Can I Remove Male End of 30 Amp Electrical Cord and Replace with 50 Amp?

Question: Hello, I had a 26' Jayco travel trailer for years. I had electrian install a 30amp outlet in the garage and a 60ft extension cord. Used it when TT was in driveway just to test A/C in spring and run refrig the day we packed for a trip.

This year I upgraded to a Komfort 5th wheel. My question is can I remove the male end of the 30 amp cord and replace it with a 50amp so I can plug directly into side of RV?

I am trying to avoid plugging in 50amp cord and then using addaptor to reduce down to my 30amp extension cord.

The 50amp adaptor is clearly markd Grn, Blk,Wh and red. Is it ok to use the gr, blk and Wh wires only and use it that way?

thanks you in advance for your time,
New York

Robbie: NO, you cannot change a 30 amp plug to a 50.

A 30 amp cord uses 3 wires and a 50 amp needs 4
You can buy adaptors that allow you to a 50 amp cord into a 30 amp service "safely" at any RV Parts supply store. Please note the key word here is safely.

I would never suggest you cut a end off any cord anyway. These are water tight molded ends and an replacement plug is not.
