Yes, tandem is also another term used here as well.

Since I did not use Google for my logging in here I guess people won’t be able to see my mugshot.

Side note, I hate this style of forum.  Emporia is reinventing the wheel here at it is awful.  There are plenty of readymade forum software out there that is way easier to use.  Oh well………

“you almost certainly don’t need to sensor both sides of these devices.   You may as well prove it to yourself now that you have done it but you’ll be able to recover 3 of the sensors for something else, just remember to set the remaining ones on the 2-pole circuits as “2x” in the app.”

It has been less than a week but here are my results so far:

A/C – 1 = 52.942   A/C – 2 = 52.592

Water Heater – 1 = 22.089   Water Heater – 2 = 21.934

Well Pump – 1 = 1.097   Well Pump – 2 = 1.088

So, yes, I could pull one CT and use the multiplier on the other but I think I will let it play out a bit longer.  I’ll be glad when the update to the app will allow combining but separate.  As a technical OCD person, I just want to know just-in-case.

Nice drawing.

I don’t think that would work.  Our dryer was used for the first time under Emporia yesterday.  Guessing 2 loads.  Dryer Leg 1 used 3.194 and Dryer Leg 2 used 2.748.  I’ve not looked at the electrical drawing of the dryer to see what is what….yet.  Nor have I checked the usage during an extended anti-wrinkle mode.

How did get your’s (or someone’s) Post Office mugshot to appear in your postings?  I looked but I guess I didn’t look enough.

What you have in the pic is what I call “twins”.  My Homeline panel by SquareD allows “twins”.  They actually call them “twins”.  This enables me to have more physical circuits than I have physical breaker slots by having two circuits using one beaker position.  It is no different than having 2 individual breakers feeding those 2 circuits.  If you are using the 2 mainline CTs then I would have a CT on each wire of each breaker.

Your small pic tells me you have 6 individual circuits that are being protected by 6 breakers that are taking up the physical space of 3 breakers.

You have such a tiny panel.  Mine has 40 positions and they can have twin breakers per slot so that can push the number of circuits to nearly 80.

[waterboyz]

I do understand what you are saying.  I’m still wrapping my head around the work-arounds.

[waterboyz]

The Gen 1 and Gen2  stand by themselves.  You can not add Gen1 totals and Gen2 totals.  Each Gen should show the same overall consumption.

Am I missing something?  As I raise my adult beverages to you.

My plan for 220v circuits is to monitor each leg with its’ own CT.  So, if my water heater generally has the same usage on both legs then I will remove one CT and use the multiplier on the other CT based on the usage.  It may not be exactly 1.00 but close enough for Government work.

As to dryers.  You will never be able to use just one CT on the circuit.  The heating coil uses 220v.  The motor and electronics use 110v.  When a dryer goes into “anti-wrinkle” mode, only the 110v is used.  Generally.

” I will be interested in ideas how to fix that.”

Me too.

I have a heat pump with a HUGE toaster as the backup heat.  My system has 2 60amp double pole breakers plus the 30amp double pole for the outside unit.

So…..

That is currently burning up 6 CTs.  I just got mine installed so I’m still learning it and collecting data.  Probably I will run the individual CTs for a few weeks to get a pattern.  Then I will use one CT for both poles of the breaker.

But aside from that the question is …. will that work and how long can they be?

============

I have another device that uses CTs.  That vendor said I could extend the wires to their CTs up to 36″.  That may be an option.

[waterboyz]

I think that most people install the main CTs for both Gen2s on the mains as a normal setup.  It is easier.

The Gen2-A will see the usage on the main and its’ CTs.  The Gen2-B will see the usage on the main and its’ CTs.  I’m guessing that both Gens will see the same overall usage.  You would, naturally, be concerned with the usage from the individual CTs.

[waterboyz]

I guess it depends on what it is powering.

I have a double pole 15A breaker because the cable from the breaker supplies the power for the dishwasher and the disposal.  Because of the electrical code, if the dishwasher trips the breaker the disposal is also tripped.  Safety.

The wires in the cable, in this situation, are black/red/white/bare.  The black feeds the dishwasher.  The red feeds the disposal.  Both units are 110v.

Just because you have a double pole does not automatically mean that you have a 220v circuit.

[waterboyz]

As JJ613 and Spiker 604 mentioned, I too have to figure which circuits to lump into the “all else” category.  I have 42 circuits so far in my one panel.

 

Since I have a newer home, each bedroom has one breaker for the lights and outlets.  Doesn’t do much good to monitor the usage since not a lot goes on in the bedroom.  I’m talking about electricity here.  Also, I have circuits that are dedicated like the microwave and dishwasher and garbage disposal.

What I probably will do is buy another 16 CT Gen 2.  I’ll monitor circuits of concern.  Other circuits I will monitor for some period of time to get a gist of its’ usage then move them into the “all else” category.

Some of my usage I can control and some are just part of living at home.  I’m not gonna stop using my microwave because I’ve reached some mythical limit for the month.

What it HAS told me, for the less than 7 days I’m on it, is that my heating is using about half of my monthly usage.  I’m on a heat pump with HUGE toaster heating elements as my backup heat.  I’ve told my Ecobee t’stat to never turn on my backup heat.  As soon as I can find a reliable calculator to convert electricity to propane I will use the knowledge from this monitor to figure in my Return On investment to buy a propane heat system.  I will have to do a test run of my toaster heat to get some usage numbers.
