I ordered a new 350P last Wednesday (supposed to be here Monday) and I wanted to go ahead and get the electrical done. I went to the Miller site and downloaded the manual and here is what it says.
Input voltage 230V
Input Amperes At Rated output 61
Max Recommended Standard Fuse 90
Min Input Conductor Size in AWG 8
Min Grounding Conductor Size 8
Now if I didn't know better, I might have used a 90 amp breaker with #8 wire. Why would Miller put something like this in the manual?
I know that they are saying the you can use a "MAX" 90 amp breaker and a "MIN" #8 wire, but they don't tell you that if you use that #8 wire you need a 40 amp breaker or if you use the 90 amp breaker you need to use a larger wire (#2 maybe, I'd have to look that one up)
I used #6 from the box to the outlet (about 35') and I'm gonna make up a 50 foot 6ga. So extension cord. I already have a 70 amp breaker and some of the charts that I have seen say the the 6ga will carry 70 amps. I will buy a 50 or 60 amp breaker if you think that is necessary.
