I am building a home and want to put an external 30 AMP Power plug so I can plug the RV in while it is in the driveway.

My electrician asked me what voltage I need 110v or 220v. I looked thru my Adventurer owners manual and can't seem to find it a reference.

Anyone know the answer?

RV's are powered by 110-120 VAC. Your rig needs a 30 amp circuit added to your 120 VAC panel.

I'm adding one to my house after the spring thaw. Right now there is 18" of snow between my driveway and the electrical panel around the corner of the garage.

You might show the following to your electrician. It may be a little elementary for him in some areas, but will make it very clear what you need, and what the plug should be. For instance, it is NOT the same plug as a 30amp clothes dryer. And it is important that the polarity be correct.

Note: applies to following:
Copyright 2002, 2003 Steve Das

125 Volt, 30 Amp AC Wiring

30 amp RV service can deliver approximately 3,750 watts (125 volts X 30 amps) to the RV. The 30 amp RV receptacle is a NEMA TT-30R. The receptacle is usually marked "Travel Trailer Use Only". The matching plug is a NEMA TT-30P. The receptacle is wired with three wires from the breaker panel and requires a single, dedicated 30 amp breaker. The three wires are one 125V (black), a ground (usually bare or green) and a neutral (white). The terminals on the back of the receptacle will be marked with G (and perhaps a green screw), W (and perhaps a silver screw) and maybe B (and perhaps a brass screw) but in many cases, the last terminal is not marked. The bare/green ground wire goes to the screw that attaches to the metal frame of the socket marked 'G'. The neutral goes to the side marked 'W' for white and the black hot wire goes to the remaining screw as shown. Before using the outlet, make sure you check the polarity with a tester.

If I was building a home I would ask for a 50 amp service for my RV. Let's face it, one day you might get something bigger and that 30 amp will just be under rated for you.

Have your electrician put the 50A connector outside and buy yourself the 30A - 50A adapter plug. Most people will buy bigger and better RV's as they "move up" and 50A is the bigger one. This is a sound choice as you'll have room to expand.

This is what I did when I refinished the downstairs. The minimal cost difference now is well worth it! Good luck to you.

I agree with Bill N.Y. but would recommend having the electrician only wire one of the two hot legs to a 30 amp circuit breaker. This way you have the correct overcurrent protection and will not risk overheating the power cord on the RV if you had too many appliances turned on at once. If and when you go to a coach with 50 amp service then have the electrician swap out the single 30 amp circuit breaker for a two pole 50 amp and wire in both hot legs and you will be good to go for 50 amp service.

Don't forget to make sure the electrician provides wire good for 50 amps, that way tou will not have to replace the wire.
