No problem running your MES on normal house current . I would try to use a circut that doesn't have anything else running on it.
If you need an extention cord , Go to lowes ,home depot ,etc and buy
10 guage cord and get heavy duty plugs. You can buy the cord cut to whatever length and buy the ends and assemble it yourself.
I made a 20 foot cord as this was all i need to set up my MES where i want it.
