I would have go guess that from the existing panel to the new panel is probably no more than 40 or 50 feet. As mentioned, we haven't closed on the home until next month.
Because this was a model home and the homeowner never took out the realtors office "which takes up part of the 3 car garage" there is already electrical plug in outlets in there. I would say that I'll have about 15-20 regular outlets. The lighting for the shop are "eyeball lights" like you'd see over a fireplace. The guy who we are buying the home from didn't have all of his marbles. There are probably 7 of these. The 3 car garage is connected to the home.
When you say feeder tube, do you mean probably 1" pipe that would come out of the new panel?
What I would like to do is run the "feeder tube", attach the new panel, relay switches, outlets throughout the garage, lights, run the wires within the garage, but leave the major panel change and running those wires to the new box for the professional.
For the shop panel, would you recommend a 100 amp panel and what manufacturers do you prefer. I will probably have no more than 10- 8' ballasts for the lights.
I'm not sure how many 15/20 amp breakers I'll need, but I know for a fact I'll need at least 6-8 with room to grow to maybe 10 slots for just my 220 line equipment. I believe 3 pieces of my equipment require a dedicated 20 amp breaker for each. So if I'm at the new panel in the garage, what gauge wire should I run from the 15/20 amp breakers and what gauge for the 220 lines? Also, would you run 1/2" conduit or 3/4" around the shop?
To give you an idea about the machinery:
Powermatic table saw 3hp 220 volts, recommends 10 gauge wire, currently on a 30 amp dedicated breaker, 3/4 hp 1 ph
One dust collector- plugs into a regular 115 volt outlet, but requires a dedicated circult, 1.5 hp, dedicated 20 amp breaker
Wood Lathe- Plugs into a regular 115 volt outlet
Main dust collector- is 2hp motor 1 ph. 230 V only
Spindle Sander- Plugs into regular 115 outlet 110 V 1/2 hp 1ph
18" Band saw- plugs into regular outlet 1.5 hp 1 ph 115 V
Air filtration unit which mounts at the ceiling- Plugs into regular outlet 1/3 hp 115 V This will typically be running all the time.
Surface sander 1.75 hp 1 ph 115 V. It also says Motor "TEFC", what does that mean?
Bench top mortising Machine- Plugs into regular outlet 1/2 hp 1 ph 115V
At this point, I don't know what the motor for the spray booth will be, nor the explosion proof lights for it.
I will be adding a few drop down extension cords too. The 3 machines that will likely run at the same time are the 220 V dust collector, the 220 Table Saw and the 220 Ingersol Rand 60 Gal 5hp Compressor "which the compressor requires a dedicated 220 line also.
I looked in the manuals for each of these and this looks like the best knowledge I'm able to provide to you. I don't see anything about watts, so hopefully you can figure it out from what you see. and please type out how you figured this all out so I can see how it's done, vs just a final number or information.
Thanks for your help.
P.s. You said......
Regarding the dust collector. It would be easy to build a small control cabinet and run interlock wiring from the starter of the other equipments to the starter of the dust collector. A couple 120 v ice cube relays and an HOA (hand off auto) switch and you will be good to go.
What does 120 V Ice Cube Relay mean and hand off auto? With the HOA do you mean a disconnect switch at say the table saw? Yes, I'm a one person deal
