hi Greyhound..
I was looking at the Neurio reviews on home depot and a similar problem was solved by a customer.
if I understand this right, he grouped all of the wires coming off the breakers from each phase and ran those wires through the probes.
Separate the wires into A and B legs and make sure the directions are the same on all the wires in each group. Seems like a work around, but if you have enough wire length to route the wires, then it might work.
You may do what he did and email Neurio customer support.

"I have to start out by telling you that the customer service is Excellent!
We are not a big electricity user. No kids, retired on a budget so every savings we can obtain is great. Knowing what each switch cost to turn on is eye opening.
I have a very small electrical box and the main power lines are covered and too big to get the CT's to fit.
I emailed customer service and they responded very quickly. I sent pictures of my small box and they advised me on how to install the system. The A phase and B phase wires are what I had to use as a work around. You need to understand how to read the breakers and what wires to group but it works great.
Thanks again to the customer service team!
