It does
If the value is negative, just turn the clamp around
December 7, 2022 at 12:41 am in reply to: Combine 2 Circuit into a single reading? #9169 Report AbusecharettepaMemberFollow my diagram above and you can use one set of clamps on your unbalanced 240 dryer. I have been running this way for about a year now.

September 11, 2021 at 2:51 am in reply to: Combine 2 Circuit into a single reading? #7962 Report AbusecharettepaMemberI am running the emporia V2
It actually supports up to 3 phases
I am running both legs of the 240v dryer circuit in one clamp. I am not using a multiplier.
It’s not just double.
I started out with 3 clamps for the dryer. One on each leg plus one over both in opposite directions. I ran it this way for several days. The 2 separate clamps always added up to the single one despite the 2 separate ones having 300w difference.
I have spoken to emporia support.
They confirmed that this setup is correct as long as the wires are long enough to achieve it and the clamp is large enough for both wires

September 11, 2021 at 1:52 am in reply to: Combine 2 Circuit into a single reading? #7960 Report AbusecharettepaMemberin my case I combined in 2 cases
1- the AC which is balanced
2- the Dryer which is not balanced
the dryer always had 300w more on one of the clamps
which i’m certain is the motor turning the drum at 120v
while the heater is 240v
the 1 clamp that has both loads of the 24ov circuit for the dryer
it measured an equal amount to the other 2 added up on each separately until a few days ago when I removed the individual ones
example p1 was 2800w p2 was 2500w and the combined one was 5300w
when the heater would periodically stop and only the motor was going the single one and p1 both would register 300w with p2 at 0w
then heater would come on again and it would return to p1 was 2800w p2 was 2500w and the combined one was 5300w
as a whole, yes it may be off by a few % but thats the same individually
this should be far more accurate than picking one and multiplying by 2 as its measuring both of them

I used 3 clamps total 2 separate and one with both wires. I ran this way for 3 days. All numbers added up. The 2 separate values address exactly to the combined one.
September 10, 2021 at 6:38 pm in reply to: Combine 2 Circuit into a single reading? #7949 Report AbusecharettepaMemberthis can be done, on unbalanced loads with neutral
but…..
you need some slack in at least one of the 2 load wires
the second phase must be looped and inserted into the clamp in reverse as the current is going in the other direction
the only limitations are
if too thick and you cant fit both into 1 clamp
or
if the wire is too short as you cant loop it to reverse it
if its too short
1 alternative is to disconnect the 2 load wires from the double breaker
cross the wires
going from this
1=============1
=
2=============2to this
1====\ /====2
= =
2====/ \====1effectively creating an X pattern and putting the load in both directions
place the clamp in the center of the X pattern and it will pick up the full load on both wires
if it reads negative, just reverse it
this has worked for me
