OT for a sec: US wiring sources of info

[Jules Richardson]

One for the US members... any idea of a good usenet resource for 
questions relating to US wiring / electrics? (I'm thinking an equivalent 
to uk.d-i-y)

We've got a cable decoder box here that trips out the house breakers 
when plugged into certain outlets - irrespective of whether it's via a 
surge protector (probably not surprising there) or of what other loads 
might be sharing the same wiring to that outlet.

It works fine in other outlets though, which seems like a strange 
problem - but I have no idea how US houses are wired (and the wiring in 
this place is ancient anyway!)

Be nice to get it sorted out as the cable box currently requires a cable 
trailing across the lounge from an outlet in another room!

cheers
