Standard for the distance between Elec. & Data connections / cables

AI Thread Summary
There are no universally accepted standards for the distance between electrical and data cables in electrical equipment, leading to confusion among professionals. The Canadian Electrical Code recommends maintaining a distance of at least one foot between data cables and standard power cables when running parallel for extended lengths, with a preference for crossing at 90 degrees. Noise immunity can be enhanced by using twisted pairs and foil shielding in data cables. It's essential to consult local power and telecommunications authorities, as regulations may vary by country. Proper separation of these cables is crucial for minimizing interference and ensuring equipment reliability.

Hi Guys,

I am trying to find out if there are any standards / regulations (world wide) for the distance between Electrical and Data cables and or connectors in electrical equipment.

There is some info on medical equip. and cabling in buildings but nothing on the actual equipment. Its logical to try and place them far a apart as possible, but I can't find any info on it!

thanks:smile:

I always made sure that data cables and power carrying cables were in separate conduits.
 
If I recall correctly, the recommendation in the abridged CEC (Canadian Electrical Code) is to keep datacomm (regular Cat-5, Cat-3 telecom, etc.) at least a foot away from standard 15/20A cables when they must run in parallel for more than 3 or 4 feet, and preferentially that they only cross at 90 degrees There is some noise immunity offered by having twisted pairs (at least for Cat-5e) and foil shielding (some of the more expensive Cat-5e, Cat-6).

EDIT: Parallel distance added

Dunno what country you are in, but the first place to check would be with your local power and telecommunications authorities. I am sure it varies from country to country. You need to find out what the rules are in YOUR country :)

cheers

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
