I just ordered an elite with redline 2.2 spindle at 220 volts. the only information I got from redline is the it draws 10 amps. I plan running a dedicated line just for the spindle. whats size breaker is needed for the spindle? 15 amp breaker with 14-3 wire?
thank you
In the Rev 1.1 manual on the Redline website (https://www.redlinecnc.com/_files/ugd/32d749_24e6c9b9c11b42b1bacabccd07fb68d2.pdf), page 33 shows a sticker on the back of the VFD that says 12A. At 80% breaker capacity, 12A would have it maxed out.
If it were me, I would use a 20 amp double-pole breaker and 12-2 wire. You won’t have a neutral, just two hots and a ground. Wires labeled as -3 are 3 wire plus ground (in the US). The -2 wire will be 2 wires plus ground.

Robert has it assuming USA. #12 copper THHN in a conduit or 12/2 copper MC per NFPA 70 (NEC) table 310 but even though the #12 can carry 30 amps it must be breaker at 20amps per section 240-3. I have a 2.2kw also and this is what I did. My answer was EMC conduit on the ceiling from the box, MC Ceiling to the adjacent wall, and the last 10 feet from the wall electrical bit using 12/2 SJ cable. Using SOOW works also if it needs to be a bit tougher extension cord. You might want to use a Nema L6-20 twistlock receptacle and plug. Makes it neater and easier to move wires when cleaning. All available at Home Depot or Lowes. (Engineer, not electrician)
Thanks for that BKurk,
My shop is a steel building with open metal truss, so I’m planning EMC up the wall from the panel and across the ceiling to near the machine and then back down to a box. I hadn’t even thought about a twistlock, love that.
What would be your choice on gauge and breaker for a 110 version? My neighbor is an industrial electrician and I tried picking his brain but he is so used to lead foundries he isn’t much help residentially.
I had figured on 12-2 on a 20A for the spindle and a 14-2 on a 15A for the Masso as I read they should each be on their own circuit.
I’ve got about 3 months to sort it out at this point.
Another consideration, I would include a separate circuit for dust collection unless that is accounted for already/elsewhere.
A 1.5kw spindle should definitely be on a dedicated circuit (wattage / voltage = amp draw). IMO, I would run both lines with a 20A breaker and 12-2 wire. I would do this because I don’t like having any outlet in the shop on a circuit smaller than 20 amps so that if I move things around, I’m not limited on what I may be able to use that plug for in the future. For me, locally, the cost difference between the two (15A vs 20A and 14-2 vs 12-2) is negligible. As BKurk said, I am assuming USA.
Thanks Dean,
New dust collector will be for my birthday in february and will go on an existing branch in the shop that right now powers my router table and jointer. I can’t see myself using either at the same time as the 1F setup.
I need to see what size the feeders to the garage are, I may end up having to bump the whole service up to allow 2 more 20As in there.
Yes you can use #14 with a 15amp circuit and breaker Table 310 again and if you have it an do not have enough #12 I might do it, but the wire gauge is the same for 120vac as 240vac, current is what matters. If you run #12 with a ground you up size the circuit from 15 to 20 by changing the breaker. I you are running new conduit anyway and have the wire, I suggest running 3 pairs of #12 with 3# 12 ground wires. one for the Spindle 20amp 240vac, one for the controls (you may also be feeding a laser, water pump,etc) 15/20amp 120vac, and spare on the wall for a dust collector, vacuum hold down, planer, welder, or any of the the 20 other things that will inevitably come next. I would never suggest doing it because it would violate Table 310 of the NEC, but you COULD if need be swap the 20 amp breaker for a 30amp breaker temporarily to power a welder if need be. The #12 will certainly carry that load for intermittent operation. The 120 twistlock to a power strip would be a L5-20. I also have a Red Iron steel building and I am describing what I did and and glad of it. I actually ran 3 sets of #12 and 1 set of #14 cause that is what I had laying around. (1 inch pipe to a 6inch pull box). I hope it works out for you. I love my Elite Foreman. If you have the QCW table like mine I screwed a 2’ x whatever piece of 3/4 baltic birch to the left legs and used it as a power board. Controller, Laser power, Water Pump control relay, Spindle VFD, power strips off the floor, Dust Collector relays, wire management. Works the bomb. I did need the wider flex track 3rd party addition to make everything work. The folks here were my best source of information and inspiratoin.
Concurring with everyone here, experience below is also US-centric. I went with non-twistlock because two NEMA 6-20 outlets fit in a single receptacle gang (did I say that right? 
). Used 12GA and a 20A 2P breaker.
NEMA 6-20P to IEC C13 cables are pretty commonplace and I bought one of those for the spindle controller.
I have both the compressor and the spindle on the same receptacle and know to charge the compressor and turn it off before running the spindle. The compressor is 60 gallon 175PSI so I don’t worry about running out of air for the ATC.
My outlet bank in this area is a 4-gang with the dual NEMA 6-20 above, a second dual receptacle with a 5-20 and the last two with a 6-50. With internally fused equipment, the 6-50 is also usable as an additional 240v outlet.
There’s never enough outlets. If you have the wall open, put twice as many outlets there than you think you will need. Thank us later 
Amateur hour tip: ChatGPT knows the NEC, but you want to exhaustively check everything it tells you.
