Best to get an electrician. I'm a builder/remodeler but when it comes to 440 volts I leave it to a pro.
440? Im gonna say he aint got 440 outlets around his house.
For instant results you could get you a GOOD extension cord and steal the washing machine receptacle for a few hours. I think they normally are 20-30 amp breakers and should be dedicated if in a modern home.
And i always try to throw a GFCI plug in the mix just to be extra safe.
