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...
