Plugging into house current

inlyzbldcj · 04-30-2021, 03:33 AM

Getting ready for a trip and want to know what is the best way to plug my thor hurricane 34J into my house current so I can cool off the fridge before a trip for water and soft drinks....can I run my 50amp cord to an adapter that will plug into my extension cord from my garage, or, do I need to plug in the 50 to 30amp adapter then to the 30amp to 110 adapter? Or should I just turn on the generator and inverter for the fridge for a couple hours before we leave to cool it off.

I would just do the 50-30-110 adapter, I have done that several times with no issue.

I regularly plug into a 15amp circuit in my garage
I use a standard “30amp to 15amp” plug.
You can reduce from 50 to 15 if you desire.
But just be aware that you can’t power much of anything from a 15amp circuit. Especially if you add standard extension cords to the line.

Some RVs do not like being plugged into a GFCI protected circuit

I have a 50amp breaker installed for my hot tub....could I also get a plug in and another 50amp breaker put in the box for just that plug? I mean is that possible? So, it would be like I was plugging into shore power at a park.

I had a 50 amp done that at my house and its really convenient. Just make sure that you electrician knows that this is going to an RV. It's really a split 120V service. I have heard stories of electricians mistakenly wiring it as 240V.

Why do I feel that you are asking if you can connect to the hot tub circuit? No you cannot do that, but yes you can wire in your own RV 50A receptacle from the main breaker panel... if there is room in it for the breaker. As mentioned by Newf026, it has to be a 120/240 circuit.

Because it is 240 VAC service. The problem is ignorant people (some electricians resemble that remark) that wire an RV 30 amp 120 VAC plug for 240 VAC.

An RV 50 amp 240 VAC service is a STANDARD configuration used by many 240 VAC appliances.

Aren't there any "50 to 20" adapters out there?

Yep.

It is 240v for 50 amp

The confusion is over 30 amp services

Absolutely

My newer welders, car charger, hot tub and so on all have the same receptacles

Some car chargers use the 14-50 plug like RVs do; sometimes the electrician installs something like a 6-50 which doesn't have the neutral and thus won't work for a 50a RV (or a 30a for that matter).

Yes you can get another 50 amp breaker and plug installed.

At the sticks and bricks we have a spa and it runs on 220 50 amp. We also had a 30 amp plug installed when we bought a class c a number of years ago which was a mistake because I then had that changed to 50 amp for the Challenger and everything except the metal box had to be changed. Should have went 50 amp to begin with.

If you have the resources get an electrician to install an RV 50 amp plug. You'll be happier in the long run.

In the meantime - 50-30-110, turn on fridge, cool down drinks, unplug and enjoy the trip.....

We are pretty fortunate. Our RV is on the side of our house and I have 30 amp service to it. I live in Florida and I have my AC ON all the time set at 75. Before camping turn the fridge on couple iof days before load up. When we get back from a trip. AC on fridge on. Take our time unloading.

lwmcguire · 04-30-2021, 05:52 PM

Everything varies a bit by local code interpretation

All my newer high amp equipment has 4 prong plugs and should have a ground, of course they work fine without

Given I have been around a long time I survived as did everyone back in the day without ground wires

Most folks get into trouble trying to run their RV on a 15-20 amp outlet combined with a 14-16 gauge extension

If you need an extension use 10 gauge or larger

My 30 amp service is with the 3 prong RV plug. 10 gauge wire with its own 30 amp breaker.

This may help. You will need a 3 conductor with a ground to wire an RV 50 amp circuit. Most strictly 240V circuits (hot tubs, home AC’s, etc) have 2 conductor with a ground. Since RV’s are 120V, you need 3 conductors (2 hot wires and one neutral wire) along with a ground so your RV will have 2- 120V circuits. This is similar to your power panel on your home, each side of your panel is 120V (but 180 degree out of phase with each other).
If you measure each hot wire to the neutral it will read 120V, if you measure across the hot wires it will read 240V
It is important if you install a 4 wire 50A receptacle to assure the wires are landed in the correct location to avoid having one of the hot wires landed where the neutral goes which would light one of the 120V sides with 240V.
