•  Both metal fittings (NSC) and green wires (NGL) are bonded to a coaxial shield inside the cable.  The cables will carry the high voltage secondary power and will also provide a built in continuous ground path.  
• POWERFLEX™ is not GTO, it is Neon Sign Cable.  It has been tested to meet the standards required for GTO-15 and has also passed all tests required for liquid-tight metallic conduit and fittings.  These include, but are not limited to:  UV, water absorption, crush, flame, impact and shock hazard tests.
•  The outer yellow jacket of the POWERFLEX™ Neon Sign Cable can be painted for aesthetic purposes.
•  POWERFLEX™ can be used in areas that do not require UL conformance and UL Listed signs and will function perfectly with transformers that do not have ground fault protection.
•  POWERFLEX™ Neon Sign Cable meets the requirements of the National Electric Code.  Section 600-32(a) of the NEC covers wiring methods for neon secondary circuits over 1000 Volts.  Neon Sign Cable has been specifically tested and listed for the purpose of conducting secondary high voltage without being enclosed in conduit and with no clearance requirements to the outer yellow jacket.
• Neon Sign Cable, like GTO in metallic conduit, is restricted to leads no more than 20' long from the transformer to the first electrode.  It is recommended to keep transformer leads under 10' when possible, especially when larger transformers are used.
•  Neon Sign Cables for up to 100' can be special ordered for virtual ground runs or mid-point returns.
•  Each POWERFLEX cable is a finished UL Listed product.  All components of the cable are UL Listed, and do not require individual UL marks.
