I'm wiring my new shop addition!

[kurt_rose]

I'm building it just to house the Bot in a room of it's own. Can someone tell me the power requirements to run a 48/96 Shopbot? I'm just looking to get everything prewired and was hoping to do it once while I have the walls open. I know I'm going to put in 2 30A 220 lines for dust collection and possible vacuum in the future but I'm not sure about the Bot itself. Thanks in advance, Kurt

The answer is "it depends"

Are you planning on using a 110 volt PC router or a three phase spindle?

[kurt_rose]

Sorry Ken. I'm most likely going router seeing funds are tight but I have no issues wiring for both for future upgrades. It's just easier to do it now for both. Just trying to cover my bases and make everything plug and play.

[ken_rychlik]

I would do 30 amp 220 with a disconnect there. Run an extra large conduit and leave a piece of string in it to pull wire. Then you can pull whatever you need as your needs grow.

The safe way to know for sure is to ask shopbot what you need for the unit you will be buying.

Don't forget about power for a vacuum system now or in the future.

You may want to think about adding a couple of 110 outlets for ancillary equipment like computer/vacuum/lights, etc.

Follow Ken's advice

The main work will be running the conduit.
I would also consider adding a sub panel and expand from there.

You should really put in a shop dedicated sub panel with 60-80 amps. Even of "all you are running is the shopbot" this will give you the ability to seperate the breakers for the controller and computer, spindle or router, and hold down vac and dust vac as well as the shop lights, air circulation fan, space heater, radio, or whatelver else you discover you will need or want once you get things set up.. The more seperation you have the less likely it is you will have electrical interference messing with your cutting files. Running a conduit with additional room is always the right thing toi do. Easier to do that now than have to "double up" later. Last time I did this for a friend we ended up putting in a new main panel. He complained about the upfront costs then and thanked me 3 months later.

a need a 100 amp with it own panel

[kurt_rose]

I already have a 100 amp panel in my detached garage being feed underground from a 200A in my house. The garage is 24x24 with the new addition being 12x24. I have plenty of space for new breakers and the run to the Bot will be only 10' from my panel. Do you guys still think I should install a sub panel? Will I get noise from the other equipment in my shop?

I am an electrican by trade. If it was me I would put in a little 100 amp 12 circuit sub panel. run 4 wire wire to it. two hot , one neutral and a gournd. I also put in a ground rod at the sub panel just in case for noise. the reason behine this is. you can put in the proper breaker and if one should trip you can reset it their. also you can trun it off when not in used. I have a sub panel for my bot even those it only 30 feet from the main panel. I trun the main off when I leave just in case of lighting or a back feed. you don't have to feed the panel with 100 amp cable nor put in a 100 main. 60amp main should do with number 6 wire.

hope this help.

If it is only ten foot away, you can wire direct into the main panel and I would not worry about another ground rod and sub panel ten feet away. Just a 30 amp 220 circuit and a few outlets near by should do you fine.

[kurt_rose]

Thanks for putting up with a noob guys. I'll get it done this weekend!

[bleeth]

With the info that you have a 100 Amp underutilized panel so close I will also agree with Ken that you just need to run your properly sized lines to outlets at the machine. I like a dedicated breaker for spindle, a dedicated breaker for computer and control box, and from there you can piggyback your dust control, holddown, extra outlets for other stuff, etc. I believe in "Commercial" size minimum breakers as in 20amp for any 110 and 12/2 wire.

By the way Kurt, I have a friend living near me with the same last name: Bruce-any relation?

[kurt_rose]

Thanks dave. As far as Bruce Rosenzweig it doesn't seem to ring a bell. My Father came from a family of 10 and I have never met a couple of his brothers so you never know. It's definitly not a common name.
