Before you start trying to put a 30 amp RV outlet in your garage let me ask you a question.
Have you ever installed a 15 amp circuit? If the answer is yes, then read on, if not Hire someone who is licensed.. And have them put in a 50, not a 30. Explanation follows:
Now: the TT-30 install
The job is identical to installing a 15 amp duplex outlet with the following differences.
Different outlet (TT-30 instead of Duplex 15)
Different wire (heavier, 8 or 10 ga depending on the run)
Different circuit breaker (Like the wire, 30 amp instead of15)
That's it. Otherwise it's the same job. both are 120 volt outlets. both hook up the same way (Black wire to copper screw, White to Sliver, Green/bare to Green) That's all there is to it.
Now: If you have to hire it done why have 'em do a 50?
MANY stories about folks who hired an electrician to install a 30 and the professional wired it wrong and burned up the electronics in their trailer.
If he puts in a 50, this almost never happens.(Not one story to date in the years I've been reading forums)
PLUS the cost to upgrade, when you upgrade, is zero.
