food truck/ trailer

OK so my electricity was done a month ago the light fixtures were installed. i connected the generator. The light turned on they were bright then seconds later they started to smoke and fire and they burned. Why would do they do that? I checked the outlets i have 5 outlets and Two outside. 3 were hot/ neu. Reverse on my circuit tester would that have caused my lights to burn out?

What generator are you using & what regulates the voltage & amperage?

If you want any help you are going to have to give us ALL the details. Start by completing your profile so we know where you are located.

Explain in detail what you have for this food truck/trailer. Explain in detail the wiring you did or had done. Is there any battery-operated lighting or equipment in this truck/trailer? What kind of generator was installed and what is the voltage of this generator?

Pictures of the entire set up may be helpful. For this I recommend taking a couple of dozen pictures of anything and everything electrical, both close ups and from a distance so we can see how the entire thing is set up. Remove any covers over circuit breaker or fuse panels and get good clear, in focus and well-lit pictures. Fuzzy dark pictures are of no use.

Pictures will help but we need to know about what wiring was done on the trailer. If your tester was showing that some of the outlets had reversed hot and neutrals that could indicate that the wiring was not done properly/professionally and sorta makes me suspect all of the wiring. Not that switching hot and neutral would or could cause the wiring to catch fire but if that simple mistake was made you've gotta wonder what else might have been done wrong.

It will also depend on the type of light fixtures you are using (we need that info too) If they were low voltage, and connected to 120 volts, that will kill them quite quickly.

This is the box I have with 4 (20 amp) breakers, the lights turns out they were meant for garage if that makes any diffrence low amp 120v. I only have the cuircuit box to distribute the power the generator is 5500 generator i believe. I took 30 pictures total but having problem to figure how to post them. The electric outlet I opened it up and it looks like its connected on the right a white cable on the top screw on the left thre are three screws from top to bottom 2nd screw has the black wire the third one has what i think ground wire screwed on.

I see a dead short in this picture. Or a sure looks like black and white are on the same screw. If they are on the same screw wiring was done by an idiot and should probably be redone from scratch.

Pictures of the breaker panel with the dead front on don't help us. Remove the cover so we can see the wiring.

What is the voltage output of the generator, 120 or 240 or 120/240?

Clarification: I'm seeing black and white on the same screw but the image is too blurry to be sure.

From where I sit it looks like the black and white wires are reversed. This will cause a dead short between the black (hot) wire and non-insulated ground wire through plug.

Agree with Ray 2047.

Actually that wouldn't cause a short. I'm seeing black and white on the same screw but the image is too blurry to be sure.

The white is looped but it's still on the brass screw. The black goes to the other side. It's hard to see.

OK I think its 120/240 that is what it says on the generator front cover where it has the connections. That's electrical tape around it but when i connected the generator i tested and connected a lamp and fan to every outlet for about some minutes they get power and work but i still want to fix the problem I'll takes picture of the outlet

I don't think so, Ray. I agree the picture is too blurry to be absolutely certain but I think Rooster is correct that the white and black are simply reversed. One thing that did jump out at me is how shallow the steel boxes are. I think it is highly likely that when the receptacle is pushed back into the box the bare equipment ground lead is touching the miswired black lead.

Thing is, if the "electrician" made these simple errors what else did he get wrong?

Yes that's what I been calling him since yesterday among other colorful names lol but when you mean redo it from scratch does that mean to put in new wire from the electrical box to the outlet?

Take a look at your outlets. When facing the outlet like you're plugging something in the black/hot goes on the right. The same side as the shorter of the two slots in the outlet. The white goes on the side of the outlet with the longer slot.

Is the part of your food trailer where the outlets are located required to be capable of wash down?

Based on others comments I will retract my statement of both wires on the same screw.

Since there is no up or down on receptacles likewise there is no left or right. Using terms of left and right also is dependent upon which side you are facing so left/right and up/down are meaningless.

What you DO need to know is that the white wire ALWAYS goes on the white-colored (silver-colored) screw and the other color, most often black but could be any color other than white, grey or green, goes on the brass-colored screw. Even if you are color blind you should be able to recognize the difference between a lighter colored screw and a darker colored screw. White to light black to dark.
