Thor 24.1 amp usage ?

Is there a list out there that shows how many amps the stuff in the RV uses ? How much does the fridge pull ? The water heater ? The TV sets ? Coffee pot ? Hair dryer ? Microwave ? Etc ... thanks, I realize that Itís best to know what uses what ... thank you !

There is such a list that I found taped to the inside of a kitchen cabinet door in our unit; which I presume the previous owner found somewhere. I'll see if I can get a picture of it later this afternoon. I do not vouch for it's accuracy - it's probably a generic average for various appliances. Your mileage may vary.

Here ya go! Again, these are averages, older models probably - but will at least give you a ball park estimate.

After I installed my volt/ammeter I measured all the "high current" stuff and it all drew 12 amps! LOL (A/C steady state, hair dryer, microwave, water heater on 120V, induction stove, etc.).

Realize that DC amps are 10 times the AC amps.

So if your furnace is pulling 10 DC amps that would equate to only 1 AC amp out of your 30 AC amps available.

I learned a lot from this last power outage. Great people on this forum and great people available at Disney Fort Wilderness. Free counseling on sight so mistakes aren’t made again. Just FYI.. taking off the surge protector is never a good idea. Secondly, hooking your 50 to 30 amp should only be used in an emergency and if that happens know what your using or you can burn your 30 amp wire. Your surge protector doesn’t protect you for that. I am much smarter today than I was yesterday. Thanks for many experienced peoples responses and the journeyman at Disney Fort Wildnerness.

No Sue, you still don't have it. If you have 50 amp cord and plug into a 30 amp outlet, using a dog bone, that means you are protected by the 30 amp shore power breaker. A 50 amp RV does not have a 30 amp wire to burn up.! People plug 50 into 30 all the time with no issues using a dog bone adapter. 50 amp cord has #6 wire good for 50 amps.

Many people plug their 30 amp RV's into 50 amp services DELIBERATELY because the 30 amp outlets are very much used and worn out and provide for a LOOSE connection.

If a person has a 30 amp service in the RV, they can plug into a 50 amp outlet, using a dog bone, with no problems because the would be protected by the 30 amp main breaker in the RV. You can not pull more than 30 amps. 30 amp cord has #10 wire good for 30 amps.

LOTS of people go thru their camping lifetime NEVER having used a surge protector.

Yes many people do - and the risk is minimal... But a problem between the pedestal breaker and the RV breaker could subject the main cord and transfer switch to a 50A load before tripping.
Anything downstream of the RV 30A breaker is protected against any draw over 30A.


Much higher risk that something loosens and causes heat without tripping a breaker - that can happen whether plugged in to 30A or 50A service.

True - and feel free of course - its a personal choice.
I use whole house surge suppression device in sticks and bricks home - and in RV... and both have saved me based on damage neighbors saw...
I watched/heard my whole house surge suppressor give its life to a power surge coming out of a blackout... I replaced a surge suppressor; neighbors replaced electronics and appliances...
I've had at least two issues I know of where I believe the surge suppressor in my RV saved me... Once again neighbors had damage from a surge event and I was fine... And another case where the surge guard cut off my power for low voltage, and we found a bad breaker in campgrounds main distribution panel.
Make your choice based on what you are comfortable with.

Remember in a perfect world with no efficiency loss in the converter divide the 12DC amps by 10 to get equivalent draw on the AC side. IE with a 12 amp DC load it would draw 1.2 amps on the 120Volt AC side
