We are new.... ( obviously). We want to begin to learn about our new to us 86 GV3300... we have checked our home breakers and see that we have 15, 20 and 30 amp service on some outlets throughout the house and garage. If we took out 50 amp cord and stepped it down with adaptors to a 30 amp grounded house outlet.. what could we run as shore power to give us lighting, electrical outlets for small tools, we nee to mount a flat screen TV after hours ( after our work day) and want to park in our home driveway and hook up to something... we know we won't be able to run our AC but all ok in the evening in Boulder Co..
30 amp would let you run all you have mentioned even a microwave.
Make real sure how that 30 amp outlet is wired. A 220 volt drier outlet will fry many components in your rig.
BE CAREFUL ^.^d
I WIIL BET THAT 30A IN YOUR HOUSE IS 22OV !
The outlet needs to be 30 amp/120 VAC= ONE hot, one neutral and one ground. Period.
Heed the warnings lest you liberate the smoke...
Understood. I will check our breaker box labels and switches.... might be just 20 amp for household use. We understand the issues with the DRYER plugs.... not the same.... so.. i can step down from the 50amp RV cable with adaptors all the way to the 120 V 20 amp and use for powering up some things in our driveway..... is the house battery ( salesman's switch ON or OFF... inverter ? Or automatic once all plugged in. ?
As long as no one gets the wrong idea: we're in a 30 amp park that will change voltage in the aft. with high usage. We can only use one AC, nothing else, during that time. That's where a EMS is a must!

Be nice if you had a set of electrical schematics for your coach - makes it a lot easier to understand how stuff is connected.
NORMALLY, when you plug your coach into shore power (regardless of what kind of adapter is used), the shore power goes to a ATS (automatic transfer switch). The ATS also has a input from the generator. If the generator is not running, then the ATS passes power on to the main breaker panel. From there it is distributed to the different circuits in the coach. So if you are just plugged into a common household 20 amp socket, you will have the 20 amps available to all the 110V outlets in the coach. You can't put any more load on those circuits than you would be able to in your house. 20 amps is 20 amps.
The salesman switch doesn't have anything to do with the 110V power circuits in the coach. It is normally used to turn off some (but not all) of the 12V circuits in the coach.
Yes, you can use a 15/20 male to 30 amp female adapter AND a 30 male to 50 female adapter and plug right in-- as long as you do not exceed the total amp draw of the 15/20. And if other things in the house on the same circuit, the total counts.
I will BET he has a 12v converter mounted upside down in the plumbing bay on the pilot side near the rear wheel. If the battery's are down this will take a lot of juice... can turn it off by the bed circuit panel..
And it hurts the batteries over the long run
Sounds like time to search all the nooks and crannies. There's lots of them. My guess is the ATS is below the port bed.
If you have a 30A outlet, make sure that it is also on a 10ga wire to a 30A circuit breaker and that it is a dedicated (nothing else on it) circuit. This does not guarantee that you are getting 30A to the outlet if you are using a lot of electricity in the house (central A/C, electric dryer, etc) or if you aren't getting sufficient amperage to the main breaker. We have a built in surge protector (Progressive Ind.) that not only protects our coach from spikes, but will not allow electricity to come through if it drops below about 110v. We can only run one A/C on 30A.
If you only have 20a available, I would only use it to keep your batteries charged, with a 10ga extension cord.
