RE: Cabling (Cat5 and Power) in trunking

["Paul Gale" <groups@xxxxxxxxxxxxxxxx>]

Sorry Mark - should have made myself a bit clearer - I already have about
4=
Km of unscreened Cat5 in my house and it does get close to lighting power
i=
n a number of places without problems.

I'm wondering if anyone has heard of any problems running it in relatively
=
close proximity to power for LONG runs in trunking in an office
environment=
?

Ta,

Paul.
