Jim is correct. We've had reports over the years of licensed electricians wiring 30amp outlets for 240 volts.

There's just too many who are not familiar with RV electrical service, owners, well meaning friends and "professionals".

True, True, oh how True!
Sometimes the 'expert' electrician doesn't want to listen to the 'novice RVer' when it comes to wiring an outlet for an RV.

As someone said,... "Trust, but verify"!

Keep this in your bookmarks: installing and understanding 30A and 50A RV wiring. It otherwise gets confusing quickly. The 3-prong, 120VAC, RV receptacle appears identical to a 3-prong, 240VAC dryer receptacle, but is wired differently. Notice a 50A RV receptacle is 240VAC (identical to a 240VAC-4 prong welder/dryer receptacle), the entrance cord into your RV and into the AC breaker service panel also carries 240VAC. The breaker service panel is designed to keep each 120VAC leg separate so you only have access to 120VAC for the breakers.
All-electric motor homes do have a breaker service panel that allows 240VAC circuits in the coach.

Sorry Ray, they are NOT identical. Glad you said "APPEARS" but they are NOT the same and won't fit each other.

I don't believe the 50amp RV recpt is the same welder and dryers either. Take a look at a products catalog of a manufacturer of electrical devices. Recpts of DIFFERENT voltages and/or amperage are NEVER interchangeable.
It IS however possible to install the wrong device on the end of a cord that then requires the wrong reecpt to plug it in to.

As said earlier check the microwave for a fuse. Mine had 2, one accessible from the outside and the other was hard wired in side inline with the power cord. Pain to open it up, but it cost less than $5 to fix rather than several hundred to buy one that incorporated a hood fan and fit in the smaller space of an RV.

You forgot to highlight the rest of that sentence where I said: " but is wired differently"

Open that link. Now go to the 50A link in the left column where it says: "This 50-amp service has 4 wires with two 120-volt HOT feeds. It is a misconception that this 50-amp RV service is something special. This service is a STANDARD 120/240 50-amp 3 pole with 4 prongs used for numerous applications."
