Surge protector

If you are talking about a "portable" Surge Protector unit that push together type connectors, then yes. They don't need to be inside a box. If outside in the rain, I wrap a plastic bag around my connections - then wrap duct tape around the plastic bag outer wrapping. Probably isn't needed but IMO, all electrical connections should be kept dry.

Actually inside a "box" of some sort is the best protection for any electrical connectors and certainly wrapping those connections in plastic is the worst thing you can do as that will only trap moisture which over time will condensate into water inside that wrapping, just where you don't want it. 25 years in mobile remote television production and we always enclosed any connections that might be exposed to rain in plastic videotape boxes that we'd then suspend off the ground. Cables entered and exited these boxes via a notches which also allowed air to easily vent in/out and keep the connections totally dry.

To the OP ...

These portable surge protectors are designed to work outdoors but if you're so concerned about it just locate it at the trailer, tuck it under a slide or under the body of the trailer, and run an extension out to the power post. Another solution - install your portable unit inside the trailer, just as you would a hard wire model and just as I did with a TRC unit I used to own.
