So, now I have these 2 machines which have European wiring as far as I can tell and I'm trying to come up with a reasonable wiring strategy.
i plan on running a sub-feed panel to each machine to power the 5 basinc components that need to be powered.
i plan on using this switch for the 220vac components;

and these for the 110vac components;

i plan to mount all of the switches in this box next to the sub-feed panel with easy operators reach at each machiine;

Now, I'm trying to size the sub-feed panel and this European wiring has me a bit confused
Here are my basic setups
SH-1490
150w reci
1. laser power supply 220vac (28mA or .028A according to Joy at Shenhui)
2. Stepper motor & control power supplies 220vac (2.5A according to Joy at Shenhui)
3. CW-5000 chiller 220vac (max 2.1A printed on label)
4. Penn State 2hp exhaust blower 220vac (8A)
5. Air pump 110vac t.b.d.
SH-690
60w standard tube
1. laser power supply 220vac (15mA or .015A according to Joy at Shenhui)
2. Stepper motor & control power supplies 220vac (2.5A according to Joy at Shenhui)
3. CW-5000 chiller 220vac (max 2.1A printed on label)
4. Harbor Freight 1hp exhaust blower 110vac (8A)
5. Air pump 110vac t.b.d.
Here in the States, I can't find a double pole breaker less than 15A. i had originally planned on a dedicated circuit for each of the components. However, now that seems a bit overkill. Why put a .028A load on a dedicated 15A breaker?
For the SH-1490...
the 2 plugs at the back of the machine + the chiller should be wired to the same breaker. The 220 vac blower could be on its own dedicated circuit. and the 110vac air pump on a third. (3 circuits total)
For the SH-690...
the 2 plugs at the back of the machine + the chiller should be wired to the same breaker. The 110 vac blower and the 110vac air pump on a second. (2 circuits total)
What do you folks think?
Of course, I consider all input as no-binding suggestions by persons not representing professional opinions ;P
I have an electrician coming by on Mon. i just wanted to run it by all you ladies and gents.
thanks
