It does

If the value is negative, just turn the clamp around

Follow 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.

I 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

in 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

Before switching to double clamp I compared the values. 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.

[charettepa]

this 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=============2

to this

1====\     /====2
=           =
2====/     \====1

 

 

effectively 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
