I have a 5hp 230 single phase Leeson motor on my bandsaw. I ran a 30' circuit from a 30amp breaker in the panel to a NEMA 14-30 plug using 10AWG wire. From there, I have a 10-foot 10AWG cord to the saw. The connections are two loads and a ground, no neutral. Every time I turn on the bandsaw, the breaker pops immediately. I checked that the saw turned freely.
I had previously connected a dryer cord to it, also 10 feet long and 10AWG. The connection was two loads and a neutral. The saw ran fine. However, there was no blade so only the bottom wheel had to be turned. The dealer, Laguna, specifies that it is 30 amp. Any ideas how I can fix it?
When I turn on the breaker, I can hear a solenoid clicking. When I turn the start switch, the blade starts to move before the breaker trips.
I went back to the 10-30 cord and my 30amp dryer circuit. The connections are load, load, neutral as far as I can tell looking in the main panel. It works fine. It did take a few seconds to come up to speed. I put the 14-30 cord back on. The connections are load, load, ground. It still has the same problem. I tried the neutral on the new cord and got the same result.
I even read the manual. The spec for the LT18 bandsaw, which I have, is for a 30amp breaker. It also specifies that it has a 4.5hp motor so it may be out of date as it was written in 2008.
I did one more test. I hot wired the plug directly to the breaker in the panel using 10AWG wire I had left over. I got the same result. Could it be the breaker itself? I had previously used it for a 15amp motor and a 20amp, one at a time.
The wiring diagram from the manual. The image says LT16 HD. The manual is for the entire range of their Italian bandsaws.
