Arc-Resistant CSST In the 2018 edition of NFPA 54, the use of arc-resistant CSST (black jacket) had been approved in section 7.12.3. The new code allows for this product to be treated like non-CSST pipe and tubing for bonding purposes, only requiring bonding to an effective ground fault current path. The arc-resistant jacket does not rely on bonding to …

So, where did the term “arc resistant IR window come from?” Some manufacturers claim to have an “arc resistant IR window” if that window has taken part in a test for arc-resistant switchgear — such as the tests outlined in the ANSI/IEEE C37.20.7, EIC 298, and IEC 62271-200 standards for performing arc fault testing on the switchgear.
· ARC HEAT RESISTANT SILICONE. A durable, heat resistant, one component silicone with a temperature resistance up to 300ºC. Designed for forming gasket joints, bonding oven doors and other surfaces subject to high temperatures. Category: Sealants.
Arc Resistant Switchgear. ANSI/IEEE C37.20.7 defines switchgear arc resistance in two basic categories: ANSI type 1. Arc resistance from the front of gear only. ANSI type 2. Arc resistance provided from the front, sides and rear. A suffix may be added to either of these two types to further define the type of protection provided: A: Basic design.

· EEMAC refers to switchgear that is “internal arc tested” or has an “arc resistant construction”. The IEEE uses the terms “arc-resistant” and “arc-resistant switchgear”. And the IEC “classifies” internal arc resistance while the IEEE “rates” it. There lies the only possible terminological confusion: when NFPA 70E speaks ...
