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
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.
