i do think since CCL will be pulling from a different panel that we
should have enough amps from 4x20 amp breaker positions. the balcony is
set to get its own 2 runs (with one 20A plug on each run) for the server
farm and any amplifiers set to run there, the 3d printing area and
museum have a breaker run, and the tool area will have its own breaker.
the only complication in my mind is the back set of outlets sharing a
breaker with the tools and someone bearing down with a chop saw just
before someone hits save on the new greatest cryptographic algorithm on
their laptop. that's what pushes it to 5 positions in my mind if it were
easy to get that 5th run energized.
we do intend to run a separate 230V service later for the heavy stuff
over 2 outlets, so maybe we could identify a spot for a breaker to be
installed under stage 2.
cheers

Fine by me. Just my opinion that loads add up. Indeed
we use more things with small loads than ever before... I have worked on houses that get
by on two fifteen amp circuits in San Francisco and I have had problems with two hundred
amps 220 volts not being enough...

few things that use more than 100 watts, and the number is diminishing constantly. a
laptop takes no more than 100 watts max, typically around 50. 60 watt lightbulbs are
occasionally used, but more often we use 24 watt CFLs, when we're not simply using the
overhead lights. Desktop computers with their monitors take a total of less than 200. 3d
printers take between 50 and 100 watts depending on how much heating is needed. A heat gun
can take 1500 watts, but a 20-amp breaker can supply over 2400 watts. Without a more
detailed list of what people expect to plug in, we can't be sure one way or another
whether there will be conflicts requiring something to be plugged into a different outlet.
But my experience tells me that what we have sketched out so far is more than enough. and
we know for a fact that increasing service will correspondingly increase costs and time to
completion, and complexity if we run
out of circuit breakers overestimating our
needs. Worst case is that you have to plug the second autoclave into a different outlet
than the first one. -jake On Sat, 6 Sep 2014, Dave Pedroli wrote: Hi all, Going over your
emails and PDFs it looks good however putting more than a couple outlets on a breaker will
end up being problematic. Yes refrigerators are smaller loads but there will be a time
when someone opens all one after the other and they try to start all at once blowing a
breaker and defrosting... Autoclaves typically need their own circuit etc ... 13 outlets
with 4 breakers is pushing it. If the majority of use was to be laptops and soldering
irons ok but the minute a heat gun is plugged in poof, you blow a breaker. With
electricity and parachutes it's best to start out right rather than build up to it.
I'll go over the PDFs on my iPad later and let you know what I think. The layout looks
fine, the number of outlets looks good it's just the the number of circuits
(breakets)
that needs improving. Dave Somewhere on the bonneville salt flats Sent from the

the electrical panel in the balcony only supplies one or two things (not including the
robot, which is a temporary connection) I think we should look into simply moving that
breaker box down ten feet so it faces the server room, and be done with it. On Fri, 5 Sep

proposal. Your interpretation of the plans is correct.{ Main -> above stage panel ->
balcony panel } is how the proposed plan is drawn. There is enough room in the balcony
panel (which is the one located in the small room that shares a wall with the server loft
of sudoroom) to accomplish phase 1 of the proposal. The proposal is based on instruction
received to minimize cost. Ideally, there would be a main panel breaker that supplies a
sub panel for all of sudo's needs (phase 1 and
phase 2). I can't accurately guess at a cost number for this type of installation.
Figure a 100amp sub with hundreds of feet of 2awg plus breaker box plus breakers plus
conduit plus hardware. All depending on if the main service can even handle the additional
power demands (hiring an electrician to run the calcs). Ballpark $3-5k maybe- but its
really a shot in the dark? My experience with this type of thing is there is always a
better way to do it, if you go the money. A middle road is to plan on having the future
sudo-sub panel placed near the balcony panel. Build in an extra 5ft or so of wire for the
future transition into the new sudo-sub panel. All that would be needed is to remove the
breakers from the old box re-run wire from J-box 1 to the new sudo-sub, as well as
re-routing the 240V lines from the above stage panel to the sudo-sub (and of course
preform all the main -> suod-sub work). as far as existing vs proposed. only the sub
panels mentioned above exist currently- I'll
make a note to call out the existing stuff in the drawings. Thanks, Whit On Fri, Sep 5,

the first time I have looked at these plans and I have some questions and thoughts. Dave
said he won't be able to respond to this email until a couple of days as he is out in
the boonies somewhere. So I am writing in to expedite some issues that I think he will
likely bring up in the days ahead. Whit, thanks for drawing up these plans! For someone
who is not intimately familiar with our electrical layout the plans might need a more
clear description of existing electrical vs. proposed new electrical, however. In multiple
conversations with Dave (and one on-site visit) he has mentioned repeatedly that we will
want to shoot for putting in another sub panel for the sudoroom off of the main panel as
the end-game; rather than daisy-chaining off of an existing panel (the balcony) as what
seems to be proposed here. If we
can't immediately put in a sub panel into the room, due to cost, we should at-least be
planning for conduit and wiring paths, etc that allows for a sudoroom sub-panel in the
future. Thoughts? -Cere On Fri, Sep 5, 2014 at 10:23 AM, <hol(a)gaskill.com> wrote:
