (l14-30p). The wires running everything has a hot, neutral, and a ground. Got it all running in the 240v side of the genny but after about 5 min it overloads and shuts the lights off... I was wondering why the overload since the guy I bought it from used a 3500 w generator? I am thinking maybe I could use another hot wire to attach? Any help would be appreciated! I am guessing my total watts to be 1,200 for the 3 lights and 1,000 for the trolling motor? I am electrically retarded so if anything I said didn't sound right... : )

i have 2 powermax converters to run the 24v trolling motor. there are 6 110 plugs (or) 3 boxes that look like house plugins, 3 separate 110 plugs-ins for the lights and 2 for the converter. all wires run from 110 boxes to a central location where they turn into the chord that has a ground, a neutral, and a hot wire that runs to the l14-30p plug that goes to the genny. the trolling motor may be more than 1000 watts but i think i did the ampsXvolts=watts right. that adds up to 2,200 watts going in a 3,500 watt genny.

Ok! So it's 1000 per side and obviously takes more juice running trolling motor wide open? Would it make it better if it was wired with 2 hots, a neutral, and a ground or is 1 hot enough?

OBG be on here before two long he will have all your answers.

I do know that 3-400w hps pull more than 1200w

Ok just thinking out loud someone correct me if im wrong. If your lights on 240v pull 1.9a which is 228w each thats 684 total on lights, an converters pullin 2k. Thats 2684w. Your genny is a 3500 thats prolly peak which would make it a 3000 running watt genny. You can only go 80% of that capacity which is 2400w. That puts you 284w over...i think

That's what i thought. That's where my logic stops and then it starts back with getting speaker wire, running it to all the hot sides of the 110's and then taking it to the #4 post on the plug... : ) aluminum won't burn in an electrical fire will it?? Lol

I ran all that and those two 150hps that are on the back off that eb3500 honda. I had it all wired, the converters and 400hps wired into one 20amp plug and then the two back lights were just on the regular plug in. Worked fine ran the troller maxed and never had a problem. I know that doesn't fix the problem but that is how I had it hooked up.

i personally would because you only have one hot to deal with and ive heard a lot of people saying the 120v power is more constant than the 240v. if you go 240 then run half your stuff on one hot and the other half on the other hot. dont use speaker wire. i used a 10gauge outdoor extension cord wire.

yes, by using it you get max wattage on one hot wire instead of two, but if you already have the 220 and dont wont to spend the extra cash on a 120 rv plug just run a second hot wire having half your stuff on one and the other half to the other. if i was doing it i would just do the rv plug for the simplicity of it. if you have two of the regular 120 outlets you could also run half your stuff on each of the two outlets. hope this helps.
