Can I install using both sides of a double pole 15 amp? Instead of two single

[Ann]

Does the wiring effect data? Or is it just power?

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.

If the double pole beaker occupies a single slot in the box, it is sharing the same phase to both circuits.  In this case, both wires can go through the sensor in the same direction and you will have both as a single channel in the app.  All of my 15’s are like this:

If it takes up 2 slots, like US 220V breakers, then one of the circuit wires would have to run through the CT in the opposite direction as to not cancel out the other phase.

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.

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.

Waterboyz-  Yes, the builder didn’t cut corners on over-filling my box!  Unfortunately, when I went to install the Vue I discovered that all the Challanger breakers were condemned about 20 yrs ago, so I replaced them all.   Around here at least the twins are more commonly called “tandem” single poles. Many people confuse the terminology which is why I posted.

 

As far as my profile pic, I didn’t do anything to display it, but it’s my Google account picture and was likely automatically loaded when I signed into the forum with that account.

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 can put multiple wires in a sensor if they are on the same phase.   It doesn’t matter if they are on a double pole breaker or even if they are adjacent.

Usually, double pole breakers are not on the same phase, whether they are used as 220V or for a common trip and common neutral as in your case, they do not tend to be on the same phase, although it is possible.

The Vue is not very useful with the Disposal BTW.   It doesn’t capture the high peaks of power draw and doesn’t retain the granular usage (a few seconds at a time) for long enough to be useful.   The long-term energy usage of the Disposal is so negligible it doesn’t appear on most graphs and reports.  If, as is typical, you load the dishwasher, turn it on, then run the disposal for a few seconds it will be invisible in your Vue data.

A true double breaker will use both phases.  A twin/tandem breaker uses only one phase.
