Converting to 50 amp

It's not all that's cracked up to be. As one poster had said "converting to 50 A is more involved". Some RVs that come with generator has an interlock relay that isolate the generator from shore power every time the rv is plugged in to the pedestal. More like a transfer switch on a solar powered system. When you convert to 50A you will have two separate 120v source using both legs and common neutral of the 240 source. The interlock relay that comes on a 30A panel needs 120v. Since you will be using both 240v hot legs- you can't use this hi voltage to energize the relay coil because it's only rated 120v. There is of course a workaround if you know what you're doing--thus going back to " more involved". It's not just yanking your 30A panel and throwing in a 50A and hope that everything will be a piece of cake. It would be a remiss to assume that anyone who can replace a wall switch is capable of this undertaking.
Do yourself a favor and consult a certified electrician, it may save you from any catastrophe. If you are hell bent on diy (to prove your manhood lol) go for it. Just don't tell anyone you read this. Good luck.
