I'm curious what the two little blocks attached to the wires in the right side of the subpanel are. Are they current sensors? How are they used and where do you buy them?

Thanks,
Ray Maning

Ray, the black boxes are ct's.
Made by crmagnetcs.
I think they were around $20.00.
I use them to announce when the washer and dryer
cycles are complete.
Old way
Wife puts first load in washer, get involved with
other chores, and forgets about it.
Hours later she would remember, get one load done
per day.
With ct's washer done is announced, wife go's
opps i forgot,and inserts next load.
Many loads done per day.
I also count times dryer is run reminds us to clean outside lint filter.

I must admit, Ed has made my life easier with many of the daily hum-drum tasks.
The WAF is very HIGH!

Hey Ed (edr) - you've got a very understanding wife there (mdr)! My system also has a high (I think) waf but anytime I say anything that could be even remotely construed as complaining about how she does a chore, that chore becomes mine!

Crystal (our SpeakEasy) does help remind the whole family about closing the entrance-way door in cold weather and that was fairly easily accepted. Now if she could just help me with getting my clean shirts hung the way I like them (now my job). :rolleyes:

John, just put your name down as a beta tester for the new upcoming SECU-SH (shirt hanger) module.

Gotta agree with John and mdr, high WAF is the key to any system. Sounds like Ed has that one firmly behind him. Attaboy!

Thanks Guy's,
Didn't know my wife was posting.
She is very supportive.
I try to keep her involved in my HA adventures,
testing switches,watching lights,she helps with
autoaddressing alot.
Also does'nt get to upset about things like
2:00 am all lights on.
It's up to her to tell me what she would like the
house to do next.
Keeps me to busy to hang shirts.(he-he)
Thanks for all the help in the past and future.
Happy Automating
Ed

Enthusiastic wife...priceless!
Some things money can't buy...

Ed, now you know that not only does she appreciate the HA convenience, but she also tracks the web sites and forums you go to

Out of curiosity (for anyone who knows), would putting the CR Magnetic transformers inside the breaker box be against standard electric code, since there would be low voltage coming out of them (ie: mixing high and low voltage in the box).

Reason I ask is that I'm considering doing this as well and don't want to go to all the trouble this is going to be (and it would be considering where my breaker box is - running the wires back to my SECU16) if it would be against code. I eventually plan on building another house (about 2 yrs) and don't want to have to rip everything out before I sell it.

Ed - Also - what are the model numbers of the ones you're using? Are they going directly into the SECU16 as an analog input, or how do you have these wired? Just curious...

Brian makes a good point: it is probably against code to put anything inside the breaker panel. Of course your local inspector ("authority having jurisdiction") has the final say but it would be worth inquiring about it. A better alternative would be to take the wire for that circuit into a junction box (that could be located near the breaker panel if you want) and install the current sensor in the junction box instead. That is how I wired my own X10 signal coupling circuit.

Brian and Guy,
Not sure about code issue,but my guess would be
that it is not allowed.
Stuck them in there to see if they would work.
Then moved on to somthing else.
Total rewire of entire automation system is
scheduled for this winter.
The ct's are actually current switches, turn on
at about .35 aac.
They are connected directly across secu16
supervised input.
I heard of them either on this forum or
comp.home.automation.
Then can be purchased at.
Crmagnetics.com
Current switch.
Part# CR9321NPN.
They are rated for 100 aac continuous, 500 aac for
1 sec.

Follow up,
Checked with two electrical contractors here at
work.
Their opinion's were it's ok as long as the sensor
wires are ran through a proper connector where
they enter the panel and protected by some sort of
insulating tubing.
They will get back to me when they can point it
out to me in the nec book.
Will let you know.

Ed, Thanks VERY much for the information.

Also its good to know that there are ways where installing some of these things in the box might not violate code.

That being said, I have an HCA-02 and whole house surge suppressor actually installed inside my breaker box (velcroed to the side far away from wires with any current) that probably violates code.

However, this was really the only way I could install it, as I wasn't about to rip out sheetrock in the basement bedroom (where, for some stupid reason, the breaker box is located).

Brian,
Your welcome.
I have just found another gadet that you might be
interested in.
It's an air filter monitor from brookstone.com
about $40.00.
It's a standalone anemometer.
(Must airflow sensors I've seen up to now use
some sort of heating element, don't want heating
element in ductwork.)
You program manufacturers filter replacement
interval, and when it see a 20% reduction in
airflow it flashes, and beeps it think.
Put it in service yesterday,screws to filter grill.
Will see how it works.
Eventualy will hack it for connection to secu16.
And mount in duct.
Right now i just look at vacuum gauge whenever
i remember.
Both wife and i are very sensitive to dust.
If i can make this work, the waf will go off
scale.
Happy Automating
Ed

Ed,
How far are the CR9321 current switches from your SECU16? I'll have about 30 feet between mine and am wondering if that will result in too much of a voltage drop.

According to the CR9321 data sheet, the NPN transistor can sink 120mA at 5V. I'm guessing that an SECU16 input set to supervised mode must apply a voltage to the CR9321 leads. Anyone know what the SECU16 voltage is and at what voltage threshold the SECU16I input detects a closed circuit?

Steve

In supervised mode, the SECU16 is pulling up to +5 volts through a internal 1k resistor. The external 1k resistor that you (should have) installed across the input, in parallel with the CR9321 creates a voltage divider. With no AC current draw detected by the CR9321, the voltage across the supervised input should be close to 2.5 volts. If a sufficient current draw is detected to turn on the NPN transistor, the input should drop to less then 0.5 volts (should be about 0.2 volts).

If your parameters 2 and 3 are set to the default 64 and 192 values, the status should go from Off to On when a current draw is detected.

Thanks again Guy! If my calculations are correct the current sensor should be drawing less than 5mA, so I shouldn't have any problem locating it a good distance from the SECU16.

Have you ever thought about going on Jeopardy? You'd do well with topics like Ladder Logic for $100 or Ocelots and Leopards for $500.

[/qb][/QUOTE]There should be no issues with distance, this being a static, DC signal of very low impedance.
