Some Recent Work

Mark Twenhafel

New 600A Service


Parallel Lateral Conductors


POCO/HO Interface? Maybe some of you pros can explain this a little...


Makeup in auxiliary gutter


RNC for Service Entrance Conductors


Graphic Eye controllers will go in these boxes.


More Graphic-Eye Lighting Control Boxes--blue is 4-conductor low-voltage that hits all the remote control pads. Each set of individually-controlled cans gets its own homerun. The extra NM is just in case these boxes move.


Oh, BTW--we have a hole in our schedule. Anyone reading this in Tucson, AZ...well, we're available for (properly permitted) work. Hope this doesn't violate TOS.

Peace out.

In the top photo, on the right - next to the very nice SS box is the meter pan. Between the meter pan and the SS box is 3/4" (maybe 1") pipe.

The meter will use small wires...probably #12's maybe 10's.

But where do they go in the SS box?

In the bottom picture, there is a gap between the upper and lower sets of lugs. Across those will be fuses and current transformers (CTs).

Here is the basic concept behind a CT:

In your example, the arrangement would be like something like this:


Substituting the 3Ø motor for a 1Ø service from the poco....and the ampmeter shown above being your actual meter in the pan.

The white square boxes in the picture would be wirenuts for your transition from the leads on the CTs to the meter pan connections.

Are you allowed to mix low voltage line voltage like that?

If the insulation temperature and voltage ratings are the same.

What mix are you talking about?

I think he's talking about the Lutron system. I was going to ask about that. Do the Grafik Eyes have a remote panel. Usually with MUX link type cabling, all the loads go directly to panel, not the switch. Or is this the interlink between GE's?

Service looks nice by the way. 600 Amp? Must be a giant.

Celtic

I was still at the service



Lutron's "All-in-one-cable"...it's rated for it

Stainless Steel. Though could be polished aluminum too.

Thanks, Celtic. Makes sense now. :-)

yea, kept getting lost in it the first few days. Too big for me. :-)

I was wondering about this, too, but never asked. Thanks, Celtic, for the clarification below.

I didn't really get lined out on the Lutron--I'm still the new guy. :-) The way I understand it, in the picture with the three masonry boxes and the one Bakelite single-gang, the two upper masonry boxes get the actual microprocessors/controllers, while the single-gang gets the touchpad that the HO uses to switch and control the lighting. There are about seven touchpads scattered throughout the house and the blue Lutron cable just hits every one in one big circuit. At least, that's my understanding.

You kinda' lost me here, Goose. MUX is multiplexor, right? Honestly, I'm not sure exactly where the controllers go--my understanding is they go in the masonry boxes. These are in the Great Room, and there are some more similarly-wired masonry boxes in the adjoining kitchen/family-room. The foreman was talking about another house he did with computer-controlled lights. I think it was *not* Grafik Eye. In that house every set of cans has a 12/2 homerun to the panelboard and (I think) there was also a 12/2 "homerun" to the low-voltage, light-controller panel. Something like that. Sounds like you know about it. :-) There are also about 8 boxes for low-voltage transformers in a pantry and several more in a little closet. I'll have read about Grafik Eye so I can ask intelligent questions.

yea, stainless. Not quite sure how she slipped that one past. :-) One thing for you guys to keep in mind--with all the overhead and delays from all the designers involved--lighting designer, interior designer and landscape designer, and then they always had something that they wanted to wait to ask the HO about--I don't think we actually made a lot of profit on this job. The foreman spent a *lot* of time planning and meeting--that's not how we usually work.

Thats good to know, I'm getting ready to bid a 10,000 sqft house with 800 amp service. So I should price my labor like a commercial job.

220/221

High end residential customers are WAY more diifficult than commercial customers. Price it high enough to deal with all the added BS.

One example is switch box placement. In commercial work you place them whever is close and makes sense. In high end residential, the designers don't like to have switches/thermostats where their artwork is going. They also add a lot of wall treatments that will compromise the box placement. Pay very close attention to the elevations (if they even have them drawn).

Watch the MAC's (Moves/adds/changes)....have a clear written policy on:
- who is authorized to initiate these MACS
- how payment will be calculated (mobilization/demobilization, etc)
- when payment on MACs is due
-etc

MACs will KILL you on this job...documenting the changes and getting paid for them is the name of the game.

Holy smokes!

800 amps for a 10,000 square foot house?

The largest house I can remember wiring was almost 7k and even that was only 300!

Good luck.

OFF Topic:
by the way, where is Burlington, NC?
I have parents who live in Calabash.
