After reading the last thread about using aluminum service entrance cable versus copper, I know that the general consensus is that aluminum is fine if installed properly with greased termination points and such.

What I am wondering is if it would be ok to use aluminum to hook up machines such as a 50amp sliding table saw, 30amp shaper or a 50amp dust collector ect. I would assume so, just curious to know what you guys think.

I was mapping out my upcoming electrical overhaul at my shop and I have some long runs with several large machines so it would save me a lot of money to use some aluminum wire. I am having to pay an electrical engineer and an industrial electrical to do all of this so I will definitely run it by them too. My shop is shaped oddly and the best spots for my machines are often not close to my panel. Well about half are and half are not.
