Quit using that piece of crap installation. If you cannot wire it yourself, hire someone that isn’t willing to cause a fire.
I’m with you on the insulation. In my early 20’s I put some Cibia pencil beam lights on my Opel GT and wired it with speaker wire. After a few miles the lights went out and when I opened the hood, I saw the insulation was melted and the wires were grounding out. I’m very “sensitive” about insulation and heat. But the guy IS an electrician and DID use math to support his wiring. I’m not particularly concerned because I don’t think these lights will ever see any serious use - if any at all. :-)

Even if the fire has another source, the wiring will get the blame and insurance denial.
It is your call to knowingly participate and consider it okay.
So what voltage are they wired at? What is the voltage rating of the CAT5 cable. The math should not be limited to only amperage. I am a registered professional electrical engineer specialized in power systems. I correct mistakes made by electricians all the time.
