Hi Aaron,
I put the panel on the post for the kitchen after discussion with Zedd, 
Miloh, and Jim and a few others. Its in an excellent position from the 
standpoint of being out of the way of cooks and eaters, and the many 
pathways out of it to other key locations, but the location is part of a 
plan, if the plan is not communicated to those that carry it forward it 
is unlikely to be simple or as useful as if the plan is completed. I 
don't know what other people's schedule is for finishing the build out, 
but when that time comes I will try to clear some of my time and finish 
connecting up the panel or at the least laying out the design on whoever 
will take it forward. If build meetings are still occurring on Friday 
nights, I'll try to make it, especially if work on kitchen or on a media 
area resume.

To answer the question about sizing: the 100 amps 3 phase was because 
the kitchen crew planned a 220 50 amp oven and stovetop, a 220 30 amp 
water heater, a 220 30amp clothes dryer, a washer, additional kitchen 
appliances, plus this was the only new panel delivered to that entire 
quadrant of the space so who knows what might come: (since the panel was 
installed requests for a fan/blower, and dark room have come forward.)

Unless I've forgotten, (?) the panel in the shop is three phase and was 
sized for two reasons: three phase 50 is plenty for the list of 
equipment that Jim thought likely to eventually be in place: small 
lathe, cutters, printers, drill press, perhaps a band saw. Nothing that 
burns like a welder or paint oven, nor any other really large electrical 
draw (motors not heaters in contrast to the kitchen/laundry/bathroom.) 
Secondly, we had extra #6 wire so it was cheap and on hand to put in the 

Its exciting to see the space getting used, I showed up Monday for 
electronics class and got way laid by a notebook vs water crisis so 
missed the chance to build my own TV be Gone.  

I'm looking forward to having a great kitchen and a decent media space 
after the next wave of building.
