Seeking cable management ideas....

Without an iron core of some sort I doubt if there's much risk. However wiring regulations require that mains carrying cables should be either 50mm away from low voltage ones or that there should be 'mechanical separation' between mains and low voltage wiring. (That's the basics anyway).

I hadn't considered electrical codes 8-) I suspect that very few computer setups in homes observe a 50 mm separation rule, at least here in the US. Still a picky inspector might take issue.

Thanks!

I'm quoting UK codes of course. I *think* mechanical separation would be satisfied by an extra layer of sleeving over the actual wires carrying the mains voltage. It is now a requirement in the UK (and EU I believe) that all mains leads are sheathed, you can't use the 'figure of eight' twin flex that used to be quite common.

Electrical codes only apply to the fixed wiring of the building, not to power cords, trailing 4-way extension leads, USB, HDMI and ethernet cables.

But power cords are required to be sheathed aren't they?

True enough other regulations apply to plugs, cables, extension blocks etc. restricting what can be sold rather than how it is used.

And like the pirate code, they are more guidelines

More than that - watch what happens to the fire insurance claim when they find the place wasn't wired to code.

Agreed.

Though the Fire Martial sure can have a lot to say about it and building occupation being legal or not.

If you don't want lots of little power cords, yes.

The correct term is double insulated.

Different way of achieving the same result. I looked it up and tried it and yes it works but it just seems a more involved process that doesn't commit to muscle memory in quite the same way but that is probably more habit than anything else, indeed playing with these things I found it hard _not_ to automatically apply the BBC method.

No.

You would need to check the voltage between the two ends of a wire, which is near zero, and *that* voltage would be transformed to the secondary (low-voltage) side, not the voltage between the two wires.

Furthermore, the fields from the two conductors with opposite current direction nearly cancel out, which reduces the effect even more.
