instrument cable design(fire retardant or fire resistance)

(OP)
How do you normally define the instrument cable either fire retardant or fire resistant ?

RE: instrument cable design(fire retardant or fire resistance)

Refer to tables in Article 700 of the NEC. Cable types are not defined as fire retardant or fire resistant, they're defined by code letters.

What is your application?

Best to you,

Dear DRWeig,
Thank you for taking time.

Application is an instrument cable used for refinery and petro chemical plant.

If country regulation (such as fire and gas) exists, we shall follow it. Otherwise, EPC contractor needs to hear the owner company self-regulation. This is my understanding.

I would like to hear other instrument engineer experiences since common practice for power cables specification may be different from instrument cables.

RE: instrument cable design(fire retardant or fire resistance)

DRWeig,

The NEC applies to the USA. There are other places called 'the rest of the world' where the NEC is a vaguely interesting sideshow with no legal significance.

Isn't it worth establishing where the OP is and what code he is governed by before quoting the NEC at him...?

RE: instrument cable design(fire retardant or fire resistance)

At the current rate of response and quality of response, it shouldn't take more than two thousand more questions to find out where in hell the project is...

Sorry Scotty, I humbly admit my lack of location thought...
