No Iím sorry, I meant I have a whole different inlet. I purchased a 15amp inlet originally then purchased the 20amp one when I decided on running an electric water heater and I still intended to install the 15amp just to have if we ever need it.

Running THREE cords to a pedestal is likely to annoy the park owner, who has an interest in not having his electrical system overloaded or damaged. Or having you use more power than you're paying for in the daily rate - many parks in areas with high electricity rates charge more for 50 amp RVs than they do for 30 amp rigs based on the higher expected power usage.  Running two cords to the pedestal to get extra power is bad enough, three is definitely pushing it.

The RV will be plugged into the 30 amp pedestal outlet, the water heater will be plugged into the duplex 20 amp (or 15 amp) GFCI outlet in the pedestal and you'll plug in the 15 amp cord where?  Not into the second outlet in the GFCI, you'll still only be able to draw 20 amps out of it.

If you want a dedicated outlet, I'd just put the second breaker in your box (you have room for it) and just use either the hair dryer OR the water heater.  Turn on one, turn off the other.

Or plug in the room heater or hairdryer elsewhere in the trailer. which come off of the 30 amp plug.

You could set it up for an additional 15 amp service but you would not find an additional source to power it at camping facilities. Typically all you will have available is 50, 30 and 20 amp options. Some may not have all those options.

That will work fine, and can be run through the same box - separate breakers.  Note, however, if you plug both cords into the same receptacle, the receptacle will limit you to 20A total on the two cords.  To get full benefit, the two cords must be plugged into separate circuits.

It's not a dumb question if you do not know the answer.

Typically, service cord (S/SJ/SJOOW, etc.) is not listed for permanent install, hence why itís called cord and not wire. Itís technically not supposed to be hard-wired into a panel, except in cases like concerts, festivals, or conventions where itís tied into a disconnect on a temporary basis. Otherwise itís supposed to have a plug and be able to disconnect. Using it in a permanent fashion isnít really unsafe in your case where Iím assuming itíll be protected inside a cupboard or storage bay, but it just depends on how tight you want to stick with NEC rules.

I'd use the UF rated romex.  That's the one that's rated to be buried without conduit or for use in wet areas.  Maybe overkill, but then again, maybe not.

If any of the wire will be running on the undercarriage of the camper youíll definitely want to use UF.

None of it will be. Iíll be running about 4ft total and it will all be within a cabinet. I just have to figure out where Iím mounting my breaker box and go from there

Looks good to me.

My only observation would be to leave the wires inside the box a little longer. So in the future if you need to move something around you have the wire to do it.

Thank you!

Was having quite a time bending the wires around in the small breaker box



Does anyone know if I should be ground this breaker box to the trailer frame? Someone told me I need to
