Rotary Phase question

Ya the stuff is addicting. A little pricey but 1001 uses in the shop.

Well Wdnich your question/post inspired me...!!!! I did some searching last week and picked up a 3P main lug panel and a couple 20A breakers and outlets on ebay. Right now I have 4 three phase machines to run but only two outlets (my mill outlet is hacked/daisy chained off the lathes outlet). I hooked it up this way short term not liking it but it was the easy way out at the time. It will be quite a bit of rewiring, rearranging the shop etc but what I intended all along. So thanks for bringing the topic up and sorry for corrupting your thread!

Btw 12 "spaces" = room for (4) 3-pole breakers. I almost bought a 60A panel with 4 spaces which would only allow room for one 3 pole breaker.

And finally got around to installing the load center and running pipe to each machine. My guess is this rig is way overkill for a simple one man shop but oh well. To the point of another current thread I needed to make use of my trusty 2ton engine hoist to move the lathe out of the way. I measured my voltages phase to phase and phase to ground with only the rpc idling and also under load and looked good.
Also being somewhat anal decided straighten out the criss crossed liquidtite on the RPC at the expense of criss crossing wire internally!

So my little system goes from 60A 1P breaker from main panel to 60A fused disconnect.

That feeds the nema1 magnetic starter/overloads to run RPC

To the Main Lug only 3p panel.

Waitin on the cover panel bought on ebay.
I ran dedicated ground conductor on each circuit to each outlet. Did not run any neutral conductors to keep things simple/separate. I rather have 110 outlets not imbalancing my phases etc.

I have 2 shops, one for metal working, one for wood working. I have been running both rotary and static converters for over 25 years without problems. I use rotary converters for multiple machines as you suggest (shaper with feeder and dust collection). The machines that I want to turn on and off all day long (table saw, band saws etc.) are on static converters. Sliding table saw is 9 HP and runs great off a static converter. Thickness planer is 7.5 HP, static as well. This way I don't need to listen to the rotary all day long.
100 amp line is what I have as well, into each building from the main 200 amp service in the house. Never been a problem.
I do not have separate breakers after the converters, it would be nice, but I don't think you need it.
I do have 3 phase twist lock outlets so that machines can be disconnected easily (code in Mass.)
Good Luck, Larry
all your motors running on static converters are in themselves rotary converters, it must be noisy when they are running.
 
Hi,
I'm new to this site but can share my set up. I run eight different three phase machines from a single RPC. The system is protected by a 40amp breaker. The RPC runs very quiet and I can run all the machines at once so long as I start each machine one at a time.20140901_143041.jpgIMG_0072_2.jpg20140901_092804.jpg20140913_185120.jpg20140901_143026.jpg20140901_143041.jpgIMG_0072_2.jpg20140901_092804.jpg20140913_185120.jpg20140901_143026.jpg20140901_143041.jpgIMG_0072_2.jpg20140901_092804.jpg20140913_185120.jpg20140901_143026.jpg20140901_143041.jpgIMG_0072_2.jpg20140901_092804.jpg20140913_185120.jpg20140901_143026.jpg

Your system is very neat and professional looking; I'd be embarrassed to show mine
 
Nice shop. But wayyyyy too clean!:grin:
