    I am going to get a rack or something put on my trailer tongue to hold my generator. I have no idea what I need, other than the genny needs to go there and I'd like it to be lockable to prevent theft. A padlock and chain are ok as the theft concern is only a temporary thing, usually I don't worry about it.

    Is it possible to have a solid box to cut noise? Just open on the muffler side? Is it possible to have a "roof" to shed rain and let me use it in the rain without being a total electicution risk?

    I'm sure the welder has done this before, but I'd like to have an idea of what I'm wanting before I go in there, but I don't know what's possible.

    Also, can this rack contain a ground of some sort so that I can't accidently energize my trailer? Is that necessary and how would I do that (I see a wire going to the jack???).

    Thanks
    Jena

    What type of trailer are you going to mount the generator on?
    What are the dimensions and weight of the generator?

    Yes, it is possible to mount it in an enclosed box. However, you will have to design it for accessibility, heat build-up and sound proofing.

    I'm sure the welder has done this before, but I'd like to have an idea of what I'm wanting before I go in there, but I don't know what's possible.

    For a good metal fabricator just about anything is possible if you are willing to pay the price.

    I will let someone who is more electrically knowledgeable address this last question.

    This will be on your rather large meat locker trailer, running the refrigerators right?

    Roof is good, totally enclosed would be a problem I'd think - the engine needs to get rid of heat, get rid of exhaust, and intake clean air, you would need it screened at the most....

    Grounding a portable generator. Hum. I'll sit & watch for intelligent replies on that, my thoughts would just be guesses. Good question.

    Since welding gensets are enclosed it must be possible. I know my butchers genset is not and I don't think I ever saw a ground which is an excellent point! By his own admision he made a few errors building the thing. Don't forget vibration, it will need to sit on rubber mounts or it with put an uncomfortable shake through the whole trialer. Noise was a big concern too, look at extra mufflers or an extension to get the exhaust up Pretty sure Honda makes what you'd need for their stuff anyhow. Grounding should use a proper sunk intot he ground earth, maybe you can install a perminant one near to where you are and run a cable, otherwise mabe a spike on a seperate jack that will drive into the ground as much as you can? Ask an electrician!

    Perhaps we are talking in relative terms, but i've never seen one 'enclosed' - I've seen them with some nice lovured, vented side panels that would shed rain but let lots of air-flow. Or side panels that have to flip open for use.

    On the grounding, my guess it that it's important for electricity to be grounded from source to use - the gen set to the trailer frame to the refrigirators (or whatever) but in this case, to actual earth would not really be extra important. But that is just _wild_ speculation on my part, I don't really know.

    The only time grounding would be an issue is if the trailer was either connected to a grounded source (such as the electric utility or off-trailer generator), or if the on-trailer generator were used to power off-trailer loads.

    As Paul stated, if the on-trailer generator is supplying on-trailer loads only, then the only grounding requirement would be a common (the generator and the loads) ground to the trailer frame.
