The simplest way to ascertain if 240V is powering a receptacle is to read the embossed print on the face. It will denote which model it is and the prong receptacles will only accept the correct plug.

All recepts., switches, etc. are required by UL/NEC to have the voltage that they are designed and approved to be used at embossed on the device. Judging by the number of "my electrician fried my RV" posts every season, many electricians apparently can't read which is frightening! I wouldn't assume voltage at a device is what it says it is rated for as someone could have mis-wired it. A voltmeter is a really good tool for any RV-er to have.

I've seen more than a few tradesmen that operate on association with what's been done before. I think a few just see a large three slot receptacle and assume it needs to be 240V. Really, no excuse for miswiring the receptacle.

Yes, a multimeter is a "must have" to maintain and repair an RV. That, or a wallet with cards. ;)
