    It may be a silly question, I am looking for advice on but hopefully not.

    My old range broke, dead as a doornail. I got a new range.

    The issue is as such, the old range, and the corresponding outlet was 30amp, 3 prong, the new range is 40-50 amp max, 4 prong.

    My breaker for the range is 50 amp, the line in the wall, so far as I can tell, is ok for the 50 amp.

    If I change out the 3 prong 30 amp outlet to a 50 amp 4 prong will this work? Or am I asking for trouble?

    I am obviously not licensed, but I am tech and electrical savvy enough to switch a wall outlet out without killing myself.

    The real important item is the size of the wire from the breaker to the outlet. Since the original is 50 amp breaker the wire is probably 8 gauge copper. however, it will only have only three conductors. The new outlet may read 50 amp but that is the MAX rating and it will work, if you have four conductors.

    Is this a free standing range? Did it come with a power cord already install? What is the brand and model number so someone can look it up for you?
    Look in the installation instructions for the range. There maybe instructions on how to convert to three wire.

    Here is a typical installation instruction for a range that can be wired as four wire or three wire. Most likely you will need a new 3 prong outlet with a 50 amp rating. And a new three prong cord for electric ranges. There is a difference between ranges and dryers.

    Ran across a similar issue during upgrade of Oven/MicroWave wall unit. Installer was going to tie Neutral/Grnd and I didn't like that idea so I went ahead an ran new 4 wire feed to accommodate new appurtenance.

    There are millions of homes where it would be very difficult and expensive to rewire, especially with homes on a concrete slab.

    Yes, very true on expense etc for mega amount of homes on running new circuit. The old set up on my original Oven/Micro Wall unit would work OK on the upgrade, however I lucked out to have another option. Thanks for git back.
