GPO-3 means what?
(OP)
Hi I have a general question aout NEMA GPO-3. Is this just a general spec. for flame retardency, track resistance etc or does 'GPO-3' specify certain materials to be used? Eg. I know it's glass/polyester but is that written into the spec or could otyher plastics be used?
I guess i'm just trying to get an idea of the scope of what 'GPO-3' means.
Thanks.

FWIW GPO-3 is IMHO a specific material, conforming to a MIL SPEC.
The MIL SPEC is available (for free) at everyspec.com.

UL94V-0 flammability.
Great stuff... Available from MANY vendors as well as just places like mcmaster.com,etc...
Combining good electrical insulation with arc resistance and high strength, GPO3 fiberglass is a good choice for use in electrical applications. Made of fiberglass-reinforced polyester, this material is also known as polyester-grade industrial laminate. Meets UL 94V0 for flame retardance, except tubes, rods, and 1/32" thick sheets do not.
