3 position Transfer Switch
I have an older class A RV, I was thinking about installing an inverter but wasn't exactly sure on the wiring. To me the easiest way if it's even available would be to have a 3 position transfer s...

They do make 3 position Transfewr switches. I've seen one mess up and burn out the inverter.
Inverters come in two x two types and many sizes.
First types: In line, stand alone
In-line are typically inverter/charegers.. They have 120vac inm, and out. And a built in transfer switch for the loads they powewr
Stand alone: These just turn 12 volt into 120 volt ac Period
MSW/ TSW (or PSW).. True/Pure sine wave is best, i'm going to end that here for bandwidth issues.
Size:
500 watts or less: often factory installed,m Just enough for the main Entertainment center.
1000 2000 watts.. This adds some additional stuff, possibly the GFCI chain or the bedroom. or a Residential Fridge..
2000-3000 watts: add the Microwave,
3000 and UP this is enough to run a single A/C. This type may be used with a "Whole House" 3-way transfer (And in fact is the one I saw "Smoked".)
I do not recommend this because A/C's at 13.5 amps (Mine) that's 135 amps at 12 volt. plus overhead and inverter loss, Will run my batteries down in almost no time flat. And that is far too much load for the Alternator.
How to wire an inverter so it does NOT power Water heater, Roof top A/Cs and the like.
Main panew--branch--Invwerter--_Sub panel--Inverter loads (TV GFCI Microwave)
The main (Generator/shore) transfer is before the main panel.
The size of the branch breaker (mine is 30 amp) depends on the inverter.
The "Sub Panel" may be part of the inverter,, or not.
True story:
Camper complained "half my outlets are not workign including the microwave"
I ask if he had an inverter as we walked to his rig.
First door he opened was batteries
Second was invewrter
One breaker was clearly off (Bad design, the breakers are supposed to be around back where you have to feel for 'em but these were right there ewere you coudl see 'em clearly)
Turned it back on and ask him to go in and check.
Wife asks him (As he enteres) "Does he think he can help??"
Husband, noting light on Microwave clock "He's already fixed it".
I love it when the job makes me look like a rock star :)
