New Shop power setup requirements

[digitalwoodshop]

I am getting ready to finish the inside shell of my 16 x 24 wood shop. I have been searching the forum looking for power requirements and grounding for the ShopBot. Can I get some suggestions as to how many and what kinds of power I should pre wire for now that the walls are still open. I liked the idea of the individual blower vacuum motors mounted under the table for hold down and want to plan wiring for that too. I just finished a 14 x 6 foot addition on the back of the wood shop for dust collection equipment. I have a 200 amp service in the Laser Engraver shop with a 100 amp sub panel in the wood shop. No 3 phase in my area. I am a one man shop and have installed current monitors on the main power panel to keep an eye on my Amps. I am about a year away from buying a ShopBot, I am not sure if it will be a spindle or router. I ran CAT5, CCTV and E Stop wires between the side by side laser shop and the wood shop as I will share time between the buildings. I liked the suggestion to run a stripped down computer for the ShopBot, customizing the operating system at install. How about Earth Grounding the ShopBot? I didn't search that but I wonder about ground loop? If I ran copper back to my main service ground rod that might work... About 40 feet. Trying to get it right the first time.

Start herefor grounding,and then look at this as a start for your power needs.
After reading these, come back if you have more specific questions.

Now is a good time to think about how many circuits you should use. I recently did electric on my new shop, and installed these circuits;

1) 20 amp for controller/computer (with battery backup, incidently)
2) 20 amp dedicated for router
3) 220V 20 amp for dust collector

The controller is on a dedicated cirucit- that is nothing else gets plugged into that circuit- so that a failure of some other tool or machine won't cause a breaker to trip while the SHopbot is running. Same thing for the router- its the only thing on the circuit.

This is working very well so far. Others will add to this, no doubt. Wire what you need now- its way easier than retrofitting.

After a year of owning my ShopBot, I moved into a new 16 x 22' shop. I had a 220v installed in the ceiling above the ShopBot and one on the wall for the dust collector. When I dropped the 220v to a seperate breaker box on the ShopBot, and from this I also wired a 220v extra outlet and a 110v duplex outlet mounted on the table's XY leg. This allowed an additional shop location for 220v, and a 110v outlet for the router.

In addition, I put split duplex 110v outlets on the walls in convenient locations. The outlets are split between 2 breakers, so I will never overload any single set of outlets with many tools connected

I have never had a grounding problem without using a special earth ground.

Mike, Wayne, and Tim,
Thank You for your reply's. Some great reading in the "check here", Thanks!!!. I read the forum about once a day had have been for months. I especially like the troubleshooting as I am a retired Navy Technician and worked for Sony for 8 years in everything from making picture tubes, keeping the line running in San Diego to Fixing Play Stations in Philly. We had a lot of Fanuc robots, Servo and Stepper equipment in San Diego.
