Does sealing of a penetration of a exterior wall of a house need to be fire proof?

[Arcflasher]

I am running a conduit of cat5 inside, from basement of a house going through the exterior wall to a detached garage. I was just curious as someone in a home depot store had mentioned in order to seal the hole, made in the exterior wall of the house for the exterior electrical box, it needs to be sealed with fire sealant or something. I was just curious if this is new code or something. I was just gonna put either electrical duct putty, silicone, or foam spray to seal it. But that mention of the fire sealant got me thinking if it was mandatory or not.

Any advice would greatly help me thank you!

Thanks for the help!

@archflasher yes it should be fire sealant but it’s your house and use what you want to I don’t see a problem with that. Welcome to the forum and good luck
