Typical wood shop outlet

[Charged]

I run into a lot of wood shops and other labs on educational buildings and other commercial buildings. The instructors are always excited to get a new space, so I always spend a little extra time trying to lay out the space power and lighting best I can for them. I always try to future proof things if possible. Ive used bus duct in the past for larger shops.

I provide power based on all the current equipment. If they bought something new, Is there a typical nema configuration that newer shop equipment goes with for "220V" equipment.

Any recommendations of setting them up for the future in case they upgrade.

i.e. Would it be better to sprinkle some 30A fusible disconnects or some outlets (if there is a typical configurations with manufacturers). Maybe just a box with (4)#10s+G. That should cover them on all 20A and 30A configurations.

I'm sure more details are needed, these are shops that are not doing bulk manufacturing or production, band saws, drill presses etc.

I have several wood shops in schools. The last one was all 3 #10's, neutral and ground to each and every box. Every outlet is then capable of 20 or 30 amps, single or three phase. In schools, the machines tend to change a lot and all I have to do is change the plug/breaker. The additional benefit to this is when they order, some configurations are less expensive or have a better availability. Being able to adapt is a huge benefit.
It's an extra cost up front but the only things I've had to pipe now are new pieces of equipment in a new location which is rare.

Nice ! Thanks for the feedback. Glad the #10 idea isn’t off base I came up with that while writing the post and thought it was a good way to go. I’ll look at doing all the boxes in the heavy equipment areas of the shop like that up front not just sprinkle some.
Thanks !

I was in another school shop today where they are relocating most of the equipment to the new building we’re designing. The shop teacher actually requested something similar to what you proposed above. Everything seemed fine then I started looking closer at the equipment….. They are utilizing a 208v 3 phase 200a bus duct to feed 80% of the equipment. All the equipment has had the plug switched out to a 3 phase Nema configuration. The bus duct has a 3 phase so drop with matching twistlock receptacle. Some of the equipment is 208v single phase and 120v ,they just don’t have all the wires connected going to the 3 phase plug obviously.

is this ok ? It seems like it should be wrong but I can’t come up wi try anything but I’m curious how to handle it at the panel if I don’t do a new bus duct. Just provide 3 pole breakers for everything?

the receptacle being used is a p&s 7413ss on everything.

I think the fusible disconnects would work the best, the equipment can be easily locked out, fuses are much easier to change out, as where if in a breaker panel, it would require the panel to be shut down, regardless if bolt or plug in. 15, 20 and 30 amp fuses could be used depending on the equipment requirements.
