Re: UL Tesla Coil



And, most important, UL is not so much concerned with electrical shock
hazard (that is more of a OSHA or Consumer Product Safety Issue (in the
US)), but with whether the device can start a fire.  UL is Underwriter's
Labs .. those are fire insurance underwriters being referred to.

In some cities and counties (e.g. Los Angeles) it is illegal to sell any
device not UL listed, or alternately, certified by a Los Angeles mfr
approved to do this.
