There are rules for residential and commercial installations that have actual legal consequences attached to violating them (and recorded in the law as local Codes). The fact is, the amount of interference that an electrical wire or other source emits will vary depending on what you have plugged into it, and when you are using the plugged in device. So, in their particular situation at the time they stated this anecdotal evidence, this has become fact and they repeat it as such.
In their case it likely did not or it went unnoticed at first, because the electrical wire was not being pushed to its amperage limit. The top two things to consider when faced with this situation are:īe careful of anecdotal evidence or advice! Anecdotal evidence from some (well meaning) individuals say running Ethernet cables or coaxial cable in parallel to electrical at closer distances causes no harm.
