#electrical Shopping list for ceiling drops
#electrical
I'd like to keep this thread tightly focused on a proposed shopping list (and preferred retailers) for ceiling mounted electrical drops to service 3 phase machinery. The assumption here is that the supply is #8 THHN wire in 1-1/4" EMT, with a 10/4 cord feeding the machine.?
Specifically, I'm looking for suggestions regarding the box/enclosure, preferred method for connecting the THHN conductors to the 10/4 cord (wire nuts or blocks), and the strain relief parts.?
Photos of existing installations would be welcome as well.?
I'm finally at a place where I can install a more permanent wiring solution for my shop, and would like to run the 3 phase on the ceiling, with drop locations above and slightly to the side of each machine.?
Thanks,?

Re: 3 phase power plugs/outlets
I don't know the specifics of those machines.
Yes, the "manufactured" leg is the "high leg".? Brief summary of the issue here.
We typically refer to the three phase conductors as L1, L2, and L3.? Assume L3 is the manufactured leg.
1) Motors only "see" the voltage from one leg to another, so it sees three voltages:? L1:L2, L2:L3, and L1:L3.? In an ideal system, these three voltages are 240V.? Note that there is no "high leg" here from phase-to-phase.? ? Normal utility supplied power is "ideal", as is a Phase Perfect converter.? Rotary phase converters are not ideal, and you will see some voltage variations between L2:L3 and L1:L3.? However, on a quality commercial (vs home made) rotary, the variation will not be enough to bother the motor.? So machines that only have motors and simple switches are unaffected by how the legs are connected.? ?I
2) The "high leg" is not a reference to the voltages between the 3 phase conductors, but rather to the voltages from a phase conductor to a neutral (if present) or to ground. Since motors don't use neutral or ground, this doesn't affect them.
3) Some things other than motors, most importantly electronic controls, can be sensitive to voltages out of standard range.? ?So on machines that have such things, you want them to be connected to L1 and L2 (these components don't use all 3 phases)? Hence manufacturers identify which of the phases are good for controls and which are not (ie, say connect the manufactured leg to brown, etc)?
|
Re: 3 phase power plugs/outlets
I hope I¡¯m not hijacking this thread but I¡¯m currently trying to sort out the line connections on several 3 phase machines running off of my 20HP Phoenix rotary phase converter . For the record i¡¯m a complete three phase dummy.?
?I just commissioned a new k700 and the instructions specified that the manufactured leg ( i assumed this to mean the high leg from the rotary converter) to the brown wire on the attached power cord. This prompted me to double check the placement of the manufactured leg on my 2004 RL160 collector, 2000 F700Z shaper and 2008 Exact 51 planer. Can anyone help me determine the correct placement of the manufactured leg on these machines?
Thanks, Chris

Garrison? This drill press is pretty handy could be better at the moment the turret has issues so I use one spindle and a Rohm hand chuck.? I have 4 speed options ,high / low ,,, turn machine on ,,,start to move large spider handle,,,start in slow ,,, so normally do nut use center bit just let bit find center than if small diameter select by switch high speed and drill. When done raise quill back up drill shuts off. I use a low profile German Rohm vise and is mounted to a Thompson 100 xy bearing copy table . Both axis lockable manually or with electric brake . Very handy table i use 3 of them on different drills. Also set up with foot switch for instant reverse for tapping.? Machine is Japanese one of last made .? Currently setting up rise and lower of head when out of stop set tange with 12 v DC gear motor from wheel chair and chain drive . Vari drive. Head moves on 2 -60 mm shafts 10¡± center.

?My prior drill press, a Powermatic

mechanical variable speed with digital readout
was nice. ?It was not too powerful, which was
good, but my larger Forstner drill bits did not
stop rotating when cutting wood. ?However, I
wanted a radial drill press where the table
stayed fixed and I could drill holes farther
from the edge of the wood, and I could adjust
the distance chuck to wood without the table

I went with a 3 phase vintage Delta

with a smaller motor - a 0.5HP 1725 RPM motor..
?A VFD was added. ?This was discussed in a prior
thread. ?
The VFD makes noise at all times unless the
power supply is turned off, and the larger
Forstner bits stop turning in wood, especially
at lower speed.
Plan is to change to a ENC single phase 220V VFD
along with a Marathon 1 HP 1750PRM 3 phase
motor. ?A friend has a similar radial drill
press but no VFD and does not have this issue.
He would have to change belts to adjust speed as
the tradeoff. ?I am hoping the upgrade will give
me the needed performance without the need for
belt changes.
When the change is made, I will provide feedback
on the performance.?

Re: 3 phase power plugs/outlets
Mark,
I was merely saying that the following statement is wrong:
¡°It takes voltage in that is 180¡ã phased, and shifts to 120¡ã phased¡±
No phase converter does this. A static converter (I doubt anyone here uses one) does create a phase shifted (delayed) signal to start a 3 ph motor but it still does not take 180 deg phase voltage and shifts to 120 degrees.
