Electric and audio wires

Posted by: antmast on 01 January 2013

HAPPY NEW YEAR!

 

A couple of months ago I got some excellent advice here about the using separate switches from separate fusebox fuses for audio equipment  and internet equipment to avoid interference. Stuff like the amplifier, tv, UnitServe SSD could receive interference from internet equipment like the ReadyNases (external harddrive servers) , internet switches and cable boxes. I was thinking about spending some tax refund money to get something done with the electric house wires and the fuses to better isolated one from another and would it be worth it. Should I have to separate the units physically if they are plugged into separate sockets which are controlled by different fuses.  I like the way they look all lit up together on the tv cabinet. Kinda like one happy family.

 

Thanks

Hi, happy new yeat, I think ithere is an argument to seperate ring or spur circuits for audio and other devices... But I would be more concerned about placing your Naim audio very close to your TV. What is the TV technology? Certainly plasma TVs radiate quite a large field strength ( through the air) and could affect the audio components in a more negative way that a small amount of noise on the mains from a SMPS elsewhere in the house. BTW it goes  without saying Ethernet over mains are a complete no no for cleanish mains... Even from a neighbough which could be a tricky conversation...

My TV is LCD, Samsung un55c8000. My audio gear is on the shelve below. Is this bad? How do I know what has spur or ring circuits? Thanks

Hi, I guess your LCD TV should be fine then assuming its SMPS has no missing parts/correctly designed .. But I am sure a brand like Samsung you will be fine.

As for the spur and ring main, I thought regular spurs were limited to a 13Amp socket. Ie a 13amp fused combo or a single socket. Ring mains can have dual 13 Amp sockets. You can switch your power off, and unfasten the socket covers and check to see if you have two neutrals, lives and earths entering the socket or just a single set. Clearly a single set will be a spur. An electrician can confirm for you.

You will not be able to confirm how your circuit is arranged just by looking at the socket wiring.

 

However, if there are two sets of cables behind then it is more than likely part of a ring circuit.

 

However, it could be a radial.

 

I would contact a local registered electrician who im sure would be happy to help.
