- All RP drives are 3 phase, as is the RM05. All others are single I'm reasonably
- sure. The TU/A 77/78/79 are also 3 phase I suspect...
-
- The 60/70 only is a good guide, but not concrete. A large factory config well
- could have a 3 phase power controler.
-
- Look out for in-rush / strartup currents with some stuff, ie 70 amps/phase on
- an RP07 spinning up. This can pop fuses that will be fine under running
- conditions. The way the lights go OUT is a good converation piece too!!
