Teflon wire casing?

[gobble]

I am looking for electrical wire casing used for concealment on the wall - but I dont wont PVC which will possibly melt after a 600volt surge. I think teflon is more suited for my application but I cant find any wire casing made of teflon. Any pointers?

I doubt it will be available .... that to at a reasonable cost.

Maybe you can consider a metal conduit ? Wont melt.

Worst case if the wire overheats and the bare conductor is exposed and touches the metal conduit internally, it will safely ground it... blowing a fuse.

As I understand it, which is not a lot....

It is not the voltage that is going to melt your wires, it is the current drawn. A piece of equipment will draw more current to do the same work with less voltage. Thus, could one not say that low voltage is more likely to cause fires? This is what caused my main, incoming 3-phase supply line to catch fire.

So far as wiring in the wall is concerned, is it not enough to look for reliable, named brands, that claim to be fire-retardant? Are there not ISI standards? And can they not be trusted?

Another thing to help prevent house cable fires is not stuffing conduits with them. Leave plenty of space.

I want it to drill holes and directly mount electronics like capacitors and chokes not for concealing wires. Hence the requirement for something that will not breakdown during a surge. I don't want the trouble of making a custom PCB rather quickly mount and solder with point to point wiring.

Oh sorry! I jumped to the conclusion wires concealed in walls!

:lol: :lol:

Yeah for that reason I can't use metallic box as anything mounted on it will short.

I just realized, I would add a fast blow fuse anyways for safety. So an inline fuse holder in place, and it will blow before the current surge has time to breakdown the pvc.

So I guess using PVC is safe in that case (pun!)? Heck all the pvc insulated wiring before the circuit has to burn before it reaches my circuit.

But in a more generic case, like for example a DIY tube amp built with point to point wiring and a steady 400+ volts it won't be a good idea.

Single core Silver coated Teflon wires are easily available in 22SWG and 20SWG at LR Mumbai. I have used them for my internal wiring for my speakers.

I am looking for casing not wiring

Ok, now I am looking for a one to many terminal block. i.e I want to distribute the mains wire to many outlets using a terminal block. But the standard ones I see only allow a one to one connection .

What do you guys recommend?

Edit: Is something like this available locally? I need 1:2 and 1:4 distribution.

Terminal Block - power distribution 15A

I need something that will also facilitate star grounding.

I think it is called a bus bar.

If you look inside your mains distribution box, you will probably find them connecting many->one for the neutral and earth lines.

You could make one out your pictured block by connecting all of one side together with loops .

(Actually, I nearly did that recently)

I did that for a grounded grid clone preamp build once. This time I want to do everything the proper way.

I think I now know what to ask for at S.P road. Thanks

I did say "I think..."

Don't blame me if they laugh at you and ask you to make up your mind if you want a bus or a bar! :lol:

Scroll down the Google Images search, and you can find the concepts getting confused

 

[gobble]

No yhat pdf for the power distribution thingie also mentioned a bus bar topology. So I think you were mostly right.

Anybody knows if I can get matrix boards without copper? Just for mounting and handwiring?

Does this board have copper traces? Matrix Board
