We always kept the TT in storage but now keep it in our side yard. We use the 30a to15a dogbone but we will be having the proper receptacle put in place so we don’t have to bother with extension cords and adapters anymore. We currently have a 30a TT but will be upgrading to a larger one when the kids are out of daycare, but that’s still like 4 years away. Our electrician is a camper so I’m confident in his work but I don’t want to bother him until we are ready for the work. Let’s say we wanted to have a 30a and a 50a receptacle installed. We would use the 30 now and the 50 when we finally upgrade down the road. Would we need a dedicated 50a line AND a dedicated 30a line run to their respective receptacles by the camper? Or would we only need one dedicated 50a line and then they’d splice the line behind the receptacles to feed the 50a and the 30a receptacles? We wouldn’t be using the 50a and the 30a at the same time. We do have a 50a to 30a dogbone just in case the 30a receptacle at the campground is down.

All you need is the 50A line and the 50A and 30A receptacles can be run off that. I am not up on the code for that but it may require you to change the receptacles and breakers when you change to a 50A RV.

An RV electrical panel like this is best way to go. Wire from your main electrical panel with wire correctly sized for the distance. Number 6 would handle the load.

Wire and install a 50 amp. Use a 50 to 30 dog bone.

TT 50A is a 240V/50A 4 wire circuit with two 120V/50A legs, two hot, one neutral one ground.

30A is a 30A/120V 3 wire one hot, one neutral, one ground.

If you plan to eventually go 50A, have the system wired to support both. A 50A/240V 4 wire from the main breaker box feeding the "trailer box".

Just make sure the don't wire the 30A as a 240V circuit!!!

Very few errors with a NEMA 14-50. The errors happen with the NEMA TT-30.

When I was running the outlet for Dads 30 Amp trailer, I buried wire needed to carry 50 Amp. On the post I wired 30 Amp outlet for camper, and on same leg, 20 Amp breaker, feeding duplex outlet. When changed to 50 Amp, just had to change plug, and breakers.

The breakers in that panel look to be Canadian, not US type.

This ^^^^^^ was the route that I took, even though I have never owned a 50 amp RV. If I ever upgrade to a 50 amp RV, I have the power for it. I used 6 gauge wire (with 10 g for the ground), but I only had a 30 foot run, one way, for a total of 60 feet of wire.

CHINT breakers are made in China and used pretty much worldwide, including in the US.
