Question Dryer Circuit to RV Circuit

My son has an extra Dryer circuit at his cottage on the beach which I would like to convert for use by my motorhome which requires 30 amp service. I have the special 3 prong plug that is needed to convert but am unsure how the wiring must be altered.

I tend to believe that your Rv is running on 110 volts,,,, is this true?

RV Circuit

The plug is a 30 amp but must have 120 to 125 volts in it. Not sure, but assume dryer circuit will have 4 wires. Should I drop one and which one? The new plug is a female 3 prong 30 amp/125 volt.

An old dryer could be 3 wire. It can be done but I not sure how the code guys would feel about it. If it was 4 wire you could eliminate one of the hot wires,, the red one and would need to have the breaker in the panel changed to a single pole. For my job I would run a new wire, 10/2 wg,, put it in the most convenient and safe area.

Most dryer circuits installed prior to 1996 do not have separate grounding and neutral wires, which would be required to get 120 volts. If this circuit was installed after 1996 and has a receptacle with four holes, then this can be adapted. Was the cottage built since 1996?

If the cottage was built prior to 1996, you may still be able to convert this if you replace the double-pole breaker with a single-pole breaker, or if you simply move the white wire off the breaker onto the neutral bar (if indeed there even is a white wire on the breaker).

There's a really good chance that you will be better served and safer if you install a new circuit for this purpose.

If it was 4 wire you could make a legal install,,, 3 wire , no,,, If you change wire or add one like I said,, make it like you want it,, the recept needs to be somewhere dry when plugged in or one of those approved covers.

I am almost positive that the plug is a three prong now but I do not know what year the cottage was built. My guess is before 1996. Here again, we are talking Galveston Island and at the far west end. Not sure what codes existed.

So the only way to do this is to convert this circuit to a 120-volt circuit at the panel, and then change the receptacle to a 120-volt receptacle. Or leave this alone and install a new circuit. The latter would be my preference if there is room in the panel.
