ok so I have seen on here that 30 amps is 30 amps and 50 amps is actually 100 because it is a 2 pole breaker ... is this true or false and I want to ask also if the 20 amp plug at the pole is gfci then can you run a heater on it?

Yes.. with 30 amp service you have one 120 volt 30 amp line. With a 50 amp service you have two 120 volt 50 amp lines. For the record nothing in your rig runs on 220 volts. On a 50 amp service, half your rig will run on one 120 volt 50 amp line, and the other half will run on the other 120 volt 50 amp line. Typically your A/C's are each placed on a different line, along with a balance of the rest of your appliances/outlets. This is why when a rig needs 50 amps and a guest will say I have an adapter I can use 30 I try to explain to them that a 50 amp service supplies 3 and 1/3 times the power of a 30 amp service and half your rig will not operate on 120 volts. '
Depending on the size of the heater, yes you can run that on a 20 amp outlet. 20 amp is typically the highest rating on an outlet in a brick and mortar home. 20 amps X 120 volts means a heater of up to 2400 watts can be run on a 20 amp outlet. Know that many campgrounds will have more than one sight on the same line coming from the main campground panel. That 30 amp line at your sight may be on a combined 50 amp breaker, meaning, if you and your neighbor both run the max, the main breaker will blow, not at your campsight. Have I totally confused everyone ?

I should add, all of the above goes into figuring site sizes and what type of unit will fit on what site. It's not just the physical size of the unit, but also the utility requirement of that rig. On average a rig under 34' is assumed to need 30 amp service and over that 50 amp service. We try to ask a guest when making a reservation what they need so we can place them in the correct size sight. So when you lie and say you have a smaller unit than what you really have ( especially when reserving online) you really could be setting yourself up for problems once you arrive at your site.

A ground fault circuit interrupter (GFI) just detects a small voltage "leak" and shuts the line down before anyone can get a shock. It makes no difference as to what is plugged into it.

This is a typical 30AMP Wiring configuration showing what runs on 120VAC and 12VDC.

Note the trailer battery and the 120VAC controller 12VDC OUTPUT are both connected to the same point on the 12VDC Fuse Panel. This allows both the Battery or the Controller to provide 12VDC going to the 12VDC fuse panel. If the controller is not powered by 120VAC then the battery carries the 12VDC load.

With the battery connected then the converter will keep the battery charged when the converter is connected to 120VAC shore power.

The electric is confusing for everyone.. 30 amp and 50 amp really confused people. Many older campgrounds have limited 50 amp sites, and when they use an adapter to plug into a 30 amp receptacle and they have problems they are surprised.... and of course it's all the campgrounds fault.

Roy Ken,

I think I found a mistake on the diagram. At the bottom it says, "Power Inverter (from 110V to 12V) is custom install". Inverters convert 12v to 110v, correct?

It appears in this case, since your inverting power from the 12v battery to 120 volts for use to power TV and outlets your correct. On a side note, this would kill the battery quickly depending on what your plugging into the 120v outlet.
