what do you all use for end sealing cables, crouse hinds epoxy TSC? it isn't clearly labelled for this. what else is available?

i'm talking about when you run cable capable of transmitting gases in rigid, don't open the jacket in the seal off but seal the cable end in the enclosure where it terminates.

If you were running ONLY multiconductor cable such as TC-ER or MC-HL (no conduit) you could use the TSC Epoxy Sealing compound along with a TMCX connector. But since the cable is routed within conduit, I believe you'll to have to use a conduit seal - such as EYS - open the jacket/separate the conductors and apply Chico compound.

are you thinking of listed? its different
The sealant must be explosion proof vs nonexplosion proof or simply “minimizing gases “ such as duct seal - it must be listed or labeled. Once it has been listed by an approved means it can then be approved the AHJ

TSC is listed for explosion-proof seals

and no seal completely seals out gases, all of them only minimize


why the h*** do you think the code allows this?

Exactly TSC is used with cable seals - why don’t you try reading from the beginning post pretty please

why don't you try reading the code book?


i agree tsc is for cable seals, always thought that. this post provides no good argument or information
