Welcome to our forum.
i think the important distinction is: "connected by wire OUTSIDE of spas"Aren't the stereos built in? I'm no electrician. One way to know for sure is to wait and see how the hot dealers react (if they remove all radios, then i think we've found our answer)
Does this mean that any company that uses a portable device as their stereo would loose their U.L. approval and could infact be producing an unsafe product?
In my opinion.........calling the audio cable running from an Ipod to the spa audio input jack an "unsafe wire" is a stretch. The voltages present on this type of wire is measured in millivolts, and only a few at that. One millivolt equals .001 volts, or 1 x 10 to the -3 power for those of you who prefer scientific notation. My point is, I could safely place the stereo audio cable from an Ipod in my mouth, with no negative effect, other than looking ridiculoous. I am sure some salespeople will start using this UL "info" to slam a competitors spa. I can here it now, " brand x spas are not safe like ours, they let you plug an Ipod with a thin little wire, and Underwear Laxatives tells us that can kill you! So buy our Supersafe wireless spa"
Marquis and Master Spas are the only spas I know that have entire models listed by UL. Are there any others?
