Shore Power Again

Okay I have searched but don't see the exact answer I need or maybe I missread.
In the rear of my garage is a single 220 volt receptical that is wired on its own circut from the breaker box. If reading other posts correctly, is it okay to buy a 30 amp breaker to replace the one used for the 220 volt. Then replace the 220 volt receptical with a 30 amp receptical? From reading other posts it (30 amp) needs to be on its own circut.
thanks in advance for infomation.

James,

If you are not using that outlet for anything else, you can change it from 220V to 110V. But, unless you are absolutely sure of what you are doing and comfortable working inside the main breaker box, call an electrician.

I am comfortable enough to change out the breaker and receptical.
So is that the answer to my question???? Since it is a dedicated circut I just change those out?
thanks

I have a 220 V. outlet to run an air compresser in the back of my garage as well. I branched off one leg of the circuit and wired a RV outlet and box at the front of the garage. No problems in almost 8 years.
With the GT living just outside the door I've got lights, heat and A/C whenever I need it. I wasn't worried about the breaker in the house as the coach is protected by it's own breakers.
During the Holidays the lights and timer all connect to the outlet which has eliminated a big headache with the rats-nest of cords.
Go for it. Even if you have to run conduit like I did it was an easy job and has made life much easier working on the old girl.
Now, if I can just run a pipe out to the septic......

Tom.

Yep,

To be 100% sure.... Some systems in an AS trailer are 120 volts alternating current. There is nothing on the trailer that is 220 volt current.

Hi James, You can do that. You can use the same wire as long as you don't connect one leg. Read this here it sounds like what you what to do. Becareful 220v will kill you.

James,
the dedicated 220V is all wrong for you trailer. 220V will fry everything. It needs to be 110V dedicated 30 amp.
A 220V dryer outlet and a RV outlet look a lot alike. They are not.
If you take the 220 which is two hots and a ground and hook it up as one hot and two grounds then you will have 110.
Of Course the breaker will have to changed.
You will have to consult the documentation on which blade is hot.
If you have any problems with any of this hire an electrician.

there is more involved than the breaker and the outlet assuming you can wire it properly.

the wire needs to be the correct size, 240 volt circuits can have smaller wire due to the higher voltage and lower current.

plug your distance and 30 amps into this caclulator and compare to what you have for wire. then go ahead with your project.

thanks for all the input. I am going to contact a neighbor friend as he is a certified electrician. I shut down the main power and removed the cover to expose breakers and got in there and thought to myself that safe is better than sorry. Thanks again for all the information.

Be careful!!! one of those hot legs may be a "stinger"!! I think that depends on some sort of line connection.
You have input on this john hd?

[john hd]

i think james has the situation well in hand if he has a certified electrician.

james,

make sure you tell your electrician friend that your trailer is 120 volt ONLY!

no matter what he thinks the plug looks like! there are more than a few members here that have had an "electrician" wreck their trailer electronics by mistakenly connecting it to a 240 volt circuit! even with the correct outlet!

That's pretty interesting. If you plug in 60 ft of wire and 30 amps, it calculates #8 wire for 120 VAC, and #12 wire for 240 VAC.

I had no idea there was that much difference.

[john hd]

twice the voltage half the amps, that's why they call it a law!
