EMI from residental furnace
<!=question>I'm a general contractor and I have a homeowner question. In the attic we installed a new furnace and new CAT-5E network wire. Do we have to worry about the blower motor in the furnace interfering with the network wire?|

You should be fine if you can just stay 2~3 feet away from the motor itself and the cables that power the motor. The interference will occur, but the electromagnetic field strength will me much lower than the CAT5/CAT6 3 V/m limit.
Anyway, it's much less dangerous for the network than for the phone lines since the frequency of the EMI signal is so much different from the signal frequency used by networking equipment.
