Question 30 amp box

I am considering putting in a 30 amp elec. box so that I can run the AC when visitors overflow at the house. Can this box be mounted on an inside panelled wall in my garage or should it be mounted on the outside of the garage brick? While I know that an electrician should do this, does it entail anything more than running the correct size wire from the fuze box, up the wall, across the garage attic, down the panelled wall and to the new breaker box? Craig

If someone else does not reply to this with the correct answer, I will in a day or so. I have acquired 2 30 amp RV hookup boxes that each came with 150' of heavy cable. These were used at a church here in town for traveling evangelist and they no longer supply this service or used the hookups.

I have my favorite electrician coming by any minute to see if I can pull this cable to my service panel. I plan to put these hookups and either side of my house so that I can store my TT on one side or load/service it on the other. Want him to assure me that these will pass code.

Craig. An exterior box is Ok as long as it is intended for exterior use. Running that much wire, as you described, I would make sure that you use an adequate size wire, probably 8 gauge if not 6 gauge. It's a function of total length. Andy

I have done this and it is eaisy> Like andy said use the right type of wire and but NAME BRAND components. Leviton, etc. The cheap outlets will berak and then you have a loose connection.

I love being able to fire up the AC while I am working in the coach under the Florida sun.

Thanks Andy and Brett. Bobby, let me know how your installation turns out and the type of wire (gauge and length) you run. Craig

Adding an Rv electrical outlet

Adding a remote RV outlet is very easy with some planning. Things to be considered in the plan are, amps of new circuit, new circuit breaker box and RV receptacle, length of new wire run, and location of out door equipment.
Some breaker boxes and receptacles are indoor or out door. It has to do with rain tite. Usually if a new electrical run is greater than 50 feet, a new circuit breaker must be added to the power source box. The power should be able to be controlled at the power source and at the user location. If possible, out door equipment should be protested by location or an enclosure. Collect all the information with a drawing and any special circumstances and talk to an electrical contractor or an electrical supply store. The electrical power needed is 30 amps at 120 volts AC. This requirement would indicate the use of AWG #10. A wire run over about 80 feet would indicate the next wire size larger, that would be AWG #8. I certain areas, the wiring may need to be in conduit of a correct size. Frank

Hammer drill a hole through the brick wall and mount a exterior covered 30 amp outlet. That way it will be a clean job. If you should ever get rid of your Airstream (heaven forbid) you can always change it to a regular 20 amp receptacle.

I picked up a 30 amp box at Camping World and am now waiting for the electrician who will be working on our new room addition. I'm also going to be running a long run 50 amp circuit to the far end of the house for a point of use water heater for our master bath. These two new circuits look like they will demand a secondary panel as we are reaching capacity on the old one.
At least the run to the outside box will be short as the driveway is on the service side.

Here is a handy wire size chart:http://www.nwes.com/Wire%20Loss%20Tables.htm

Looks like 65 feet is the limit for a 30 amp circuit with #10 wire.
