Description:
It appears from some playing around that nothing in RFTools that outputs FU/RF will push to Fluxed wires.
Its too hard to tell whos side this is on so I'm posting it to both.

Recreate:

1.setup RFtools power provider
2.connect to provider using fluxed wire of any kind.
3.connect a power reciever.
4.no power will even enter the wire network

Versions:
Minecraft: 1.11.2
Forge: 13.20.0.2252
Fluxed Redstone: 2.6.0.54
RFTools: 2-0.011

Edit: It occurs to me I didn't clarify "Will still output to RFTools" Using a forestry engine as a power provider successfully pushed energy to the crafter in the linked picture.

As rftools can successfully push to other RF/FE/FU consumers I would think this is more like a bug in Fluxed Redstone but I like to hear what they say about it

As I thought. I'll keep you posted.

Thank you for taking the time to create this issue, as we're no longer supporting versions below 1.12, I'm going to go ahead and close it but if this bug seems to continue over to newer versions, please do report it again so we can investigate the issue further.
