Power cable "Break in" question

I have an integrated amp on order and expect delivery around the end of October. I decided to go ahead and purchase a good power cord. Considering I had to sell my existing amp to finance the new order, I'm left with nothing.
My question is; Can I simply plug the new power cord into the wall to register some break in time?
I like to plug in multiple devices. A refrigerator demands higher current but only runs sporadically. A lamp draws continuously like an amp operating (but without fluctuation) or on standby. I make no guarantee that my method is beneficial. It is just what I do.

I have a "Y" version of the device Jea48 recommended. It allows me to plug in two power loads but a power strip or other outlet-multiplying adapter would work just as well. By using multiple adapters I have daisy-chained multiple power cords together to break in more than one at a time.

Good luck and I hope you enjoy your new amp.
Wow! It's definite example of peak enthusiasm -- Getting aftermarket power cord before the amp arrives and make sure it's 'cooked'.
You can also connect it to DeWalt battery charger so it always will be under the small current going through.
Since I generally buy a lot of new gear at once, I just let all the gear burn in at the same time. At the moment, I am burning in my new Vitus SCD-025Mk2, Jorma Statement sc's & Gigawatt power conditioner. I also have the option of using my Isotek Full system enhancer cd to accelerate the run in process, though I generally prefer to play normal music and let the natural process take it's course.
