Network Cable Routing Advice Please

Hi

Just a simple question I need help with please. I'm doing a network cable
run in a large house and I know they should not be laid in parrallel near
power cables but how near can I put them.

The reason I'm asking is the electricians have already been in and raggled
walls, laid cables under floors etc and it would be nice if I could use
their route as it would save me lifting floorboards etc. How near to an
electrical cable can I go?

Thanks in advance

As far as the concern with noise, just do the best you can to put some
space between them, especially on long runs; they're differential, so
can handle some common mode noise. More importantly, follow applicable
electrical codes, which might specify minimum distances between power
cables and low-voltage wiring (and, e.g., not allow them in the same
conduit). Also, be aware of restrictions on use of plenums.

Another possibility for you would be go with either phoneline
networking, HomePNI, or powerline networking, HomePlug. Both of those
use the existing cabling in your house to allow you to route data to
different parts of your house without requiring you to route ethernet
through them too. However, Ethernet would be much cheaper than either of
those two.
