To Whom It May Concern:

I have read the available literature concerning Sx3 (GCI Technology) , which are terminating devices that detect high temperatures resulting from loose connections and remove power to the circuit in question before a fire occurs.

Most experts tend to agree that terminations are the greatest source of electrical arcing and resistance heating, which ultimately may lead to fire.

GCI technology can be incorporated into various splicing devices (for joining conductors), and end-of-line devices such as receptacles, switches, luminaires, appliances, and circuit breakers. Industrial terminal strips
could incorporate Sx3 technology as well.

GCI devices would appear to work well with differential devices connected to main incoming power for residences or businesses, as differentials generally trip very fast when a ground fault is sensed.


Initial installation cost will be minimal, with no additional labor required. When commercially available and listed by a Nationally Recognized Testing Laboratory (NRTL), I would imagine that the National
Fire Protection Agency (NFPA) will be very interested in these devices. In fact, I believe that the National Electrical Code (NPFA 70) may wish to incorporate GCI Technology devices within the requirements of the Code, in keeping with the purpose of the NEC as stated in Article 90 (A), "The purpose of this Code is the practical safeguarding of persons and property from hazards arising form the use of electricity." (NEC 2008 Edition)

Sincerely,
