WOrse comes to worse, remove the plug and cable and then hard-wire it. If you needed it to be portable, it's not a huge job to switch back. Wouldn't want to do that every day, but once in awhile, probably not a big deal.
Note that high current sockets may not work all that well if you constantly insert and remove a plug into them. The high current does raise the temperature of the contacts/prongs, and over time, the contacts start to lose their tension. WOrks much better to just plug it in and leave it, so that brings you back to hardwired as being preferable.
