Is This a Proper Fix for a Double tap

[tglaze (Thomas Glaze)]

Older, but good info…

Has anyone heard of breakers that allow double tapping?

Hi Everyone, I’m fairly new, but the other day I spoke to a residential electrician and he mentioned that Square D (and perhaps another manufacturer) makes a breaker that can withstand the additional amperage that comes with a double tap. Has anyone else encountered a breaker like this? If so, does this mean that InterNACHI’s curriculum needs to be revised?
