The Philips Pronto let’s you name keys and edit the screen layout but I’m pretty sure they are discontinued now. I have an 18 year old one that, amazingly, is still working.

American Wire Gauge (AWG) to mm² conversion chart.

2.5mm² copper cable has a resistance of 7.41mΩ/m, so the loop resistance for a 8m cable should be around 0.118Ω.

That measurement seems quite high. I’d expect it to be around half that.

I never would have guessed AC current was directional!

He was asked to provide this on the Wam thread and refused.

My audio system is there to serve me, I’m not a slave to my audio system.

In other words it has to be ready when I need it. No faffing or fiddling needed to put some music on, no waiting for...

I wouldn’t touch half of these audiophile fuses with a barge pole.

Very good points/questions, Martin. I’m with you on this subject, a non-problem looking for a solution. I know I may be unpopular for this view, but how many people who have this problems with the...

There was a report conducted a few years ago on these...

I did ask in the grounding box thread about how potential problems manifest themselves audibly in our systems but didn’t get a solid answer. Why spend time, effort and money trying to fix a...

Are you sure the part I have highlighted is correct? For optimum safety it should be a double pole RCD on the secondary supply of the BMU.

I seem to remember reading somewhere that high frequency currents, assuming that these are the ones we are trying to minimise, follow the lowest inductive(?) impedance path.
I’m a little hazy on...

Hi Alan, thanks for the reply.

So are we back to thinking that these grounding boxes and cables are acting as an aerial/antenna? But somehow instead of feeding the “signal” into the Hifi there is...

Hi Marco, your electrician will be measuring the earth fault loop impedance, on a TT earthing system (where safety earth is provided by a ground rod) the better the soil conductivity the lower the...

I think your confusing Earth Fault Loop Impedance with mains impedance here.

I am not missing the point, I pointed out some inaccuracies in the CAD link. Some ground boxes are designed to connect to mains earth, the RTZ is not one of these designs.

I cannot work out how...

Both sections in the quotation marks.

“For safety reasons, any electrical device in a conductive (metal) casing must legally have an earth connection. Most audio components have metal housings that must be earthed - the exact same earth...

I have just had a quick read and this didn’t explain much. In fact there are some technically inaccurate statements in it, I’ll let them slide as it does say it has been written for people with...

A second hand piece of equipment I bought had them fitted, took them out after a month, made no difference so I flogged them on a certain internat auction site.

Well, looks like we have slightly more to go on now. So it doesn’t follow the same path as Entreq’s products which appear to be filled with a mineral substance. You mention bus bars, I am assuming...

My point was that is, for example an amplifier, that has 0V referenced to mains earth (via the amplifiers classic/case) then it would be an earth path.

Good post alphaGT.

It was mentioned earlier in the thread that some equipment may have mains Earth and 0V connected together, in which case I cannot see how a grounding box could provide a lower...
