I am new to RVing. I am trying to book a site that has 100amp hookup. I only have 30 amp RV. where do I get an adaptor for a 100 amp to 30 amps Adaptor. I found 50 to 30 but nothing for 100 amps.

From what I read those are usually 2x 50 amp connections. You should just need a common 50/30 adapter.
Call and verify. Good chance the camp store will have what you need.

I am thinking you make be confused on 50 amp hookup. 50 amp hookup actually gives you two hot legs of 50 amps each for a total of 100 useable amps. But since you have a 30 amp rig, you can actually get no more than 30 amps no matter what you hook to.

I think some high end sites for large motor homes do offer 100 amp, but as mentioned, I think that is 2 50's. Call and make sure.

I'd give the park a call to be sure but betcha they mean a 50-amp hookup. I believe that a 50-amp hookup actually delivers 2-legs of 120VAC/50-amps. either way your 30-amp rig will draw no more than about 80% of 30-amps.

It can't possibly be 100 amps if it's a CG/RV park. Code requires either a 30 amp at 120 volts or 50 amps at 120/240 volts (like in a house), or both on a site. Maybe they are incorrectly referring to a standard 50 amp site as 100 amps because a 50 amp pedestal/site has two hot legs that give you the same amount of power as 100 amps at 120 volts.

If you have a 30 amp RV, a standard RV 30 to 50 amp adapter is a good thing to have regardless. The receptacles in 30 amp pedestals can sometimes be in poor condition and you may need to plug into the 50 amps in a pedestal or move to another site with 50 amps.

Up until 2017, the code (NEC) only required a CG to have 20% of sites to be 50 amps (and only 5% in older CGs) and getting 50 amps can be difficult sometimes, if not impossible and 30 amps is usually what's mostly available.

What the park is referring to is a 50 amp site. To plug your 30 amp rig into 50 amp service you want a 50 amp Male > 30 amp Female Dogbone.

Not plugging at all works too! Don't become a slave to hookups.

Forget you ever heard of 100 amps available. I'm just gonna leave that there. You should also. Your choices are 50 amps 4 wire 120/240 volts and 30 amps 3 wire 120 volts. If you rig has a 50 amp service then you have 240 volts delivered to you circuit breaker box. That is where it stops. You cannot access 240 volts there. 120 volts 50 amps to the left of the main and 120 volts 50 amps to the right of the main. You have two 50 amp 120 volt legs to use. BUT if you exceed more the 50 amps on one leg the 50 amp main will trip. There are dog bone adapters available but you will only get 120 volts out of them. 50/30 and 30/50. Also 30/20. If you plug your 50 RV into a 30 amp outlet using a dog bone you will only get 30 amps.

Most park boxes that have 50 amp also have a 30 amp and a 20 amp receptacle in them. Not 100% but most. As long it isn't 50 amp only you don't need any adapter.
