Okay, so this has gotten almost humorous the more Ive researched it.
The question is simple: What sized circuit does the Hammer A3-31 need?
So, from calling Hammer, my local Hammer location, the documentation that came with the machine (see attached image) and various folks around the net, the Hammer A3-31 requires a 20A, 25A or 30A circuit. I have heard all three. I have definitely heard a 20A circuit recommended more than any other but it's just hilarious there seems to be no standard.
Where I get confused is when I start trying to logically figure it out myself. You see, in my mind, a 3000W motor shouldn't draw more than about 13A.
P = I * V ---> 3000W = I * 230V ---> I = 13A
And Im assuming even with a motor startup current that shouldnt go over 20A which would be a 65% spike.
BUT, the back of the machine oddly lists 19.8A. Is that listed number supposed to be the highest running current draw? The highest spike for motor startup? Some made up number?! lol Im not sure.
I just can't get past why a 3KW motor would need a 25A or 30A circuit. Any ideas from those with electrical experience would be much appreciated.
