Please assure me I'm not going to burn my house down.

I recently bought some new mono class D amps to replace a stereo class D. I had a pair of identical diy power cords connected to the stereo amp and my preamp.

Well, with monos I was obviously going to use the identical power cords. So I needed a new PC for my pre, as the older diy version I had laying around just used thhn wire from Lowe’s and didn’t sound great. So, after some thought and research, I decided to make a PC out of cat 5 plenum cable. I kept it in its blue sleeve (containing 4 twisted pairs) and then I braided 3 lengths together for each conductor. I then took those three braids and braided them. What I have sounds incredible and I’m fairly confident that it is safe electrically.

Please reassure me. Or tell me I forgot about x, and that I should cease and desist. Or laugh at how cheap I am...

But really, I’m not going to start a fire here, am I? 8 conductors per length x 3 lengths for each conductor equals 24 strands of 24awg. Which equals 10awg for each conductor...

The only thing I can assure you is that I laffed my ### off at your post.
This ISNT advice on safety. Just perspective using a seemingly questionable PC.

I used one of these for several years without any problems. The construction possibly Iis even more dagerous appearing!

it made amp, source even TV perform noticeably better. The clear film eventually became torn in several areas, Scotch tape just made me feel uneasy about its safety.

Speaking with the company, I was told Pierre REMOVES the film in his setup!.

You may equate the gauge, but man, you are playing with fire, literally.

Let's say something does go wrong.... you could be held legally liable even if you do all the math right! :)

Much better to get a Connex shielded power cord and make your own.

Also, part of what you are not including in your calculations is the insulation temp rating. The insulation around Cat 5 signal wiring assumes nearly no current at all, while power cord insulation is rated to withstand the heat of the conductor at full current.


I actually thought about the insulation temp.. I purposely used plenum rated cable, which has Teflon insulation instead of PVC...

Do you think an insurance company would look more kindly upon diy cables of a different variety? I'd imagine they'd poo poo any diy cable.. But I'm not sure.
