Today, I looked at a 16" DeWalt radial arm saw. The motor is clearly marked single phase, 3HP.
The owner said he had it rewired and checked over 8 years ago and it has sat in his shop ever since. The shop is a commercial building.
As I said, the motor is clearly marked single phase, but there is a newly added (8 years ago) electrical box under the saw. It also says something about single phase on it, but I could not make it out. The plug however is a four prong twist lock and clearly states it is 240/460 Volt, 3 phase.
All I can guess is that the shop is three phase, and that the electrician somehow wired the three phase plug into the new box which magically turns it into single phase at the switch or motor.
I have wired my desert cabin from scratch, and done remodels, but I have no clue about three phase wiring. Is this something that could have been done?
The saw runs fine at his shop.
Thanks in advance,
Rick
